What this section prints is decided by the calendar, not by anything the vendor did. 3 records here carry a date after 2026-11-14. The vendor has announced them and they have not taken effect, so they are not part of the history below. On its own date a record here joins the Pricing Change Timeline, below.
Firebase keeps running. The Firebase Extensions service can be used until March 31, 2027. Installed extensions keep running after that date. After March 31, 2027, they cannot be updated, reconfigured or uninstalled, and their configuration cannot be downloaded. Google's replacement is function kits in Cloud Functions for Firebase (2nd gen). Source ↗
On December 7, 2026, Chroma Cloud becomes read-only: applications can no longer create, update or delete data in it. On December 22, 2026, Chroma Cloud stops serving reads, so data must be exported before then. Open-source ChromaDB keeps running under the Apache 2.0 license. Chroma announced the wind-down on 2026-10-23, as it joins Replit. Source ↗
Firebase Spark projects that enabled Remote Config before September 1, 2026 can use it under the old terms until December 1, 2026. From December 1, 2026, the 100,000-fetches-a-day limit applies to them, with 30 days of full service from the first day they go over, then throttling unless they upgrade to Blaze. A Spark project that upgrades to Blaze before November 15, 2026 is not billed for Remote Config until February 1, 2027. Blaze projects from before September 1, 2026 start Remote Config billing on February 1, 2027. Source ↗
Pricing Change Timeline
Every record we hold is listed here, newest first. A record is never removed from this list, so a vendor named here stays named here whatever its verdict does afterwards.

The free tier now includes a compute instance with 0.25 vCPU and 1 GB memory, but also lists several paid tiers with varying compute and storage options. The free tier is now explicitly a 'Start' plan with hourly billing for additional resources beyond the free limits. Source ↗
Prisma stopped offering Accelerate for new setups in its Console by 2026-10-02, and Accelerate, including Prisma Postgres connections that go through it, is retired on 2026-12-01. Existing Accelerate connections keep working until then. Prisma Postgres keeps running, and its databases come with connection pooling. Source ↗
CockroachDB stopped offering its free Basic plan (50 million RUs and 10 GiB of storage free per month) to new deployments on 2026-09-15, when it moved new clusters to Cockroach Continuum pricing. New Cloud organizations now get a 30-day free trial with $400 in credit. Clusters created before 2026-09-15 stay on their existing plans during their current term. Source ↗
model changeChromadiscovered 2026-09-07 · effective date unknownhigh
The free tier has changed. The current pricing page shows a Starter plan with $5 in free credits and usage-based pricing for writes, storage, and queries. Unconfirmed. We could not check this change against an archived copy of Chroma's page, so it does not count toward the rating.Source ↗
increasedPrisma Accelerateeffective between 2026-07-31 and 2026-08-27medium
The free tier now offers 200,000 operations/month for Prisma Postgres, not 100,000 operations/month. The free tier also includes 1M requests/month for Prisma Compute, 360 GB-hours memory, 4 active vCPU-hours, and 10 GB outbound bandwidth. Source ↗
From September 1, 2026, Firebase limits Remote Config on the no-cost Spark plan to 100,000 fetch requests a day per project. A Spark project over the limit keeps full service for 30 days from the first day it goes over, and after that requests above the limit are throttled unless it upgrades to Blaze. Blaze has the same 100,000 a day at no cost and then $0.06 per 10,000 requests. Firebase's pricing page had listed Remote Config as no-cost before. This applies to projects that enable Remote Config on or after September 1, 2026. Older Spark projects follow on December 1, 2026. Source ↗

Previously 'up to $50,000 for a year with 50% off'. Unconfirmed. We could not check this change against an archived copy of ScaleGrid Startup Program's page, so it does not count toward the rating.Source ↗

At-Risk Vendors
All 4 of the 45 vendors we list in this category that carry one. A vendor is named here for as long as a demotion is in force against it: a one-off pricing event, recorded against a source we cite, whose date falls in the last 180 days — or a standing condition, also cited, such as a product retired or a free tier withdrawn and not restored, which does not expire with time. A demotion can lift with nothing about the vendor having changed, and that happens on the day the vendor's newest qualifying event passes 180 days.
All 27 of the 45 vendors we list in this category that qualify, not a selection of them. A vendor is named here for as long as no demotion is in force against it and we hold no change record for it dated in the last 90 days — any record, including ones the timeline above does not count. A vendor can join this section on a day we recorded nothing about it, when the later of those two clocks runs out: 90 days after its newest record, or the day the demotion against it lapses. It leaves on the day we file a new record, or the day we can no longer vouch for the terms we list.
