OpenRegex

A unified, self-hosted platform for testing and debugging regular expressions. OpenRegex uses isolated polyglot micro-workers to guarantee 100% native engine consistency, featuring ReDoS protection, real-time analysis, and an AI-powered assistant. Maintained by SunneV on GitHub, where it has earned 82 stars from the community.

It's actively developed around ai-assistant, debugging-tool, developer-tools, and is a solid reference for anyone building with these tools.
