Patterns - The Regex App

By Nikolai Krill

Patterns is a simple yet powerful tool for working with regular expressions. Build great patterns quickly and effortlessly with syntax coloring, and with matching and replacing occurring in real time.

- See matches and replacements in real time while you edit your pattern.
- Copy match and replacement code snippets of your pattern for quick use in a number of different programming languages.
- The built-in regular expression reference sheet helps you find the piece of regex syntax you need.
