Regex Tools

Test regular expressions with match, replace, and extract modes. Configure flags, view match positions and capture groups, and debug patterns — uses JavaScript regex syntax; blocks some risky patterns but is not a full ReDoS guard.

Regex Tools

• Regex Tester

  Test regular expressions against sample text. Match finds patterns with positions, Replace substitutes matches (use $1, $2 for capture groups), and Extract lists all matches. Complex patterns on very long input may still be slow.

• Glob Pattern Tester

  Enter a glob pattern in Tool Settings and paste sample paths (one per line) in Input. Supports *, **, and ? — not brace expansion, character classes, or full .gitignore rules.
