## What it is
Ferron is a fast, memory-safe web server written in Rust with automatic TLS certificate management via Let's Encrypt. It offers static file serving, reverse proxying with load balancing and health checks, and simple KDL-based configuration with secure defaults.

## Use cases
- serve a static website with automatic https
- reverse proxy for backend apps with load balancing
- self-host a website with free tls certificates from lets encrypt
- replace nginx or caddy with a simpler rust web server
- host multiple sites on one server with per-host configuration
- set up a production web server in minutes with docker
- serve static files with precompression and caching

## When to choose
- you want automatic TLS with zero manual certificate setup
- you prefer simple, readable configuration over nginx-style directive sprawl
- you need a memory-safe, high-performance server for static sites or reverse proxying
- you want a modern alternative to Caddy or nginx with packages for Debian, RHEL, Windows, and Docker

## When to avoid
- you need an extremely mature ecosystem with decades of community modules like nginx or Apache
- you require advanced features only available in beta (Ferron 3 is pre-release)
- you depend on complex third-party module ecosystems or .htaccess-style per-directory configs
