RegexCraft vs RegexPilot

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.

RegexPilot is a Mac-native visual regular-expression builder with AI for composing, inspecting and testing patterns. Users assemble expressions from categorized drag-and-drop blocks, inspect them in a panel and follow a plain-English breakdown tree linked to the pattern. Sample text shows highlighted matches and capture groups, and replacements can be assembled from blocks. The product supports 21 regex flavors and routes patterns to the corresponding language engines. Users can provide API keys for listed AI providers or run AI offline with LM Studio, Ollama, llama.cpp or LocalAI. Its library includes 50 curated patterns and supports folders, tags and JSON import/export. A VS Code extension synchronizes changes between the app and regex literals in the editor. Users can export code for 21 languages, create SVG or PNG railroad diagrams and make browser-openable share links. The desktop app says it sends no usage statistics, telemetry or analytics to a server on its own; patterns and settings remain on-device unless a share link is created. It requires macOS 14 or newer. The free plan covers JavaScript and TypeScript engines; the one-time license costs 19.00 EUR.
