Show HN: Free API mock server from your OpenAPI spec (no sign-up)
ApiNotes Mock Server is a free, no-signup-required tool that generates live mock REST APIs from OpenAPI 3.0/3.1 or Swagger 2.0 specifications, with anonymous mocks expiring after 72 hours.
The goal was to remove all friction when you just need a mock API quickly:
No sign-up required to create an anonymous mock Supports paste, file upload, or URL fetch Produces a base URL + an auto-generated endpoints list Anonymous mocks currently expire after 72 hours (you can register to keep them / get higher limits) Link: https://apinotes.io/mock-server
I’d love feedback on:
What would make you trust a mock server like this for real projects? Any features you’d expect (auth simulation, latency/errors, stateful mocks, webhooks, etc.)? Is the 72-hour model reasonable, or should the free tier work differently? Thanks, happy to answer any questions and share implementation details.
