Keep Browser: Tree Tabs
Research, Compare, Share Tabs
Free · Designed for iPad. Not verified for macOS.
Keep Browser turns search results, comparison pages, and research links into organized tree-style tabs.
Open links at the top level, in the same group, or in a subgroup so research, shopping, travel planning, work, and study pages stay connected and easy to find.
Organized tab groups can be sent as shared links. Share tab groups across supported devices, making it easier to continue research across devices.
Useful when you want to:
• Open multiple search results and compare them later
• Organize products, hotels, restaurants, properties, or other candidates
• Keep frequently used pages and pages to read later in groups
• Manage many open tabs with hierarchy and labels
• Share a group of tabs with family, friends, or another device
Main features
• Tree-style tab management: Keep related pages in a clear hierarchy.
• Tab group sharing: Send selected tab groups as shared links and open them across supported devices. Private tabs are not shared.
• Keep Mode: Open tapped links as new tabs in a subgroup and preserve your research flow.
• Labels: Add names and colors to tab groups.
• Tab List, Tab Map, and related-node preview: Review open tabs and related groups, then jump to the page you need.
• Pinned tabs: Keep important pages from being closed by mistake.
• Closed tab restore: Restore closed tabs from the list.
• Ad blocking: Choose the blocking strength and adjust settings per site to balance cleaner pages with site compatibility.
• Private Mode: Browse without saving history or cookies.
• Fast scroll: Move quickly through long pages and large tab lists by dragging the scroll bar.
• Backup and restore: Back up and restore regular tabs, bookmarks, browsing history, search history, and settings across supported devices. Private tabs, cookies, and login state are not restored.
• Bookmarks, history, downloads, page translation, find in page, PDF search, desktop site display, and zoom are also supported.
Keep Browser is built not only to open pages, but to organize and preserve them. Manage research, comparison, saving, sharing, and backup in one place.
