Best for

✓ Best for

Developers looking to deploy highly performant Python web applications with HTTP/2 support
Teams needing a drop-in replacement for Gunicorn with additional optimizations and features

✓ Best for

Teams building fast, asynchronous web applications with Python frameworks like FastAPI or Starlette
Developers needing a lightweight ASGI server for rapid development and deployment cycles
Projects requiring high performance and low latency in serving HTTP requests

Not ideal for

✕ Not for

Projects requiring cloud-hosted server solutions
Applications that do not require high concurrency or performance optimization

✕ Not for

Applications that require real-time streaming capabilities beyond what ASGI can offer
Teams looking for a full-featured web application framework rather than just an ASGI server
