OpenRegex

Self-hosted platform for testing regex across native engines with ReDoS protection and AI help.

Webfreeglobal

OpenRegex is a self-hosted platform for testing regular expressions against 15+ actual native engines — Python, RE2, .NET, Go, Java, Rust, and more — in isolated containers, guaranteeing results match production behavior rather than a single JavaScript approximation. It's aimed at developers who need accurate, engine-specific regex testing with built-in ReDoS protection, plus an optional AI assistant for generating and explaining patterns.
