Description
Railroad diagrams, Explain with AST, ReDoS detector, unit tests, and Preview on real files — all in one VS Code extension. The unique part: point it at an actual file, type a regex, see matches highlighted in the content. Plus a ReDoS detector that catches nested quantifiers and suggests a fix: (a+)+$ → (a+)$. 94 snippets, code generation for 5 languages. Free is fully functional, Pro is $6/mo.
