Show HN: Server-rendered multiplayer games with Lua (no client code)
brunovcosta Sunday, January 04, 2026Hey folks — here’s a small experiment I hacked together over the weekend:
In short, it’s a way to build multiplayer games with no client-side game logic. Everything is rendered on the server, and the game itself is written as simple Lua scripts.
I built this to explore a few gamedev ideas I’ve been thinking about while working on Abstra: - Writing multiplayer games as if they were single-player (no client/server complexity) - Streaming game primitives instead of pixels, which should be much lighter - Server-side rendering makes cheating basically impossible - Game secrets never leave the server
This isn’t meant to be a commercial project — it’s just for fun and experimentation for now.
