Tinyproxy

Tinyproxy is a lightweight HTTP/HTTPS proxy daemon for POSIX systems, designed to run with minimal memory and CPU usage. It buffers high‑speed server responses and relays them at the client’s maximum rate, reducing perceived sluggishness on shared Internet connections. The daemon can operate in forward, transparent, reverse, and upstream modes, and supports HTTPS tunneling via the CONNECT method.

The software targets environments where resources are limited, such as embedded devices, older machines, or network appliances like Linux‑based routers. Configuration options allow filtering of domains and URLs, addition of custom headers, and access control based on subnets or interfaces. It can be run as an unprivileged user to lower security risk, and provides remote statistics for monitoring proxy load.

Tinyproxy’s source follows a simple, KISS‑style design and is distributed under GPL‑2.0, making it free, open‑source, and self‑hostable. It builds with a standard GNU configure script and can be extended through optional compile‑time features such as XTinyproxy headers and filtering support.
