One app for mocks, webhooks, and API proxies
Stop switching between webhook.site, Postman mocks, and json-server.
API Dev Studio handles all three — offline, private, fast.
Coming soon for Windows, macOS, and Linux
Point your app at localhost:3456/api/users and get back whatever JSON you define. No server code needed.
Get a public URL that tunnels to your machine. See every Stripe or GitHub webhook in real-time.
Proxy requests to production, save the responses, replay them offline. Build against real data without hitting rate limits.
No cloud account, no data leaving your laptop. Works on a plane.
Native desktop app, not Electron. Starts in under a second, handles thousands of requests.
$49 one-time. No subscriptions. Free tier for personal projects.
Build UI before the backend exists. Define your own responses, test edge cases, work offline.
Test Stripe, GitHub, or Twilio webhooks without deploying. Debug locally with real payloads.
Join the waitlist. Early supporters get 50% off.
