Regex Tester Online Free — Test Regular ExpressionsTest and debug regular expressions against sample text online for free. See live highlighted matches, group captures, and match count. Supports.How to use Regex Tester — step by step

Enter your regex pattern — Type your regular expression in the pattern field (without the surrounding slashes). Set flags as needed: "g" to find all matches (not just the first), "i" for case-insensitive matching, "m" for multiline mode. Common uses: validating email or phone number formats, extracting data from log files, finding and replacing patterns in text, or testing a regex before adding it to your code.

Paste your test string — Add the text you want to match against in the input area below. All matches are highlighted in real time as you type your regex — no button press needed. Capture group values appear in the match list below, labelled by group number or name.

Refine until correct — Adjust your regex in the pattern field and watch the highlights update instantly. When you have the right pattern, copy it to use in your JavaScript, Python, Java, or any other language that supports ECMAScript-compatible regex. Completely free, no signup.

Frequently asked questionsHow do I test a regular expression against text online?Enter your regex pattern at tools.arkaserve.com/regex-tester, paste your test string below it, and all matches are instantly highlighted in real time. Capture groups are listed with their matched values. Use the "g" flag for global matching (all matches) and "i" for case-insensitive. Works with JavaScript ECMAScript regex syntax, compatible with most programming languages. Completely free, no signup.Why is my regex not matching anything?Common reasons: missing the "g" flag (without it only the first match is found), incorrect escaping (in a regex tester you type \d not \\d), a quantifier that is too strict (use \d+ instead of \d for one or more digits), or a character class that is too narrow. Check the flags panel and try simplifying your pattern first — start with a partial match, then add specificity.Can I use capture groups and named groups in the regex tester?Yes. Both numbered groups (\d{4}) and named groups (?<year>\d{4}) are supported. Matched values for each group appear in the match results list below the test string. Named groups are listed by their name (e.g., "year: 2024"), numbered groups by their index. Use the "g" flag to see all matches, not just the first.
