FastAPI + Django: Two Great Tastes
Django for the batteries — admin, ORM, auth. FastAPI for the hot, async, typed API paths. They coexist happily when you split by responsibility, not by dogma.
The internet wants you to pick a side: Django or FastAPI. In practice I've shipped products that happily run both, because they're good at different things and 'best tool for the job' beats brand loyalty.
Where Django earns its keep
Django's admin, ORM, migrations and auth are a genuine superpower for anything CRUD-heavy or content-shaped. You get a working back office on day one instead of week six. For the boring 80% of an app, that batteries-included head start is hard to beat.
Where FastAPI shines
For high-throughput, async, or heavily-typed API surfaces — webhooks, real-time endpoints, anything talking to an LLM — FastAPI's async model and Pydantic typing are a joy. The request path is lean and the auto-generated docs keep the contract honest.
Letting them coexist
Split by responsibility, not religion. Django owns the data model and admin; FastAPI serves the hot paths, sharing the same database. Draw a clean seam between them and you get the best of both without a civil war in the codebase.
