Frequently Asked Questions
Which Regex flavor is supported?
This tool uses JavaScript's built-in Regular Expression engine. It supports most standard regex features including lookaheads, non-capturing groups, and more.
Is it private?
Yes, entirely. Your text and patterns are processed locally in your browser and are never sent to any server.
Does it support global replacements?
Currently, this tool focuses on matching and highlighting patterns. We supply a simple 'Replace' tool separately if needed, but this explorer is for debugging logic.
