Hey hunters 👋
I built Mock and Match because every time I needed realistic-but-fake data to test a form (a valid-looking CPF, a working UUID, a fake-but-formatted credit card), I ended up either hand-writing fixtures or fighting some clunky tool that wanted my email or an account first.
So it's: a schema builder for mock/test data (CPF/CNPJ with real check-digit validation, credit cards, emails, dates, 50+ field types), plus a JSON ↔ TypeScript/Zod/YAML/XML converter and a JSON formatter — all running 100% in your browser, nothing ever touches a server.
Free, no signup. Would love your feedback — especially which field types or conversions you'd want next.
