Rune
What Rune is
Rune is a social gaming app for playing multiplayer HTML5 games together with voice chat. For developers, it handles game hosting, accounts and friends, matchmaking, spectating, and resolving conflicts or version mismatches. Games can be built with web frameworks such as React, Svelte, Vue, r3f, and PixiJS, then run in the Rune app’s WebView. Rune runs game logic on servers and uses predict-rollback to synchronize play without requiring developers to write game networking code. Supported examples include board, sports, co-op, strategy, simulation, physics-based, party, and arcade games. Developers can start a project with `npx rune@latest create` or add the SDK manually; the documentation recommends a template with Rune-specific ESLint and Vite plugins. Game logic must use a subset of JavaScript, actions must be synchronous and take under 10 ms, and memory use must stay under 1 MB. Uploaded games should be under 25 MB unzipped. Rune is free for players and developers, including game hosting, and is available on iOS and Android.
