trystero
✨🤝✨ Build instant multiplayer webapps, no server required — Magic WebRTC matchmaking over BitTorrent, Nostr, MQTT, IPFS, Supabase, and Firebase
Project mention: I rebuilt my 2018 agar.io clone around real orbital physics, with no game server | dev.to | 2026-09-24I host on Vercel, and serverless functions (WebSockets included) don't keep every player of a room on the same instance. So I don't use them for the game at all. Whoever creates a room hosts the match in their own browser: the simulation runs in a Web Worker at 30 ticks per second, and everyone else connects over WebRTC. Signalling goes through public Nostr relays via Trystero, so the site stays fully static.

There's one more library I would like to point out by Margelo, react-native-filament. This library renders 3D graphics completely on native GPUs. So now it's quite possible to create a Pokemon GO like app in React Native.
