Lancache

Self-Hosted

Open-source game download caching server to reduce LAN bandwidth usage

Overview

Lancache is an open-source caching solution optimized for game downloads, designed to cut network bandwidth costs for LANs, gaming cafes, or home networks. It caches files from 20+ game platforms (Steam, Epic Games, Origin, etc.)—so multiple users don’t re-download the same game files. Deployable via Docker for quick setup, it supports automatic cache cleanup, custom storage limits, and DNS redirects to route download requests. It reduces bandwidth usage by up to 90% and speeds up game installs/updates for local users.

Frequently Asked Questions

? Is Lancache hard to install?

Installation is straightforward using Docker (pre-built images are available), but it requires basic network knowledge to set up DNS redirects (to route game download requests to the Lancache server). Step-by-step guides in the official documentation simplify the process for beginners.

? Does Lancache work with all game launchers?

It supports most major game platforms, including Steam, Epic Games Store, Origin, Uplay, GOG, and Blizzard Battle.net. The community regularly updates the list of supported launchers, so check the documentation for the latest compatibility.

? Is Lancache completely free to use?

Yes! Lancache is open-source software licensed under the MIT License, meaning there are no upfront or recurring fees. You only need to cover the cost of hardware (server, storage) and electricity for hosting the cache.
