Diff Guru is a fast, powerful, and privacy-first online comparison platform designed to help users instantly detect differences across multiple file types with maximum accuracy and ease. Built for developers, designers, writers, students, QA teams, and business users, Diff Guru offers a complete set of comparison tools including Text Compare, Image Compare, PDF Compare, Excel/CSV Compare, and JSON Diff - all within a clean, distraction-free interface.
With Text and Code Compare, users can paste or upload content side-by-side and view highlighted differences in real time. Developers use it for code reviews, debugging, API response validation, and configuration tracking. Writers and editors rely on it to verify document revisions and content updates with precision.
The Image Compare tool allows users to visually detect pixel-level changes between two images, making it ideal for designers, QA teams, and digital auditors. The PDF Compare feature helps identify text and layout differences between two document versions. With Excel and CSV Compare, users can accurately track changes across spreadsheet files, while JSON Diff makes it easy to detect structural and value-based differences in API and configuration data.
One of Diff Guruโs strongest advantages is its privacy-first architecture. All comparisons run directly in the browser whenever possible, ensuring that sensitive data such as source code, business documents, and confidential records never leave the userโs system. There are no forced logins, no data tracking abuse, and no hidden uploads.
Diff Guru is completely free to use, requires no signup, and works smoothly across all modern devices and browsers. With its growing ecosystem of tools and resources, Diff Guru is not just a comparison utility - itโs a complete digital comparison workspace built for speed, accuracy, and trust.

Diffract's answer
Diffract is a purpose-built desktop diff tool that handles far more than plain text. A single app compares text, binary (hex view), images, PDFs, Word documents, Excel spreadsheets, ZIP/tar archives, and Git commits - all in a multi-tab interface. On top of the standard Myers diff, it offers Patience and Histogram algorithms per comparison, AST-based semantic diff that understands code structure (not just line changes), and automatic moved-block detection. It also runs fully headless as a CLI tool for use in CI pipelines.
Diffract's answer
Diffract is purpose-built, so it supports file types (PDF, Word, Excel, archives), workflows (three-way merge, Git browsing, semantic diff), and UX features (drag-and-drop, OS context menus, in-panel editing with undo/redo, minimap, search) that e.g. an IDE's diff panel simply doesn't cover.
Diffract's answer
Software developers and DevOps/SRE engineers who compare code, config files, and build artifacts daily. A secondary audience includes QA and release engineers who need to diff generated outputs and directory trees, and technical writers or analysts who compare Word documents, PDFs, or Excel exports without wanting a cloud-based or subscription tool.

I built Diff Guru to solve the privacy issue by making it 100% client-side with unlimited merge capabilities. But today, Iโm excited to announce a massive update: Language-Specific Syntax Highlighting. - Source: dev.to / 7 months ago
I faced this problem regularly while working on client projects and code reviews, which led me to create DiffGuru.com - a lightweight, privacy-first diff and merge tool built with React and Next.js that runs entirely in the browser. - Source: dev.to / 9 months ago
