Prisma
Schema-first TypeScript ORM
Free tier + paidDatabases & backendprisma.io
What it is
A schema-first ORM that generates a fully typed client from a declarative
schema.prisma file, with its own migration engine and a Studio data browser. The company also sells Prisma Postgres, a managed database whose free plan covers 100,000 operations monthly and 500MB across up to 50 databases.Why it earns a slot
That single schema file is the most legible way to hand a data model to an agent, and there is more Prisma than any other TypeScript ORM in training data. The official MCP server at
mcp.prisma.io includes a docs search tool.Know before you commit
Historically a heavy Rust query engine bloated serverless bundles and added cold-start latency; newer versions moved to TypeScript, so check your deployment target. Connection pooling still matters on serverless.
Getting started
