Local API sandbox for AI coding agents. Agents write Stripe/Twilio/GitHub/OpenAI code — then run it on live keys. GhostAPI gives provider-shaped APIs on 127.0.0.1, a live traffic dashboard, MCP controls, chaos mode, and secret masking — without touching prod. npx @yiaany/ghostapi start --open
Hey Product Hunt 👋
I built GhostAPI because coding agents don’t just suggest integrations anymore — they run them.
That usually means real Stripe calls, real Twilio SMS, real GitHub writes, and real OpenAI spend… often before you’re ready.
GhostAPI is a local API world on 127.0.0.1:
• provider-shaped endpoints (Stripe, OpenAI, Twilio, GitHub, Discord, Resend…)
• live dashboard for traffic + replay
• MCP tools to inspect state, force responses, and turn on chaos mode
• secret masking
• one-command setup for Cursor / Claude / other MCP clients
Try it:
npx @yiaany/ghostapi start --open
Site: https://ghostapi-virid.vercel.app/
GitHub: https://github.com/yiaany/ghostapi
Would love brutal feedback:
1) Which provider should be highest fidelity next?
2) What’s missing for your agent loop?
3) Would you run this in CI?
I’ll be here all day — ask me anything.
