Why DevTools?

Most online tool sites are bloated with ads, force sign-ups, or send your data to a server. DevTools is different: every tool here is open, fast, and privacy-friendly. JSON formatting runs entirely in your browser. AI-powered tools call a model API only when needed, and your inputs are never stored.

Built by a developer, for developers. If there is a tool you wish existed, tell us about it.
