Most standard regex patterns work. Lookaheads, lookbehinds, and backreferences are not supported in the generator. Patterns should be reasonably bounded - avoid unbounded quantifiers like * with no upper limit on long patterns.

Yes, each click generates new random strings. Character classes pick random characters from the allowed set, and quantifiers pick random counts within the specified range.

Quick Presets

Does this support all regex syntax?

The generator supports the most common JavaScript regex constructs: character classes ([a-z]), quantifiers (*, +, ?, {n,m}), alternation (a|b), groups, and common shorthand classes (\d, \w, \s). Very complex nested lookaheads or conditionals may not be supported.

Can I use this to generate realistic test emails?

Yes - use a pattern like [a-z]{5,10}@[a-z]{4,8}\.(com|net|org) to generate realistic-format (but fictional) email addresses for use in testing and seeding databases.
