The question developers should ask isn't "what's free?" — it's "what will still be free in a year?"

We track 554 pricing changes across the developer tool ecosystem. The data shows a clear pattern: 427 negative changes (free tier removals, limit reductions, restrictions) vs 92 positive changes (expansions, new tiers). Free tier erosion is real, but not universal — some vendors are actively expanding.

This index scores 37 major developer tools by free tier sustainability, using our deal change data, company financial signals, and competitive dynamics. Build on the greens, watch the yellows, plan exits from the reds.

The grades are editorial. Grades set 2026-03-26, one revised 2026-09-05, and each row below carries the date its own grade was set. They do not move on their own, so section 6 scores them against every change we have tracked since — band by band, with the vendors that took nothing left in the denominator.

FAQ

1. How We Score Risk

Our risk scores combine four factors, weighted by predictive value.

Pricing History (40% weight)

Has this vendor changed pricing before? How recently? What direction? A vendor with 2+ negative changes in 12 months is flagged high risk. Vendors actively expanding get a boost. Data source: our 554 tracked deal changes. 1 of the 37 graded vendors have no record in that log at all — CockroachDB — so this factor supplied nothing for them and their grade rests on financial signals, competitive pressure and free tier strategic value.

Financial Signals (25% weight)

Is the company profitable, or VC-subsidized? Has it been acquired recently? IPO pressure, acquisition integration, and runway concerns all increase risk. Microsoft-backed (GitHub), Alphabet-backed (Google Cloud), and profitable companies (Cloudflare) score lower risk.

Competitive Pressure (20% weight)

Does the vendor face strong competition in its category? Intense competition (AI/ML APIs, hosting) forces vendors to maintain free tiers as acquisition tools. Monopolistic positions (Spotify API) allow vendors to extract more value.

Free Tier Strategic Value (15% weight)

Is the free tier a strategic funnel (developer acquisition tool) or a cost center? Vendors whose business model depends on developer adoption (Cloudflare, Auth0) are more likely to preserve free tiers. Vendors where free users are a cost (Heroku under Salesforce) are likely to cut.

2. 🟢 Low Risk — Safe to Build On

These vendors have stable free tiers backed by profitable companies, competitive pressure, and strategic value. Build on these with confidence.

