Editorial interest 78/100 Selection signal · not a rating of the site

A browser-based regular-expression workbench for matching, debugging, explaining, sharing, and generating code from regex patterns.

Landing page captured for the 2026-09-14 issue.

Field notes

The workbench accepts a pattern, flags, and test string, then exposes matching, explanation, substitution, code-generation, and export views. Its linked validators focus on concrete cases such as RFC 5322-style email checks, URL components, E.164 phone numbers, password lookaheads, and Java or .NET flavor differences. The page says sharing encodes the exact setup in a URL and describes ReDoS detection as heuristic analysis of dangerous pattern structures.
