RegexForge

Build, test, and debug regular expressions with visual pattern matching

Code & DevelopmentFreemium

RegexForge provides an interactive visual environment for constructing regular expressions, showing real-time match highlighting, capture group visualization, backtracking step counts, and catastrophic backtracking warnings. The tool generates regex patterns from plain-language descriptions and provides equivalent patterns across regex flavors including PCRE, JavaScript, Python, and Go. Developers use it to build complex patterns without trial-and-error while code reviewers use it to verify that regex patterns in PRs behave correctly on edge cases.
