One Panel is an all-in-one Manifest V3 Chrome extension built around a modern side panel interface. Instead of installing separate extensions for JSON formatting, clipboard history, screenshots, QA helpers, URL tools, and more, you get one searchable home for developer tools, QA utilities, web productivity, design helpers, and optional privacy features—all in one place. HOW TO USE IT Install One Panel from the Chrome Web Store. Click the toolbar icon to open the side panel. Search for any tool or open the command palette with Ctrl/Cmd+Shift+Space. Pin favorites and browse by category when you want to explore. Use right-click context menus to send selected text, links, or images straight into the right tool.
