Build a free game with AI.

FreeGameStore is AI-first. Drop our SKILLS.md into your AI tool of choice, and the agent already knows the brand rules, the privacy mandates, the CLI, and the deploy flow before it writes a line of code. Ship a real, free, MIT-licensed game in an afternoon.

Even faster: connect the MCP server and build, publish, and improve games without leaving your editor — your AI writes the code (create_game → update_files), or the platform's VibeCode agent does (agent_build). One line to connect:

Workspace layout

Keep all your game repos under one folder so your AI agent finds them automatically:

mkdir -p ~/dev/fgs/games && cd ~/dev/fgs/games
~/dev/fgs/ games/ ← your game repos chess/ tetris/ racing/ platform/ ← store site & templates (maintainers only)

This matches the paths in SKILLS.md. For apps, use ~/dev/fas/apps/.

Or any other tool

Roo Code, Sweep, Open Hands, Smol Developer, the new Anthropic SDK agent — all of them work. The pattern is the same:

  1. Install the FreeGameStore CLI: npm i -g @freegamestore/cli then fgs login.
  2. Scaffold: fgs init my-game --template canvas.
  3. Tell your AI tool to read SKILLS.md. Drop the URL in the project's instruction file (CLAUDE.md, .cursorrules, .github/copilot-instructions.md, AGENTS.md, CONVENTIONS.md, system prompt, …).
  4. Build. The agent edits web/src/App.tsx and supporting files using the Shell layout, brand tokens, and brand fonts.
  5. Run fgs check. Compliance enforced.
  6. Run fgs publish. Provisions repo + hosting + DNS.
  7. Push to main. Auto-deploys in ~30 seconds.
The platform context lives at:
https://freegamestore.online/skills.md

Drop that URL in your tool's instruction file. The agent fetches it on demand and writes platform-aware code.

What "AI-first" actually means here

Three things, enforced by tooling:

The mandates aren't to slow agents down — they're to let agents go fast without breaking the platform.
