Appwrite
Open-source Firebase alternative
Free tier + paidDatabases & backendappwrite.io
What it is
Self-hostable backend covering databases, authentication with dozens of OAuth providers, file storage, serverless functions, messaging and static site hosting via Appwrite Sites. The free cloud plan covers 2 projects, 75,000 monthly active users and 750,000 function executions. Pro starts at $25 per member monthly.
Why it earns a slot
The most generous free MAU allowance here at 75,000, and you can move the whole thing onto your own Docker host if the bill or the terms ever change. Official MCP servers exist for both the API and the docs.
Know before you commit
Free cloud projects are paused after 1 week of inactivity. The free tier also caps you at 1 database, 1 bucket and 2 functions per project, which is tight for anything real.
