RegexRegex vs Retest
Both stand on regular expression testers. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Web
RegexRegex offers local JavaScript testing alongside guided pattern building, saved test cases, and replacement previews. Checks using other listed engines require an explicit online run, and the builder is not a full visual representation of every regex.