Vendor	Risk	Category	Reasoning	Last Change	Tracked since graded
Cloudflare	🟢 Low Risk graded 2026-03-26	Cloud/CDN	Actively expanding free tiers (Workers, Pages, Queues added free Feb 2026). Profitable, no VC subsidy pressure. Free tier is a strategic funnel — core business is paid enterprise CDN.	2026-02-04 before the grade	discovered 2026-09-02 · effective date unknown limits_increased not a free tier negative
GitHub	🟢 Low Risk graded 2026-03-26	Version Control	Microsoft-backed, free tier stable since 2019. Actions self-hosted runner fee was proposed then postponed after backlash (Jan 2026). Track record of expanding, not contracting.	2026-01-01 before the grade	discovered 2026-09-02 · effective date unknown pricing_restructured not a free tier negative discovered 2026-09-09 · effective date unknown pricing_restructured not a free tier negative
Grafana Cloud	🟢 Low Risk graded 2026-03-26	Monitoring	Open-source core (Prometheus, Loki, Tempo). Free tier includes 10K metrics, 50 GB logs, 50 GB traces. Company profitable, recent IPO path. Open-source foundation means community forks prevent lock-in.	—	discovered 2026-09-02 · effective date unknown pricing_restructured not a free tier negative
CockroachDB	🟢 Low Risk graded 2026-03-26	Databases	10 GB free storage, multi-region support. Backed by $633M funding. Free tier is strategic acquisition tool. Serverless model scales naturally.	—	No change has ever been tracked for CockroachDB. This grade rests on financial signals, competitive pressure and free tier strategic value — not on our deal change data.
Auth0	🟢 Low Risk graded 2026-03-26	Authentication	Okta-owned (enterprise backing). Limits increased Nov 2025 (25K MAU → expanded). Free tier is developer funnel for enterprise IAM.	2025-11-01 before the grade	Nothing tracked since it was graded.
Sentry	🟢 Low Risk graded 2026-03-26	Error Tracking	Open-source core. Pricing restructured Aug 2025 but free tier preserved (5K errors/mo). Community edition available as fallback.	2025-08-15 before the grade	Nothing tracked since it was graded.
Google Cloud (Always Free)	🟢 Low Risk graded 2026-03-26	Cloud IaaS	Google Always Free tier unchanged for years — f1-micro VM, 5 GB Cloud Storage, BigQuery 1 TB/mo. Separate from promotional credits. Backed by Alphabet's cloud growth strategy.	2026-01-01 before the grade	Nothing tracked since it was graded.
AWS Free Tier	🟢 Low Risk graded 2026-03-26	Cloud IaaS	12-month free tier + always-free services (Lambda 1M requests, DynamoDB 25 GB). AWS is the market leader — free tier is a training/onboarding tool, not a cost center. Restructured Jan 2026 but expanded.	2026-01-04 before the grade	effective 2026-04-20 product_deprecated not counted — a deprecation of a different product by the same vendor effective 2026-04-30 product_deprecated not counted — a deprecation of a different product by the same vendor effective 2026-04-30 product_deprecated not counted — a deprecation of a different product by the same vendor effective 2026-06-30 product_deprecated not counted — a deprecation of a different product by the same vendor effective 2026-09-30 product_deprecated not counted — a deprecation of a different product by the same vendor effective 2026-10-07 product_deprecated not counted — a deprecation of a different product by the same vendor
GitHub Copilot Free	🟢 Low Risk graded 2026-03-26	AI Coding	New free tier launched Dec 2025 (2K completions + 50 chat/mo). Microsoft strategic investment in AI developer tools. Competitive pressure from Cursor/Claude ensures free tier stays.	2025-12-18 before the grade	effective 2026-04-10 restriction not counted — reversed or retracted since we recorded it effective 2026-04-20 restriction not counted — reversed or retracted since we recorded it effective 2026-04-22 restriction not counted — reversed or retracted since we recorded it discovered 2026-08-28 · effective date unknown pricing_restructured not a free tier negative
Anthropic	🟢 Low Risk graded 2026-03-26	AI/ML APIs	Limits increased Feb 2026 and Mar 2026. Currently in growth mode, well-funded ($7.3B raised). Free API tier is competitive necessity against OpenAI/Google.	2026-03-13 before the grade	discovered 2026-09-02 · effective date unknown pricing_model_change not a free tier negative

Pattern: The safest free tiers share three traits: (1) backed by profitable or well-capitalized companies, (2) the free tier is a strategic funnel for paid products, and (3) strong competitive pressure prevents removal. Cloudflare and GitHub are the gold standard — both have expanded free tiers while competitors contracted.

3. 🟡 Medium Risk — Use with Caution

Free tiers that still exist but show signals of tightening. Use these, but have a migration plan and monitor for changes.

