Spin up a custom endpoint to test HTTP requests, inspect every inbound call, and (optionally) mock an entire OpenAPI document in seconds. No sign-up, no cost.
Visit mockbin.io, create a bin, and start sending requests to your new endpoint.
Send any HTTP method to the URL you get back:
curl -X POST https://api.mockbin.io/<bin-id> \
-H "Content-Type: application/json" \
-d '{"hello":"world"}'Then watch incoming requests live from the bin detail page.
At Zuplo we were big fans of mockbin.org and used it for testing APIs and doing demos. Unfortunately, it was shut down.
In the spirit of being scrappy and shipping quickly, a group of us built a replacement as an impromptu hackathon project on a weekend — and we shipped with love ❤️ and a bit of coffee ☕️.
The API is built with Zuplo and stores bin data in Cloudflare's R2 (or any S3-compatible storage).
The frontend is a Next.js app under www/ deployable on Vercel or anywhere else you prefer.
