What is MockBolt and how does it replace json-server?

MockBolt is a free, browser-based tool that generates live mock API endpoints from pasted JSON—no installs or signups needed. It beats json-server by offering instant public URLs, CORS, delays, and status codes without local setup.

Does MockBolt require an account or payment?

Nope—fully anonymous, free for 24 hours per mock. No email, no card. Management via secret URL only.

Can I use MockBolt for team collaboration and testing?

Absolutely. Share public URLs with teammates; edit privately anytime. Supports all HTTP methods, custom headers, and OpenAPI imports for complex mocks.
