🖥️ Corbsy Desktop
Use your existing AI subscriptions
Direct an AI team to build your game. The desktop app uses your Claude Pro, ChatGPT Plus, or Gemini subscriptions for AI — no API bills.
We couldn't detect your OS — see other downloads below.
Why the desktop app?
The web version uses pay-per-token API keys for Claude / OpenAI / Gemini. Heavy users can spend $100–$200/mo on API alone.
The desktop app shells out to your locally installed claude, codex, gemini, or hf CLIs. Your Claude Pro ($20/mo) or ChatGPT Plus ($20/mo) covers usage. No API bills.
What you'll need installed
Install at least one of these CLIs and log in with your existing subscription:
- Claude Code —
npm i -g @anthropic-ai/claude-code - OpenAI Codex —
npm i -g @openai/codex - Gemini CLI —
npm i -g @google/gemini-cli
None installed? The desktop app still works — it just falls back to API key paste for those providers, same as the web version.
⚠️ First-run warnings (we'll explain them)
- Windows SmartScreen says "Microsoft Defender SmartScreen prevented an unrecognized app from starting"
- The installer isn't code-signed yet. Click More info → Run anyway. You only see this on first launch.
- macOS says "Corbsy Studio is damaged and can't be opened"
- Same reason — unsigned installer. Right-click the app → Open → Open in the confirmation dialog. You only see this on first launch.
- The app opens, but says "demo mode" not "Desktop mode active"
- No CLI was detected on your PATH. Install at least one of the above and re-open the app.
