## What it is
Japronto is a screaming-fast asynchronous HTTP toolkit with an integrated pipelining HTTP server for Python 3.5+, implemented in hand-tuned C on top of uvloop and picohttpparser. It remains an early alpha preview with provisional APIs, receives no active development (though not formally abandoned), and explicitly warns against production use.

## Use cases
- build a high-performance http server in python
- handle millions of requests per second with python
- fast asyncio web framework for hello-world benchmarks
- pipelining http server based on uvloop
- serve http faster than go stdlib from python
- minimal async http toolkit for speed enthusiasts

## When to choose
- You need maximum raw HTTP throughput in Python and are comfortable with C-level plumbing and alpha-quality APIs
- You want to experiment with pipelined request parsing and uvloop-based asynchronous I/O
- You are benchmarking Python HTTP servers against Go or Node.js implementations

## When to avoid
- Any production or serious use - the project is alpha quality with provisional APIs and explicitly warns against production deployment
- You need a stable, well-maintained framework with an ecosystem - consider aiohttp, Starlette, or FastAPI instead
- You are a novice Python programmer or uncomfortable working with C extensions
- You need long-term support, new features, or Windows support - development has stalled and uvloop targets Unix-like systems
