Fitz vs FastAPI: JWT auth with zero extra libraries
A developer compares building JWT auth, RBAC, and token blacklisting in FastAPI (requiring five libraries) versus Fitz, where everything is built into the language. Fitz uses Argon2id hashing, JWT sign/verify, and stackable RBAC without external dependencies. The post argues that Fitz reduces complexity and glue code for common auth flows.

The comparison is useful for Python developers evaluating frameworks, but Fitz is a niche language—this won't replace FastAPI's ecosystem anytime soon.
