When to use each

alembic

Any production SQLAlchemy app. Column additions/renames, index creation, constraint changes, data backfills as part of schema migrations.

prisma

TypeScript backends with relational DBs (PostgreSQL, MySQL, SQLite, SQL Server). Projects where type safety and DX matter. Next.js full-stack apps.

When to skip each

alembic

Non-SQLAlchemy databases (use Flyway, Liquibase, or Django migrations). Throwaway dev DBs where you can afford to drop and recreate.

prisma

If you need very complex SQL that Prisma can't express — you can fall back to $queryRaw. Pure NoSQL (use Mongoose for MongoDB). Extreme performance-critical paths (Prisma adds overhead vs raw SQL).
