Product summary

Review the store description, core capabilities, and common use cases.

Regex Lab is a lightweight, offline regular-expression tester built for clarity and speed. Enter a pattern, pick flags (i, g, m, s, u, y), paste test text, and see live highlighting, match counts, execution time, capture groups, and an optional Replace preview (supports $1, $2, …). You can copy the highlighted HTML or copy the replaced output in one click.
