Regex Editor & Tester

This regex matches any line that begins with 'Feature: ' and is not immediately followed by one of the forbidden words 'Hatseflats', 'Bananas', or 'Frappadingue'. It is useful for validating or filtering feature titles in text, ensuring they don't start with banned names. The pattern uses a negative lookahead to exclude specific prefixes, while allowing all other feature descriptions.
