Todroth: a 3D sandbox MMO for the browser built mostly with Claude

A small team built a browser 3D MMO with combat, ships, farms and guild sieges, using parallel Claude Code sessions to plan, build and test features.

The full story

Todroth is a 3D sandbox MMO that runs in a desktop browser, now in free beta. It has real-time combat, open PvP with a prison, ships, houses and farms, about 140 voiced quests, and guild sieges whose winners choose a King who can change the game world.

The developers describe what they want, often with a screenshot, and Claude plans, builds and tests it, sometimes making two versions to choose from. Each feature gets its own Claude Code session in its own git worktree, several at once, and Claude writes headless Playwright runs that sign up, play the prologue and take quests.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.