Vendor	Risk	Category	Reasoning	Last Change	Tracked since graded
Supabase	🟡 Medium Risk graded 2026-03-26	Databases/BaaS	Project pause tightened to 1 week inactivity (Feb 2026). Core free tier preserved but signals efficiency pressure. Post-Series C ($80M) — profitable path unclear.	2026-02-01 before the grade	discovered 2026-09-03 · effective date unknown pricing_restructured not a free tier negative
Vercel	🟡 Medium Risk graded 2026-03-26	Hosting	Restructured to credit-based model (Jan 2026). Free tier still generous for personal projects but commercial use restricted (Hobby plan). Watch for further tightening.	2026-01-01 before the grade	discovered 2026-09-07 · effective date unknown limits_reduced counted against the grade
Netlify	🟡 Medium Risk graded 2026-03-26	Hosting	Restructured to credit-based pricing (Sep 2025) — sites pause on exhaustion. 300 credits/month is sufficient for small sites but represents a philosophical shift toward metered billing.	2025-09-04 before the grade	effective 2026-04-14 limits_increased not a free tier negative effective 2026-04-17 pricing_model_change not a free tier negative discovered 2026-09-07 · effective date unknown pricing_restructured not a free tier negative
Neon	🟡 Medium Risk graded 2026-03-26	Databases	Pricing restructured Jan 2026 post-Databricks acquisition. Free tier preserved (0.5 GB/project, 100 projects) but acquisition creates uncertainty about long-term free tier commitment.	2026-01-15 before the grade	Nothing tracked since it was graded.
Railway	🟡 Medium Risk graded 2026-03-26	Hosting/PaaS	Free tier expanded with $100M Series B (Oct 2025). Currently generous ($5 credit, no sleep). But VC-funded PaaS companies have a history of removing free tiers (see: Heroku). Watch burn rate.	2025-10-01 before the grade	discovered 2026-09-03 · effective date unknown limits_reduced counted against the grade
Render	🟡 Medium Risk graded 2026-03-26	Hosting/PaaS	Sleep time reduced (Sep 2025) — 15-min spin-down is aggressive. Free PostgreSQL limited to 256 MB with 30-day expiry. Signals tightening, though core free tier intact.	2025-09-01 before the grade	discovered 2026-09-02 · effective date unknown pricing_restructured not a free tier negative
Stripe	🟡 Medium Risk graded 2026-03-26	Payments	Processing fees restructured Feb 2026 (2.7% + 5¢ domestic card). No free tier per se — pay-per-transaction model. Risk is in rate changes, not tier removal.	2026-02-01 before the grade	Nothing tracked since it was graded.
Firebase	🟡 Medium Risk graded 2026-03-26	BaaS	Multiple changes in 2026: Cloud Storage limits reduced (Feb), Realtime Database EOL announced (Mar), restrictions tightened (Feb). Google consolidating around Firestore. Migration advisable for RTDB users.	2026-03-19 before the grade	Nothing tracked since it was graded.
Docker Hub	🟡 Medium Risk graded 2026-03-26	Containers	Rate limits tightened (Dec 2024) — 100 pulls/6h anonymous, 200 authenticated. Docker Desktop commercial license required for large orgs ($5/user/mo+). Free for small teams but trending paid.	2024-12-10 before the grade	Nothing tracked since it was graded.
Dub.co	🟡 Medium Risk graded 2026-03-26	Dev Utilities	Free tier limits reduced sharply (Mar 2026). Link shortener with declining free allowance signals monetization pressure.	2026-03-22 before the grade	Nothing tracked since it was graded.
Google Gemini API	🟡 Medium Risk graded 2026-03-26	AI/ML	Free tier rate limits slashed 50-80% (Dec 2025). The flagship Gemini 3.1 Pro is paid-only, though Gemini 2.5 Pro is still free. A Google PM admitted generous limits were only for a promotional weekend. Still has free tier but heavily restricted.	2025-12-15 before the grade	effective 2026-04-01 restriction counted against the grade effective 2026-04-08 restriction not counted — reversed or retracted since we recorded it effective 2026-06-01 product_deprecated not counted — a deprecation of a different product by the same vendor discovered 2026-09-03 · effective date unknown pricing_restructured not a free tier negative

Pattern: Medium-risk vendors typically show one or more warning signs: credit-based pricing transitions (Vercel, Netlify), post-acquisition uncertainty (Neon/Databricks), or incremental tightening (Supabase project pausing, Render sleep reduction). The free tier still works today — but the trend line points toward further restrictions.

4. 🔴 High Risk — Plan Your Exit

10 vendors carry the high grade. 4 of them still have a free tier in our catalogue, so an exit is something you can still plan — those are the ones below. The other 6 have nothing left to exit from and are listed under Already Changed instead, because a heading that says plan your exit is an instruction, and an instruction to leave a free tier that is already gone is not one a reader can act on.

