A developer-friendly code comparison tool. 🔀 DiffBoard – Modern Code, JSON & Text Comparison Tool DiffBoard is a developer-focused Chrome extension that helps you quickly compare code, structured data, logs, and plain text using a clean, visual, and distraction-free interface. Whether you are reviewing code changes, validating API responses, comparing deployment files, analyzing server logs, or checking configuration updates, DiffBoard helps you instantly see exactly what changed — all processed entirely inside your browser. 🚀 Why Install DiffBoard? DiffBoard is built specifically for software development, debugging, and system administration workflows where you need to compare raw scripts, API payloads, templates, configuration variables, and server logs. DiffBoard focuses on speed, usability, privacy, and developer productivity—working completely offline with no websites to visit, no file uploads, and no distractions. ✨ Key Features 🔍 Side-by-Side & Unified Comparison Compare content using split side-by-side or unified line-by-line diff views. DiffBoard provides GitHub-style visual highlighting and full file rendering, making it easy to identify added (+), removed (-), and modified (~) lines. 📊 Smart Diff Summary See changes at a glance with live metrics for added, removed, and modified lines, visible immediately above the comparison container. 📋 Powerful Copy & Export Tools Quickly copy the original content, modified content, full rendered diff, unified patch format, or filter your selection to copy only added or removed lines. You can also export comparison results directly to local TXT or HTML files, with toast alerts confirming successful clipboard actions. 🧩 Format, Validate & Minify Built-in formatting tools help you clean and analyze structured content faster. You can format, minify, validate, or sort keys for programming code and JSON payloads during API testing, configuration reviews, and debugging. 📁 Drag & Drop File Comparison Compare files without manual copy-paste. Simply drag files from your computer and drop them directly into either editor panel to load web markup, structured configuration parameters, source code, data sheets, logs, and text files automatically. 🔎 Advanced Diff Workflow Designed for reviewing large changes efficiently. Features include live search inside rendered diffs, sequential next/previous match navigation, centered match scrolling, context toggles to restrict views to changed sections, and controls to ignore case, whitespace, or line-ending differences. 💾 Session Recovery Never lose your work accidentally. DiffBoard automatically restores previous editor contents, your active tab selection, and theme preferences so you can continue where you left off after a refresh or browser restart. ⌨️ Keyboard Shortcuts Built for developer productivity, DiffBoard supports hotkeys for comparing code, clearing editors, copying diffs, toggling workspace themes, applying format tools, and switching tabs. An in-app shortcuts guide is accessible directly from the toolbar. 🪄 Optimized for Large Files DiffBoard includes usability enhancements for larger comparisons, featuring loading indicators during heavy renders, debounced comparison execution, optional line wrapping, and responsive scrolling. 🌓 Light & Dark Themes Choose the interface that works best for your workspace with clean light and developer-friendly dark theme modes that persist across browser sessions. 🔐 Privacy & Security First DiffBoard is built with developer privacy at its core. It requires no user data collection, tracking, analytics, external API calls, or remote server requests. The extension works fully offline, ensuring your code and files never leave your device. 🛠 Built for Developers DiffBoard is a reliable, local utility for software engineers, web developers, system administrators, QA testers, and technical analysts who regularly review code differences and structured data formats. 🚀 Built for Continuous Improvement DiffBoard continues to evolve with plans for VS Code–style compare view interfaces, merge and change acceptance controls, local comparison history, recent session management, and advanced review workflows. 💡 Simple. Fast. Visual. If you frequently compare code, JSON, logs, or text and want a reliable, privacy-first, offline tool, DiffBoard is built for you. Install DiffBoard and make code comparison effortless.
