Terminal regex debugger with real-time matching, 3 engines, and plain-English explanations.

Desktopfreeglobal

rgx is a regex debugger for the terminal, offering step-through execution, ReDoS (catastrophic backtracking) analysis, three regex engines, code generation, and live stream filtering, with real-time matching, capture groups, and replace mode. It's built for developers on remote servers, in containers, or in air-gapped environments where opening a browser-based tool like regex101 isn't practical, and supports piping results into other commands.
