## What it is
Polipo is a lightweight, single-threaded, non-blocking caching HTTP proxy written in C with very modest resource needs. The project is no longer maintained, with the last release in 2017.

## Use cases
- cache web traffic on a low-resource machine
- run a local HTTP proxy to speed up browsing
- share a caching proxy across a small LAN
- reduce bandwidth usage by caching repeated requests
- use a simple forward proxy for privacy filtering

## When to avoid
- you need a maintained proxy with security updates
- you need modern proxy features like HTTPS interception or HTTP/2
- you're starting a new project - use Squid, Tinyproxy, or Privoxy instead

## Facets
- artifact type: service
- maturity: abandoned
- function: proxy, caching, http-server
- domain: networking, privacy, web-development
- platform: windows, cross-platform
- tags: http-proxy, web-cache, c, lightweight, linux, macos
