What Rustic does

Six notes on the launcher. They turn on their own: hover to pause, or move between them with the tabs and arrows.

Video (example data): search Explore for a mod and install it into the active instance.

Instances

Instances that just work.

Pick a Horizon build, add mods, packs and shaders: every download is verified before it touches your game.

rustic server · sandboxed plugins

A plugin can never crash the server: it is disabled with a log line, and the game goes on.

Robust where it counts.

Plugins run in a WebAssembly sandbox with fuel, memory and time limits. A trap, a panic or an infinite loop disables that plugin; the server goes on.

    • Every plugin runs isolated, in WebAssembly
    • Fuel, memory and time limited on every call
    • Error, panic or infinite loop: only that plugin is disabled
    • Updated and reloaded while the server runs
    See the sandboxHost a server

    • 0.37 µs for a host import round trip
    • 1.3 µs for a console command to a plugin
    • 21.3 µs for an event with 10 subscribed plugins
    • 180 ms cold compile, 0.24 ms from the cache
