Ultra-premium, local-first regex engineering studio. In-browser AST ReDoS complexity analysis, live in-situ capture visualizer, and curated 100-recipe production vault.
Safe Pattern: O(n) Linear Execution. No catastrophic backtracking risks detected in standard V8 / Python engines.
Engines utilizing Thompson NFAs (Rust `regex` crate, Go `regexp`, Google RE2) evaluate patterns in guaranteed linear time regardless of nested quantifiers.
Verify independently: Open DevTools > Network tab. Not a single byte or keystroke is ever transmitted to any server. Your proprietary logs, credentials, and regex expressions execute strictly inside your local browser memory.
