I kept using the W3Schools "Try It" editor and similar tools, and every time it was slower, more ads, more bloat. So I built a clean replacement.

It's a single HTML file hosted on GitHub Pages. CodeMirror for syntax highlighting, combined or split HTML/CSS/JS tabs, dark/light mode, resizable panes, shareable links via URL hash. No server, no account, no tracking or cookies (just Plausible for basic traffic stats).

The plan is to add more tools over time (JSON formatter, regex tester, etc.) under the same idea — free, fast, no bloat.
