Framework
OpenParty
A flexible, modern, TypeScript-first framework for building party games.
OpenParty is a TypeScript framework for multi-device party games: the game runs on a TV-connected PC while the host and players join from their phones.
It ships with four reference games, all built only on the framework’s packages:
WitClash · 3–8 players
The full reference game: rules, browser UI, bots, terminal client and content.
Bluff · 3–8 players
Browser UI, bot kit, demo tables and a terminal client.
Crew · 3–5 players
Headless rules only: an asymmetric co-op guess-the-sum game.
Rush · 2–8 players
Headless rules only: a tap race driven by the server tick.
How it works
One command launches a game:
bun run launch wit-clashThat opens the host page, and players join with a room code. Bots can fill empty seats and play by themselves, and games with a terminal entry can be played at a prompt or watched as an all-bot demo.
Under the hood the framework is split into small packages — the Colyseus-free runtime, the Colyseus host, a Svelte 5 client SDK, generic viewmodels and components, a bot kit, terminal clients, and a launcher that runs the server, code API, client, bots or demo as one process group. Tests enforce 100% coverage.
