JSON Formatter & Regex Tester–Free Tools

Format JSON, test regex, and debug faster in your browser.

What it does

I built two simple, fast developer tools to remove friction from everyday debugging. JSON Formatter & Tree Viewer lets you format, minify, and explore large JSON with an interactive tree — all 100% client-side, so your data never leaves the browser. Regex Tester & Explainer offers live matching, highlights, 100+ ready-to-use regex patterns, and clear explanations for beginners and advanced users. Built for developers who value speed, clarity, and privacy. Feedback is very welcome 🙌
