## What it is
Thin is a small and fast Ruby web server for Rack applications, runnable via a CLI with configuration files and daemonization support. It was archived in 2025 after 20 years and is no longer maintained, with Falcon recommended as its successor.

## Use cases
- serve a rack application in ruby
- run a rails app behind a fast web server
- daemonize a ruby web server with pid and log files
- configure a ruby app server via yaml config
- replace webrick with a faster rack server

## When to choose
- maintaining a legacy ruby app already using thin
- you need a tiny, fast rack server on old ruby versions

## When to avoid
- starting a new ruby project - use Falcon, Puma, or another maintained server
- you need long-term security support or active maintenance

## Facets
- artifact type: library
- maturity: abandoned
- function: http-server, web-framework, cli
- domain: web-development, backend, developer-tools
- platform: ruby, cli
- tags: rack, rails, web-server, archived, mongrel-parser
