Question 1

How does the regex explainer work?

Accepted Answer

Paste your regular expression into the input field and the tool breaks it down token by token, explaining what each part of the pattern matches. It supports JavaScript regex syntax including flags, character classes, quantifiers, groups, and more.

Question 2

What regex flavors are supported?

Accepted Answer

The tool supports JavaScript-compatible regular expressions (ECMAScript). This covers most common regex patterns used in web development, including character classes, quantifiers, groups, anchors, lookaheads, and escape sequences.

Question 3

Can I test my regex as well?

Accepted Answer

Yes! You can enter a test string to see if it matches your regex pattern. The tool highlights matched portions and shows capture group results.

Question 4

Is this tool free?

Accepted Answer

Yes, completely free with no limits. All regex parsing happens in your browser — nothing is sent to any server.
