DiffBoard
Compare code, JSON & text with visual diffs
A developer-friendly code comparison tool.DiffBoard is a modern Chrome extension that helps developers compare code, JSON, logs, configs, and text with GitHub-style visual diffs. Drag & drop files, search within diffs, export results, ignore whitespace changes, and switch between side-by-side or unified views. Built for speed, privacy, and productivity — fully offline with no tracking or external servers.
👋 Hi Product Hunt!
I'm Kartik, the maker of DiffBoard.
As a developer, I constantly found myself comparing code snippets, JSON payloads, API responses, logs, and configuration files. Most online diff tools either felt outdated, lacked useful workflow features, required uploading data, or weren't optimized for day-to-day developer use.
That's why I built **DiffBoard** — a modern, privacy-first Chrome extension for comparing code, JSON, text, logs, and configuration files directly in the browser.
✨ Some of the features included in the current release:
• Side-by-side and unified diff views
• GitHub-style visual diff rendering
• Drag-and-drop file comparison
• Search inside diffs with match navigation
• Copy and export diff results
• Ignore whitespace, case, and line-ending differences
• JSON formatting and validation tools
• Session recovery and keyboard shortcuts
• Fully offline with no tracking or external servers
Everything runs locally on your device, so your code and data never leave your browser.
This project started as a simple comparison tool and has gradually evolved into a productivity-focused utility for developers, QA engineers, Salesforce professionals, and anyone who regularly works with structured text.
I'm actively improving DiffBoard and would love your feedback:
👉 What comparison workflows do you use most often?
👉 What feature would make DiffBoard an essential tool in your daily workflow?
Thank you for checking it out and supporting the launch! 🚀
