RegexPal: Free Regular Expression Tester & Visualizer

Test, analyze and visualize regex patterns with RegexPal, a free tool for learning and debugging regular expressions.

What is RegexPal?

RegexPal is a free web-based application for testing, analyzing and visualizing regular expressions. It provides an intuitive graphical interface that allows users to easily enter a regex pattern on one side and sample text to test it against on the other.

As you type the regex, RegexPal dynamically highlights matching parts of the test string in different colors, allowing you to visualize how the expression works. It also displays detailed info like capture groups at each step. This makes it much easier to build, test and troubleshoot even complex regexes.

RegexPal has handy features for regex learning like reference sheets, regex syntax highlighting, bookmarking, shareable permalinks and search. The analysis view provides detailed step-by-step explanation of how the regex matches the input text. These make RegexPal a great tool for both learning and debugging regular expressions.

It runs fully client-side inside the browser, requires no account signup and all data stays local. RegexPal supports JavaScript, Python, PHP and Perl regex dialects. The tool is completely free to use with no ads or rate-limits.

Clunky and Unreliable for Real Testing

RegexPal is frustratingly slow, especially with complex expressions—it often freezes or times out. The visualization is basic and doesn't help much with debugging nested groups, and the lack of advanced options makes it feel outdated compared to other free tools.
