API Mock Response Generator

Define your fields, pick a record count, and generate realistic fake JSON for prototypes, tests, and demos. Everything runs in your browser — nothing is uploaded.

Generated records appear here.

About this tool

Generates mock API responses from curated data banks — real-sounding first and last names (including Indian names), companies, and cities — so your prototypes look believable instead of being filled with foo and bar. Emails are derived from the generated names, IDs are sequential, and dates fall within the last year. Values come from Math.random: fine for static test data, not cryptographic.

Nothing you generate leaves the page — there is no server, no upload, and no tracking of tool inputs or outputs.
