👋 Hey Product Hunt!
Browser SplitView Master was born from a simple frustration: constantly juggling multiple browser windows just to compare pages, monitor dashboards, review content, or test websites side-by-side.
As developers, this problem showed up everywhere. We found ourselves switching between API documentation, Swagger responses, staging and production environments, frontend implementations, admin dashboards, logs, analytics tools, and design references dozens of times a day. The constant tab and window hopping broke focus and slowed down workflows.
What makes Browser SplitView Master different is its synchronized scrolling capability. Multiple panels can scroll together in real time, making it incredibly easy to compare API documentation, translated content, staging vs production pages, design implementations, long-form documents, and website versions without constantly adjusting each panel manually.
Instead of opening countless tabs and windows, we built a way to transform a single browser tab into a customizable multi-panel workspace. You can create up to 16 resizable panels, synchronize scrolling across pages, save layouts, and instantly switch between common grid templates.
Some of our favorite use cases include:
• Comparing staging vs production websites
• Matching frontend implementations with designs
• Validating API responses across multiple environments
• Comparing API documentation and implementation side-by-side
• Monitoring logs, analytics, and dashboards simultaneously
• Comparing documentation versions with synchronized scrolling
• Cross-referencing translations and content updates in perfect alignment
• Comparing products, specifications, and reviews while researching online
Everything works locally inside your browser. No accounts, no servers, no analytics, and no data collection.
