Fitz: HTTP, JWT, and Postgres as Language Primitives

Fitz is a Rust-based programming language that consolidates HTTP routing, JWT authentication, database management, and other backend concerns directly into its syntax, eliminating the need for external libraries like FastAPI, SQLAlchemy, and Pydantic. This represents a fundamental shift in how API development is approached: instead of managing dependencies and their incompatibilities, developers get a cohesive, batteries-included language. For teams building modern web services, Fitz could significantly reduce complexity, improve consistency, and accelerate time to production.
