Fitz is a new programming language built in Rust, with a gradually-typed compiler. The pitch: instead of stacking FastAPI + SQLAlchemy + python-jose + Celery + Pydantic + uvicorn + Alembic + typer on top of Python, the things they each solve live inside the language: HTTP routing, OpenAPI/AsyncAPI generation, async/await, JWT auth, password hashing, an ORM with a pure-Rust Postgres driver, schema migrations, WebSockets, cron, background jobs, a CLI builder, healthchecks, observability with OpenTelemetry, secrets as opaque types, and a fitz deploy orchestrator. One binary. Zero external deps for the core stack. Repo: github.com/Thegreekman76/fitz · Docs: thegreekman76.github.io/fitz<
I've been building web APIs in Python for years — FastAPI plus the usual cast: SQLAlchemy, python-jose for JWT, passlib for Argon2, Celery + Redis for background jobs, Pydantic for validation, uvicorn for serving, alembic for migrations. Every API I ship needs roughly the same nine libraries, each with its own conventions, its own breaking changes, its own way to integrate with the others.
At some point I asked myself the obvious question: why isn't this just the language?
That question is Fitz.
