TurboAPI is a high-performance web framework designed as a drop-in replacement for FastAPI. It achieves significant performance improvements (7-22x faster according to benchmarks) by integrating a Zig-based HTTP core (turbonet) while maintaining full API compatibility. The framework uses a hybrid architecture where application logic remains in Python but network I/O, request parsing, validation, and optionally database operations are handled by Zig components. Key features include FastAPI-compatible routing and dependency injection, middleware support, WebSocket capabilities, OpenAPI automatic generation, and optional zero-Python execution paths for maximum performance. The project includes several reusable Zig libraries: dhi (validation), pg.zig (PostgreSQL client), metrics collection, and a high-performance radix trie router.
