MongoDB Atlas

Managed document database

Free tier + paidDatabases & backendmongodb.com

What it is

Managed hosting for MongoDB's document model, with Atlas Search, vector search and change streams built in. The M0 shared cluster is free forever with 512MB of storage and roughly 100 operations per second. The next step up is Flex at up to $30 monthly, then a dedicated M10 around $57.

Why it earns a slot

Schemaless documents suit prototypes where the shape of the data is still moving, which describes most vibe-coded apps. MongoDB ships an official MCP server plus an Atlas-managed remote MCP endpoint for agent access to live data.

Know before you commit

M0 clusters are paused after roughly 60 days of inactivity and there are no backups on the free tier. The jump from free to a dedicated cluster is a steep price cliff.
