M0 Free
Free 512 MB shared cluster (M0), always free, available on AWS/Azure/GCP. Includes Atlas Vector Search for AI/RAG applications
- Atlas automatically pauses Free (M0) clusters after 30 days of inactivity where there are zero connections to the cluster. (From mongodb.com/docs/atlas/reference/free-shared-limitations, read 2026-10-18.)
- A Free cluster allows at most 500 connections and 100 read and write operations per second; operations over that limit are queued. (From mongodb.com/docs/atlas/reference/free-shared-limitations, read 2026-10-18.)
- MongoDB Atlas's free M0 cluster needs no credit card. (From mongodb.com/resources/basics/databases/cloud-databases/free-cloud-database, read 2026-10-22.)
- An agent can create a MongoDB Atlas M0 cluster via the API without an account. A person must sign in to claim the cluster, which then becomes a standard Free cluster with no expiration. Unclaimed clusters pause after 2 days and delete after 7. (From mongodb.com/docs/atlas/tutorial/create-ephemeral-cluster, read 2026-10-22.)
- The Flex tier has a monthly base price of $8.00, which includes 5GB storage, 100 operations per second and unlimited data transfer. More operations per second cost extra by tier, and Flex clusters are capped at $30 per month. (From mongodb.com/docs/atlas/billing/atlas-flex-costs, read 2026-10-29.)
- Flex clusters limit total data storage to 5 GB and the number of read and write operations to 500 operations per second. (From mongodb.com/docs/atlas/reference/flex-limitations, read 2026-10-29.)
- Upgrading a Free cluster asks for payment information and starts billing. Changing from a Free cluster to a Flex cluster requires downtime. (From mongodb.com/docs/atlas/scale-cluster, 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.