Vendor	Risk	Category	Reasoning	Last Change	Tracked since graded
Postman	🔴 High Risk graded 2026-03-26	API Testing	Team collaboration removed from free tier (Mar 2026). Aggressive monetization of previously-free features. Pattern suggests further restrictions ahead.	2026-03-01 before the grade	discovered 2026-09-02 · effective date unknown limits_reduced counted against the grade
OpenAI	🔴 High Risk graded 2026-03-26	AI/ML	Multiple free tier reductions: limits cut Jun 2025, further reduced Feb 2026. GPT-4 free access removed. Market leader extracting value — expect continued tightening.	2026-02-09 before the grade	effective 2026-05-07 product_deprecated not counted — a deprecation of a different product by the same vendor effective 2026-05-12 product_deprecated not counted — a deprecation of a different product by the same vendor effective 2026-08-26 product_deprecated not counted — a deprecation of a different product by the same vendor
HCP Terraform	🔴 High Risk graded 2026-03-26	Infrastructure	Legacy tier EOL March 31, 2026. HashiCorp BSL license change (Aug 2023) already fractured community. IBM acquisition adds enterprise pricing pressure. Migrate to OpenTofu.	2026-03-31	effective 2026-03-31 pricing_restructured not a free tier negative
LocalStack	🔴 High Risk graded 2026-03-26	Testing	Community Edition shut down March 23, 2026. Complete removal of free/OSS option. Migrate to Moto, aws-sdk-mock, or Testcontainers.	2026-03-23 before the grade	effective 2026-04-12 limits_increased not a free tier negative discovered 2026-09-07 · effective date unknown pricing_restructured not a free tier negative

Pattern: High-risk vendors share traits: multiple negative changes in a short period (OpenAI, X/Twitter), hostile stance toward free users (Spotify, Amazon SP-API), or entering "sustaining mode" with no investment (Heroku). When you see a vendor make 2+ negative changes in 6 months, the third is coming.

How this band is split: the grade is editorial and unchanged; only where it renders is derived. A vendor appears above if our catalogue holds a free tier for it today. Heroku (no catalogue record), Fly.io (no free tier in our catalogue), X API (Twitter) (no free tier in our catalogue), Brave Search API (no free tier in our catalogue), Spotify API (no catalogue record), Amazon SP-API (no free tier in our catalogue) did not, so they moved down a section.

5. ⚫ Already Changed — Lessons Learned

Free tiers that no longer exist. Each one is a case study in what to watch for. The 6 vendors carrying the high grade with no free tier left in our catalogue are listed here too, under their own grade.

