serve-rs: A Gunicorn Replacement That won't make you cry
What is serve-rs?
Gunicorn served us well—until it didn’t. Between its million worker models, process juggling, and config gymnastics,
deploying a WSGI app often felt like a side quest. serve-rs changes that.
Built on Tokio and Hyper, serve-rs is a modern, Rust-powered WSGI server that’s:
✅ Simple – No more tweaking worker models for the nth time
✅ Effortless – Works out of the box with Django, Flask, and friends
And yes, ASGI support is on the roadmap—because it’s 2025, and WSGI alone isn’t cutting it anymore.
How It Works
- Rust-powered core – serve-rs uses Hyper for high-performance HTTP handling and Tokio for async scheduling.
- WSGI-compatible – Hooks into WSGI entry points, so existing apps work with zero changes.
- Planned ASGI support – Future versions will support ASGI frameworks like FastAPI and Starlette.

Why You’ll Never Look at Gunicorn Again
- No more endless worker models – You don’t have to Google "Gunicorn workers explained like I'm five".
- Processes? In 2025? – In the age of containers and serverless, why are you still micromanaging worker PIDs?
- Rust-powered speed – Because Python’s GIL has slowed you down enough already.
- Dead simple deployment – You don’t need an entire config file just to start your server.
- Works with Django – Because you already have enough problems dealing with it.
