Regex Tester Pro is a Chrome extension for writing, checking and learning regular expressions. It highlights matches in a test string as the pattern is edited and displays a validation status. Users can save expressions in a categorized library for later matching, replacing or study, and consult step-by-step explanations to understand how patterns work. It is intended for learners and anyone who needs to test or reuse regex patterns. The extension runs on Windows 10 and Windows 11.

Regex Tester Pro is a Chrome extension for writing, checking and learning regular expressions. It suits beginners who want immediate feedback while building a pattern, as well as users who need a quick way to validate expressions against sample text. Its workspace brings the pattern and test string together so their relationship can be reviewed as the expression is edited.
Live highlighting updates as the pattern and sample text are entered. This makes it easier to see which parts of a test string match and to spot problems without repeatedly running a separate check. The extension also shows a validation status after entry, helping users confirm whether a pattern works with the current test case before putting it to use elsewhere.
For ongoing work, Regex Tester Pro includes a library where expressions can be added and retrieved later. Entries can be classified by purpose and used for matching or replacing, or revisited as learning examples. Keeping commonly used patterns in one place can reduce repeated typing and make it easier to compare or reuse expressions across tasks. The extension also provides step-by-step explanations to help users understand how patterns are interpreted and identify areas that may need correction.
Typical uses include learning regular-expression syntax, checking whether a pattern finds the intended text, debugging a pattern as it is written, and retaining reusable expressions for matching or replacement. A focused tester can help catch errors early, but results depend on the pattern and the sample text supplied; users should verify expressions against representative data before relying on them in a larger workflow.
Regex Tester Pro runs as a Chrome extension on Windows 10 and Windows 11, including 32-bit and 64-bit Windows 10 systems. It is distributed as a demo. Its small installation package is suited to users who want a browser-based environment for testing and organizing regular expressions rather than a standalone development suite.