Vendor	Status	Category	What Happened	Date	Tracked since graded
PlanetScale	⚫ Already Changed graded 2026-03-26	Databases	Free tier removed April 2024. Hobby plan eliminated entirely. Migrate to Neon, Turso, or CockroachDB.	2024-04-08 before the grade	Nothing tracked since it was graded.
Fauna	⚫ Already Changed graded 2026-03-26	Databases	Product deprecated May 2025. Entire service shutting down. Migrate immediately to MongoDB Atlas, CockroachDB, or Supabase.	2025-05-30 before the grade	Nothing tracked since it was graded.
MinIO (OSS)	⚫ Already Changed graded 2026-03-26	Storage	Open-source version killed Feb 2026 (GNU AGPL → proprietary). Self-hosted MinIO is no longer free for production. Use S3-compatible alternatives.	2026-02-12 before the grade	Nothing tracked since it was graded.
SendGrid	⚫ Already Changed graded 2026-03-26	Email	Free tier removed May 2025 under Twilio ownership. Use Resend (3K emails/mo free) or Maileroo (3K/mo); Mailgun and Amazon SES have since dropped their free tiers too.	2025-05-27 before the grade	Nothing tracked since it was graded.
Logz.io	⚫ Already Changed graded 2026-03-26	Logging	Free tier removed Mar 2026. Use Grafana Cloud (50 GB logs free), Axiom (500 GB/mo), or self-hosted ELK.	2026-03-02 before the grade	effective 2026-04-13 free_tier_removed counted against the grade
Freshping	⚫ Already Changed graded 2026-03-26	Monitoring	Free tier removed Mar 2026. Use BetterStack (10 monitors free), UptimeRobot (50 monitors), or Grafana Cloud synthetics.	2026-03-06 before the grade	Nothing tracked since it was graded.
Heroku	🔴 High Risk graded 2026-03-26	Hosting/PaaS	Free tier removed Nov 2022. Now in 'sustaining mode' under Salesforce — minimal investment, no innovation. The canonical cautionary tale for relying on free tiers.	2022-11-28 before the grade	Nothing tracked since it was graded.
Fly.io	🔴 High Risk graded 2026-09-05	Hosting	Free tier removed for new accounts in October 2024. New signups get a trial of 2 hours runtime or 7 days, whichever comes first, then pay-as-you-go from the first machine — the smallest is $2.02/month. Only legacy Hobby/Launch/Scale accounts still carry 3 shared-cpu-1x VMs, 3 GB volume storage and 100 GB transfer. Volume snapshots became billable in January 2026.	2024-10-01 before the grade	Nothing tracked since it was graded.
X API (Twitter)	🔴 High Risk graded 2026-03-26	APIs	Free tier removed twice in 2026 (Feb 1 + Feb 9). Pay-per-use only with $10 one-time credit. Unpredictable management. Do not build on this API without paid plan budget.	2026-02-09 before the grade	effective 2026-04-20 pricing_model_change not a free tier negative
Brave Search API	🔴 High Risk graded 2026-03-26	Search	Free plan (5K queries/mo) replaced with metered billing Feb 2026. No spending cap — credit cards actively charged. Complete removal of free access.	2026-02-12 before the grade	Nothing tracked since it was graded.
Spotify API	🔴 High Risk graded 2026-03-26	APIs	Premium subscription now required for dev mode (Feb 2026). Test users cut from 25 to 5. Multiple endpoints deprecated. Hostile to free developers.	2026-02-11 before the grade	Nothing tracked since it was graded.
Amazon SP-API	🔴 High Risk graded 2026-03-26	APIs	Free access ended after 10+ years — now $1,400/year + per-call fees (Apr 2026). Zero warning. Shows even long-stable APIs can go paid overnight.	2026-01-31 before the grade	effective 2026-04-14 pricing_postponed not a free tier negative

6. Scorecard — How the Grades Have Held Up

A grade nobody scores is not a prediction. Every band below is counted on request against the change log as it stands right now: for the vendors we put in each band, how many have since taken a change that removed a free tier, cut its limits, added a restriction, killed an open-source edition, or deprecated the graded product itself. Vendors that took nothing stay in the denominator.

Band	Vendors graded	Took a free tier negative	Rate	Negative records	Nothing tracked since
🟢 Low Risk	10	0	0%	0	4
🟡 Medium Risk	11	3	27%	3	5
🔴 High Risk	10	1	10%	1	4
⚫ Already Changed	6	1	17%	1	5

What the scorecard does not count. A record is left out if it has since been reversed or retracted, if it came from an index sweep rather than a vendor announcement, or if it deprecates a different product the same vendor sells — an AWS Lambda runtime reaching end of life is not the AWS free tier narrowing. Each vendor's row in the tables above names every record tracked since it was graded and says which of these applied. 18 of the 37 graded vendors have had nothing tracked at all since grading, which is the honest limit on how much any of these rates can carry.

Reading the heatmap: Red bars = negative changes (removals, reductions, restrictions). Green bars = positive changes (expansions, new tiers). Gray = neutral restructurings. Categories with 80%+ negative changes (APIs, Testing, Monitoring) are under the most pricing pressure. AI/ML shows a split — some vendors contracting while new entrants expand.

9. Pattern Analysis — What 554 Changes Tell Us

Statistical patterns from our pricing change dataset that predict future free tier removals.

