Trustworthy ReDoS (regex denial-of-service) vulnerability checker.

Desktopfreeglobal

recheck is a free tool that analyzes regular expressions in JavaScript and Scala, offered as a command-line tool, a library and an ESLint plugin. It identifies expressions prone to catastrophic backtracking so teams can detect ReDoS vulnerabilities before code ships; it is aimed at developers who work with regex-heavy code and is maintained on GitHub.
