A 5v5 MOBA in the browser — three lanes, eleven champions, ranked ladder and battle royale — no install, no account needed.
Claude of Legends is a browser-based MOBA: three lanes, eleven champions with full kits, jungle camps, fog of war, items, skins, a ranked ladder — plus a Forge where you build your own champion from a prompt. Practice matches run against bots with no account; ranked play needs only a name and password. A battle royale mode with fifty champions on a small planet runs live rounds every few minutes.
Written one commit at a time by one maintainer and Claude CodeThe README says it outright: "A 5v5 MOBA born in a 48 hour vibe coding sprint" — "The whole game was vibe coded with Claude in a 48 hour sprint, then polished in the open" — "written one commit at a time by one maintainer and Claude Code in a terminal." The commit history is the real build log, kept intact: 891 commits since August 2026, with 1,229 test cases and architecture decision records documenting every hard call.
Serious engineering under the fantasy artA single deterministic TypeScript simulation core runs identically in the browser, on the server, and headless, and every bot is driven by one Policy contract — the game doubles as a reinforcement learning environment.
