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/awaitsupport 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.
🛠️ Quick Start
📦 Install
pip install bustapi
📍 Your First App
from bustapi import BustAPI
app = BustAPI()
@app.route("/")
def hello():
return {"message": "Hello, BustAPI!"}
