We made an open-source LanCache app with cache browsing, cleanup and live activity

We've been running LanCache on our TrueNAS server and had about 3.4 TiB of cached data. We wanted a practical way to see what was in it and manage the space, so we built Super Lan-Cache. The source and install files are now public: https://github.com/HDR-Performance/super-lan-cache

It combines the LanCache engine and a web UI in one container. It scans an existing cache, shows cache hits and live activity, groups indexed files by service or Steam depot, and previews selected cache groups before you remove them. Cache allowance and retention settings can be changed from the interface. We've been testing it at home with Steam downloads, including Turok 3 and ARC Raiders.

For a group of PCs downloading the same supported content, the benefit is being able to reuse cached data over the LAN and see whether requests are actually hitting the cache. It doesn't make the first download magically faster. It also can't guarantee that a whole game is cached just because a depot appears in the library, and HTTPS content stays uncached.

We also published Super Pi Hole, our separate Pi-hole v6 build with a custom DNS and device interface: https://github.com/HDR-Performance/super-pi-hole. You can optionally pair the apps with a setup code and review a Steam or other cache DNS preset. Super Lan-Cache works without it, so you can keep your own DNS setup.

Both are free, open source and currently early test releases, with Docker Compose and TrueNAS installation YAML. These screenshots are from our running server; the cache screenshot still uses its earlier LanCache Control name. I'd be interested in feedback from people managing a cache for LAN parties, especially how you decide what to keep between events.
