## What it is
Woo is a fast, non-blocking HTTP server for Common Lisp built on top of libev, aiming to be among the fastest web servers in any language. It integrates with Clack/Lack applications and supports multi-worker clustering and SSL.

## Use cases
- serve HTTP requests from a Common Lisp web application
- run a high-performance non-blocking web server on libev
- deploy a Clack/Lack app in production
- run a multi-worker clustered web server
- serve HTTPS with SSL certificates in Common Lisp

## When to choose
- you are building web applications in Common Lisp with Clack/Lack
- you need a fast event-driven HTTP server on UNIX systems
- you want multi-worker clustering and graceful shutdown

## When to avoid
- you need a Windows server (UNIX only)
- you need production-grade stability (still beta quality)
- you are not using SBCL or Common Lisp

## Facets
- artifact type: library
- maturity: active
- function: http-server, web-framework, middleware
- domain: web-development, backend, apis
- platform: bsd
- tags: common-lisp, libev, non-blocking, clack, high-performance, ssl, linux, macos, web-server, docker
