regexdev - regexdev : Visualizer&Debugger and Editor for regex

I'm excited to share regexdev – a visualizer, debugger, and editor for C#-style regular expressions that makes regex actually *visible* and *understandable*. What sets it apart? - 🌳 AST-based visualizer – see the hierarchical structure of your pattern instantly - 🐛 Step-by-step debugger – watch the matching engine execute one step at a time - 📍 Breakpoints – pause execution at any point to inspect internal state - ✅ Continuous verification – matching results are validated against the official C# regex engine, with warnings if anything differs - 🔧 Full support for advanced features like balancing groups The parser is open source under the MIT license, and the full tool is actively being refined. Whether you're a developer debugging complex patterns, a teacher demonstrating regex concepts, or a student trying to understand how regex engines really work – regexdev turns regex from a black box into a transparent, debuggable experience. Try it now at www.regexdev.com, and check out the repo: github.com/longxya/regexdev. I'd love to hear your feedback – let me know what features you'd like to see next!