📊 The Two-Strike Rule

Vendors with 2+ pricing changes in 12 months almost always make a third. From our data, 48 vendors have made multiple changes: AWS (7), OpenAI (5), GitHub Copilot (4), Netlify (4), DigitalOcean (4), Cursor (4), Amazon Kiro (4), Amazon SP-API (3). When you see the second change, start your migration plan — the third is coming.

📈 Changes by Month

Each change is counted in the month its terms took effect. A change read off a page that does not say when it changed is not counted here — those are below, by the month we read the page. Monthly counts: 2022-11: 1, 2023-08: 1, 2024-03: 1, 2024-04: 1, 2024-06: 1, 2024-12: 1, 2025-01: 1, 2025-05: 2, 2025-06: 2, 2025-07: 2, 2025-08: 2, 2025-09: 2, 2025-10: 2, 2025-11: 2, 2025-12: 4, 2026-01: 15, 2026-02: 17, 2026-03: 19, 2026-04: 192, 2026-05: 5, 2026-06: 4, 2026-08: 2, 2026-09: 4, 2026-10: 1. Q1 2026 holds 51 changes whose terms took effect in it, against 14 in the second half of 2025.

Changes Found by Reading a Page (270). These vendors’ pages state terms that differ from what we had stored and do not say when they changed. Each is counted in the month we read the page, so this series measures when we looked, not when the market moved. None of them are in the monthly figures above. Monthly counts: 2026-08: 129, 2026-09: 141.

🏢 The Acquisition Pattern

Acquisitions precede free tier changes by 6-18 months. Pattern examples: Heroku (Salesforce acquisition → free tier removed), HCP Terraform (IBM acquisition → BSL license → legacy tier EOL), Neon (Databricks acquisition → pricing restructured), SendGrid (Twilio acquisition → free tier removed). When a developer tool gets acquired, budget for a paid plan or prepare to migrate.

💰 The Credit-Based Transition

Credit-based pricing is the intermediate step before free tier reduction. Vercel, Netlify, and Fly.io all moved to credit-based models before tightening limits. The credit model lets vendors reduce free usage gradually (lower credits) without the PR hit of "free tier removed." If your vendor announces credits, plan ahead.

🛡️ The Safety Signals

Not all changes are negative. 92 of 554 changes were positive (new tiers or expansions). Safe signals: profitable company with developer funnel business model (Cloudflare, GitHub), open-source core with commercial layer (Grafana, Sentry), and competitive market forcing free tier maintenance (AI coding tools, cloud providers).

10. Counter-Trends — Who's Expanding Free Tiers

While most pricing changes are negative (427 of 554), a meaningful minority of vendors are actively expanding. Understanding why reveals what makes a free tier durable.

The Cloudflare Model

What they did:

Added free Queues, expanded Workers, Durable Objects pricing reduction, launched $250K startup program — all in Q1 2026. More free, not less.

Why it works:

Cloudflare's free tier is a strategic moat, not a cost center. Every free Workers user is a potential enterprise CDN customer. The network effect means more developers → more sites → more edge traffic → more enterprise deals. Free tier investment has positive ROI.

The lesson:

When the free tier IS the business model's funnel (not a charity), it's durable. Look for this pattern: Cloudflare (CDN → enterprise), GitHub (repos → Copilot/Enterprise), Auth0 (dev auth → enterprise IAM).

AI Coding Tools

GitHub Copilot Free (2K completions), Windsurf launch, Anthropic rate increases. The AI coding wars are forcing vendors to compete on free tier generosity. This is the most expansionary category in our dataset.

Cloud Providers

AWS restructured and expanded free tier (Jan 2026). Google Always Free stable for years. Azure Founders Hub offers $150K credits. Big cloud free tiers are acquisition funnels that drive billions in enterprise spend.

Open-Source First

Grafana Cloud (50GB logs free), Sentry (5K errors), Prometheus ecosystem. Open-source core means community forks prevent vendor lock-in — which means the commercial layer must stay competitive.

