Regex Tester
π§© Regex Tester β Real-Time Pattern Matching
Regular expressions (regex) are powerful tools used for searching, validating, and manipulating text using patterns. From validating email formats to parsing logs and extracting data, regex is an essential skill for developers and IT professionals. This live regex tester allows users to input a pattern, a sample block of text, and instantly see what matches β making it great for testing ideas or learning the syntax without needing an IDE.
This tool supports key regex flags like global (g), case-insensitive (i), and multiline (m) to mirror the behavior seen in JavaScript, Python, or command-line tools like grep and sed. Everything runs in your browser using native JavaScript regex logic, so you can test sensitive patterns without any data being sent to a server. Whether youβre a junior learning regex or a seasoned dev testing a complex validation rule, this utility has your back.
