About This App
The Regex Tester helps developers test and debug regular expressions quickly and visually. Regular expressions are powerful but can be difficult to understand without seeing live results.
- Live Matching: Instantly highlights all matches in your test text.
- Flag Support: Toggle global, case-insensitive, and multiline modes.
- Error Detection: Invalid regex patterns are safely handled.
- Productivity: Save time while writing and debugging complex patterns.
This tool is ideal for developers, testers, and students working with validations, parsing, log analysis, or text processing.
