RegEx Playground

This page can be used to check regular expressions with strings specified by the user. The top text area is where the user should enter the regular expression, while the bottom area is where the strings to check should be entered. If the given regular expression matches a line, a plus sign is shown next to it, while if it does not match it, a minus sign is shown. Empty lines are omitted.

Strings are separated with newlines, so multi-line matching is not supported. Only regular expressions with ECMAScript syntax are supported.
