TxtCmp

TxtCmp is a free, browser-based diff tool with no file size limits, ensuring privacy by processing files entirely client-side. It offers merge mode for conflict resolution, regex search, change type filtering, keyboard shortcuts, and export options to Markdown/HTML. It supports split/unified views, syntax highlighting for over 18 languages, and dark mode. Built with vanilla JavaScript, jsdiff, and Prism.js, and hosted on Cloudflare Pages, TxtCmp is ideal for developers, writers, and data analysts. Future plans include shareable links, light mode, Git integration, an API endpoint, a CLI tool, and a VS Code extension.
