Free projects are paused after 1 week of inactivity. Pro starts at $25 a month with the first project included and more projects from $10 a month. It includes 100,000 MAU (then $0.00325 per MAU), an 8 GB disk per project (then $0.125 per GB), 250 GB of egress (then $0.09 per GB), 100 GB of file storage and 2 million function invocations (then $2 per million). Paid plans include $10 a month of compute credits, enough for one Micro instance.
Appwrite's Free plan allows 2 projects with shared resources, 1 member, 75K monthly active users, 2 GB of storage, 5 GB of bandwidth, 750K function executions, 500K database reads and 250K writes a month. Free projects are also paused after 1 week of inactivity, and you cannot buy more resources on the Free plan. Pro starts at $25 a month with dedicated resources per project: 200K MAU (then $3 per 1,000 users), 150 GB of storage, 2 TB of bandwidth, 3.5M executions (then $2 per million), unlimited members and daily backups. Extra projects on Pro cost $15 each.
The database decides most of it
Supabase gives every project its own Postgres instance. You get SQL, joins, foreign keys, extensions and row level security, and you can connect any Postgres tool. Compute is billed hourly by instance size, from Micro at $10 a month.
Appwrite's default database is TablesDB, used through its SDKs and APIs, with serverless read and write quotas on each plan. Its pricing page also lists dedicated databases from $10 a month per database, including PostgreSQL and MySQL, for teams that want reserved compute.
Auth, storage, functions and more
Both include auth with social logins, file storage with access rules, server functions and realtime. Appwrite also bundles messaging, site hosting, a firewall and analytics events in the same subscription. Supabase adds vectors, cron jobs and queues as Postgres modules.
When to pick Supabase
- Your data is relational and you want SQL.
- You want a standard Postgres database you can move elsewhere.
- Your team is large, since members are unlimited on every plan.
When to pick Appwrite
- You want one platform for auth, data, files, functions, messaging and hosting.
- You expect many users or function executions on a small budget.
- You want an open source backend you could host yourself later.

FAQ
Is Appwrite cheaper than Supabase?
Both Pro plans start at $25 a month. Appwrite Pro includes more users (200K MAU against 100,000), more bandwidth (2 TB against 250 GB of egress) and more executions. Supabase Pro includes $10 a month of compute credits for one Micro Postgres instance. Which costs less depends on what your app uses most, so price your own usage on both pages.
Do free projects pause on both?
Yes. Both pricing pages say free projects are paused after 1 week of inactivity, and both limit the Free plan to 2 projects. Paid plans do not pause projects.
What happens when I hit a Free plan limit?
Appwrite says a Free project freezes and the console goes read only until you upgrade, remove resources or the next billing cycle starts. On Pro, both services keep running and bill the overage, and Appwrite lets you set a budget cap.
Does Appwrite support Postgres?
Appwrite's pricing page lists PostgreSQL and MySQL among the dedicated database types, from $10 a month per database, next to its default TablesDB. Supabase gives every project a dedicated Postgres instance on every plan.
