Regex for email and URL matching
Get reliable patterns for the classic hard cases — emails, URLs, phone numbers — with the trade-offs spelled out so you choose the right strictness.
Matching emails and URLs with regex is famously a trap: the fully-correct email pattern is monstrous, and the short one everyone copies rejects valid addresses. The right answer depends on whether you want strict validation or a loose pre-filter.
This tool gives you a pattern fit for your purpose and explains the trade-off, so you knowingly pick the level of strictness you need rather than copying a pattern with hidden gaps. For email, it can also pair with a dedicated email validator when correctness really matters.
