When to use this in your project
Populating a development database
Generate realistic user records, orders, or transactions to make the UI look like real production data during development.
Writing integration tests
Use mock responses to test your API client code without depending on a live backend.
Load testing before launch
Generate a k6 or Artillery script to stress-test your endpoints before production traffic hits.
Developer notes
!Mock data should resemble production data in shape but must never contain real user PII.
!Run load tests in a staging environment only — running against production will affect real users.
!Edge cases to always test: empty input, null values, max-length strings, Unicode characters, negative numbers.
Privacy & Security
All Dev-Belt tools run 100% in your browser using client-side JavaScript. Your input data is never sent to our servers, never logged, and never stored. This includes code snippets, credentials, tokens, API keys, and any other sensitive information you enter. We only track authentication events for account management — never tool usage, search queries, or input data.
