SQLite at the edge — 5M rows read/day, 100K rows written/day, 5 GB total storage. Resets daily at midnight UTC
- On the Free plan, once the account reaches its daily read or write limit, D1 refuses queries and returns errors until the limits reset at 00:00 UTC; upgrading to Workers Paid removes the limits. (From developers.cloudflare.com/d1/platform/pricing, read 2026-10-20.)
- On the Free plan a single D1 database can hold at most 500 MB, and an account can have at most 10 databases, within the 5 GB account total. (From developers.cloudflare.com/d1/platform/limits, read 2026-10-20.)
- Cloudflare D1's free plan needs no credit card. (From cloudflare.com/developer-platform/products/d1, read 2026-10-22.)
- D1 usage past Free limits requires the Workers Paid plan. That plan has a minimum charge of $5 per month per account. (From developers.cloudflare.com/workers/platform/pricing, read 2026-10-29.)
- The Workers Paid plan includes 25 billion rows read, 50 million rows written, and 5 GB storage monthly. Rows read overage is $0.001 per million. Rows written overage is $1.00 per million. Storage overage is $0.75 per GB-mo. There are no egress charges. (From developers.cloudflare.com/d1/platform/pricing, read 2026-10-29.)
- Time Travel restores a database from up to 30 days ago on Workers Paid and 7 days on Free. The paid plan has a 10 GB maximum database size and 1 TB storage per account. (From developers.cloudflare.com/d1/platform/limits, read 2026-10-29.)

Open-source BaaS — 75K MAU, 2 GB storage, 750K function executions/month, 5 GB bandwidth, 1 database, 1 bucket and 2 functions per project, 500K database reads and 250K writes a month. Limit of 2 projects.
- The Free plan's resources are shared across the account's 2 projects, which draw on one allowance. Paid plans give each project its own resources. (From appwrite.io/docs/advanced/billing/free, read 2026-10-11.)
- A Free project with no development activity in the Appwrite Console for 7 days is paused. User traffic does not prevent pausing. The project becomes inaccessible to users and stops running backups, cron jobs, and scheduled functions until reactivated in the Console. (From appwrite.io/changelog/entry/2026-02-20-1, read 2026-10-11.)
- Free projects are deleted after 90 days paused. (From appwrite.io/changelog/entry/2026-06-29, read 2026-10-05.)
- From October 19, 2026, cron schedules for functions on Appwrite Cloud need a paid plan. On the Free and Education plans, functions run only on an interval of 60 minutes or longer. Existing cron schedules become intervals close to how often they ran. (From appwrite.io/changelog/entry/2026-10-15-1, read 2026-10-19.)
- If a Free project reaches any resource limit, such as function executions or monthly active users, it freezes and the Console becomes read-only until the next billing cycle, or the owner upgrades to Pro or removes the resources over the limit. (From appwrite.io/pricing, read 2026-10-05.)
- From November 5, 2026, Appwrite Cloud deletes inactive function and site deployments more than 30 days old by default. A deployment's age counts from the day it was created. The active deployment and any deployment a custom domain points to are kept. On the Free plan, retention can be raised to at most 90 days and each function or site keeps at most its 100 newest inactive deployments. (From appwrite.io/blog/post/default-deployment-retention, read 2026-10-22.)
- On the Free plan, inactive deployments count toward the same 2 GB of storage as files and databases. (From appwrite.io/blog/post/default-deployment-retention, read 2026-10-22.)
- Pro starts at $25 a month. It includes one project with 2TB bandwidth, 150GB storage, 3.5M executions and 200K monthly active users. Each additional project costs $15. (From appwrite.io/pricing, read 2026-10-29.)
- Additional API bandwidth costs $15 per 100GB a month. Additional storage costs $2.8 per 100GB. Additional executions cost $2 per 1m. Additional users cost $3 per 1,000 users. Additional reads cost $0.060 per 100k and writes $0.10 per 100k. (From appwrite.io/pricing, read 2026-10-29.)
- On Pro, Appwrite automatically buys extra resources when an organization exceeds its limits. The budget cap limits how much it can scale. (From appwrite.io/docs/advanced/billing/pro, read 2026-10-29.)

−1 stale_verification We cannot confirm this offer: 1 consecutive re-check attempt has failed (most recently 2026-11-02 — The pricing page text is truncated and focuses on database compute pricing and FAQ; it does not include the Free plan's specific limits (MAU, storage, function executions, bandwidth, database/bucket/function counts, reads/writes, or project limit), so the stored free-tier details cannot be verified against it.), never confirmed since it was indexed. This is our inability to verify, not a change by the vendor.
