RelayKit

A tiny, dependency-free toolkit for running a self-hosted file relay on a single small server.

RelayKit accepts uploads over HTTPS, stores them in a local content-addressed pool, and hands out short-lived download links. It is designed for people who occasionally need to move files between their own machines without signing up for a third-party service.

Features

• Single static binary, no database, no external dependencies
• Content-addressed storage with automatic deduplication
• Expiring share links (1 hour to 30 days)
• Optional per-link password and download limits
• Runs comfortably in 64 MB of RAM

Quick start

$ relaykit serve --listen 127.0.0.1:7310 --data /var/lib/relaykit
$ relaykit push ./report.pdf
