An interactive regex tester with real-time highlighting, explanation, and a library of community patterns.
Regex101 makes regular expressions understandable. Paste a pattern and a test string, and it highlights every match in real time, step-by-step. The explanation panel walks through each token in plain English, so you finally understand what a terrifying pattern actually does. It supports multiple flavors — PCRE, JavaScript, Python, Go — and includes a quick reference and a community library of saved expressions. When a regex isn't doing what you expect, Regex101 shows you exactly why. It's the debugging tool every developer who writes regex should keep open.
