Hey Product Hunt 👋 I built Ghost Regex because I kept jumping between my editor and browser tabs every time I needed to check a regex. Open tab, paste pattern, test on made-up strings, copy back. An hour later — same loop. It was killing my flow. So I made the whole thing live inside VS Code: — Railroad diagrams that show the structure visually — A ReDoS detector that catches nested quantifiers before they hit production, with an auto-fix — Preview on real files: point at an actual file, type a pattern, see matches highlighted in the content. No dummy strings. — 94 built-in snippets, code gen for 5 languages, unit tests for regex The Free version is fully functional — no trial, no limits. Pro is $6/mo for anyone who needs Preview, unit tests, and the full snippet pack. I'd love honest feedback, especially if something feels off or could work better. Thanks for checking it out 🙏
