DIffEasy
Compare text & code side-by-side — 5 versions, no uploads
Compare text, code, and documents side-by-side entirely in your browser. Supportsup to 5 versions simultaneously, interactive change logs with auto-scroll, word count tracking, and monospace font rendering for code. Perfect for developers, writers, and legal reviews. No uploads. No servers. No sign-up.
a tool I built because comparing text and code shouldn't require uploading sensitive data to sketchy servers.
The problem: Every time I needed to compare two versions of code, a document, or legal text, I had to use online diff tools that uploaded my data to servers. Codebases, legal clauses, confidential documents - sitting on someone else's infrastructure. Not okay.
And the ones that claimed to be "secure"? They still transmitted my data.
The solution: A diff checker that runs 100% in your browser — with developer-grade features:
🔄 Multi-Version Comparison — Compare up to 5 different text versions simultaneously. Dynamically switch between any pairing as your base and comparison.
📊 Interactive Change Logs — See exactly where lines were added (+) or removed (-). Click any entry and your view smoothly scrolls directly to that exact line edit.
📝 Word Count Tracking — Track added and removed words instantly. Perfect for writers tracking edits and revisions.
💻 Code-Friendly Rendering — Renders text using monospace fonts and handles all indentation, HTML characters, and script blocks cleanly.
⚡ Ultra-Fast Client-Side Processing — Built with native vanilla JS. No server queues. No upload time. Instant results.
🛡️ 100% Private — Your text and code never leave your device. No uploads. No servers. No tracking.
📶 Works Offline — Once loaded, the tool works completely offline. All operations are written in native vanilla JS running inside your browser.
🆓 100% free — No limits. No watermarks. No sign-up. No "upgrade to pro."
Who is this for?
Developers reviewing code refactors and pull requests
Writers tracking document edits and revisions
Legal professionals comparing contract clauses
Anyone comparing text, code, or documents who values privacy
The key insight: Most online diff tools upload your data to servers. We don't. We literally can't access your data because it never leaves your browser. That's the difference between a privacy policy and privacy by architecture.
I'd love your feedback! Try it out and let me know what you think.
