RegexCraft
RegexCraft is a modern, cross-platform tool that treats regex as first-class craft — testing with real engines, honest multi-flavor fidelity, GREP for whole trees, code generation you can paste into production, Compare and Debug panels, and Export for match results — without leaving the desktop.