11. How to Protect Your Stack

Practical Risk Mitigation

Build on abstractions, not implementations

Use ORMs instead of raw database SDKs. Use S3-compatible APIs instead of vendor-specific storage. Use OpenTelemetry instead of vendor-specific APM agents. When the vendor changes, you swap the backend — not the codebase.

Evaluate free tiers like you evaluate dependencies

Before adopting a free tier, check: Is the company profitable? Has pricing changed in the last 12 months? Is there competitive pressure to maintain the free tier? Would your project survive if the free tier disappeared tomorrow? Our pricing change timeline answers the first question.

Multi-vendor for critical infrastructure

Don't put all infrastructure on one vendor's free tier. Combine providers: Cloudflare (CDN/DNS) + Railway or Render (compute) + Neon or Supabase (database) + Resend or Postmark (email). If one changes pricing, you migrate one layer — not everything. See our Free Startup Stack guide for curated combinations.

Watch the signals, not just the announcements

Free tier changes rarely come out of nowhere. Watch for: acquisitions (Neon/Databricks, HashiCorp/IBM), license changes (MinIO AGPL → proprietary), credit-based pricing transitions (Vercel, Netlify), and "sustaining mode" language (Heroku). These precede free tier cuts by 6-18 months.

12. Frequently Asked Questions

How often is the Free Tier Risk Index updated? ▼

The grades are editorial and do not move on their own. Grades set 2026-03-26, one revised 2026-09-05, and every row on the page carries the date its own grade was set. What is recomputed on every request is the record beneath them — each vendor's tracked changes since the day it was graded, and the scorecard showing how each band has fared. Our change log currently holds 554 changes in force across 1,547 developer tools, and we add new changes within 48 hours of announcement.

Which free tiers are safest to build on in 2026? ▼

Cloudflare, GitHub, Grafana Cloud, AWS Always Free, and Google Cloud Always Free are our lowest-risk picks, graded 2026-03-26. They share three traits: backed by profitable companies, the free tier is a strategic acquisition funnel, and strong competitive pressure prevents removal. Section 6 of this page publishes what has happened to each band since.

What are the warning signs that a free tier is about to be removed? ▼

Key signals: (1) acquisition or ownership change (HashiCorp/IBM, Neon/Databricks), (2) license change (MinIO AGPL to proprietary), (3) credit-based pricing transition (Vercel, Netlify), (4) two or more negative changes within 6 months, and (5) 'sustaining mode' language in announcements.

How do you calculate risk scores? ▼

We weight four factors: pricing history (40%) — has the vendor changed before and how recently; financial signals (25%) — profitable vs VC-subsidized, recent acquisitions; competitive pressure (20%) — intense competition keeps free tiers alive; free tier strategic value (15%) — is the free tier a funnel or a cost center. 1 of the 37 graded vendors have no record in our change log at all, so pricing history supplied nothing for them and their grade rests on the other three factors: CockroachDB.

How accurate have the risk grades been? ▼

Grades set 2026-03-26, one revised 2026-09-05, and scored against every change tracked since: low risk 0 of 10 (0%), medium risk 3 of 11 (27%), high risk 1 of 10 (10%), already changed 1 of 6 (17%). A vendor counts if our change log holds a record in force since its grading date that removed a free tier, cut limits, added a restriction, killed an open-source edition, or deprecated the graded product itself. Vendors with nothing tracked stay in the denominator rather than being dropped.

What should I do if a tool I depend on is rated high risk? ▼

Start planning your migration now. Use abstractions (ORMs, S3-compatible APIs, OpenTelemetry) to minimize switching cost. Identify 2-3 alternatives and test them in a staging environment. Subscribe to our pricing change feed at /feed.xml for early warning.

Are there any categories where free tiers are expanding? ▼

Yes — AI coding tools (GitHub Copilot Free, Anthropic increases, Windsurf launch) and cloud infrastructure (Cloudflare Queues, Workers expansion, AWS restructuring). Competition for developer mindshare drives expansion. See the Counter-Trends section for details.
