RegexCraft vs Regulex

RegexCraft is a desktop workbench for testing, replacing, comparing, debugging, and generating regular expressions. It supports .NET, PCRE2, and JavaScript with full fidelity; other listed flavors have High or Approximate fidelity. Match mode highlights matches and capture groups, while Replace mode previews substitutions and supports backreferences. Compare mode puts results from two to four flavors side by side, showing validity, matches, groups, fidelity, and known differences. Its educational step-through walkthrough covers the .NET engine using F10 and F11. A GREP tool searches and replaces across folders with include and exclude globs, cancellation, dry-run, and backups. It can generate code snippets for languages including C#, JavaScript, Python, Go, and Swift. Library, history, and settings stay in the operating system's application-data folder; the core product has no account system or cloud sync. Personal use is free. Commercial, organizational, government, or revenue-generating use requires a $49.00 USD one-time Business license.
