TypeScript backends with relational DBs (PostgreSQL, MySQL, SQLite, SQL Server). Projects where type safety and DX matter. Next.js full-stack apps.
Use SQLAlchemy in any Python application that talks to a relational database — web apps, data pipelines, ETL scripts. It supports PostgreSQL, MySQL, SQLite, and Oracle, so the same code runs everywhere. It's the standard ORM in the Python ecosystem, with integrations for Flask, FastAPI, and most web frameworks.
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).
SQLAlchemy's full ORM is overkill for simple read-only queries or scripts that just need to run a few SQL statements. For those cases, use the database's driver directly (psycopg2, sqlite3) or a lightweight query builder like databases.
