Build and Test Regex
The Rule of Three: Gold, Silver, Bronze
Debug regular expressions without pulling your hair out. Following the rule of three, we've curated exactly three solutions: Gold, Silver, and Bronze picks.
The Rule of Three: Gold, Silver, Bronze
Following the rule of three principle, we present exactly three curated solutions for build and test regex.
RegExr
Learn, build, and test.
Real-time results, explanation of patterns, and community library.
Why I picked this:
RegExr is my favorite regex tool because it does three things perfectly: it shows real-time matches, explains what each part of the pattern does, and has a community library of common patterns. When I'm building a complex regex, the explanation feature helps me understand and debug my pattern. The community library has saved me from reinventing the wheel countless times. It's both a learning tool and a productivity tool.
Regulex
Visualize regex as a diagram.
Turns your confusing regex string into a clear railroad diagram.
CyberChef
The Cyber Swiss Army Knife.
For complex data extraction and manipulation involving regex and other operations.
