If you’ve ever wanted the simplicity of Flask with the raw speed of a compiled language, BustAPI is here to deliver just that — and then some. Built with Rust under the hood but designed for Python developers, BustAPI brings blazing-fast performance without sacrificing the developer experience.

🧠 What Is BustAPI?

BustAPI is a modern Python web framework powered by Rust via PyO3 bindings and the Actix-Web engine. That means your Python code runs with compiled-speed performance — tens of times faster than traditional Python frameworks — while keeping the same expressive, Python-friendly syntax you already know.

BustAPI feels like Flask/FastAPI but runs like a compiled binary under the hood — a combination you didn’t know you needed.

⚡ Why BustAPI Matters

🏎️ Blazing Performance

• Leverages Rust’s Actix-Web runtime for truly fast request handling.
• Benchmarks show up to 50x+ faster throughput than Flask and large gains over FastAPI.
• Optimized for high-throughput APIs, microservices, and concurrent workloads.

🐍 Python-First Developer Experience

• Flask-compatible API, so you can migrate or start fresh with minimal learning curve.
• Native async/await support for modern Python concurrency. (grandpaej.github.io)
• Auto-generated OpenAPI/Swagger docs on demand.
• Full type hint integration and request validation.

📦 Flexible & Production-Ready

• Works with popular deployment tools like Gunicorn, Uvicorn, and Docker.
• Supports templating (Jinja2), middleware, rate limiting, and more.

* Edge and cloud deployments are supported thanks to its performance and portability.
