An online tool that generates real-time railroad diagrams for your regular expressions to help understand their logic. It supports testing against text strings using JavaScript, Python, and PCRE engines.
What we love ❤️
- Instantly converts regex into visual railroad diagrams
- Supports JavaScript, Python, and PCRE flavors
- Real-time matching against test data
- One-click embedding for StackOverflow questions
Worth noting 💡
- Account required to save patterns and use unit testing features
- Interface is functional but looks slightly dated
Debuggex is a classic, highly effective tool for demystifying complex regular expressions. By visualizing the logic path, it makes debugging pattern matching significantly less painful than standard text-only testers.
