Kepsul – Tab & Session Manager

Tab & session manager: never lose a tab. Automatic session history, collections and one-click park.

Kepsul remembers your tabs so you never have to. ⏱ AUTOMATIC HISTORY A few seconds after anything changes, Kepsul quietly saves your open windows. Chrome crashed? Closed the wrong window? An update wiped your session? Open History and go back to any moment of the last 30 days. Choose how often it saves, and compare any snapshot with the previous one or with what is open right now. ⌨ FIND ANY TAB WITH ALT+S Press Alt+S on any page: a search bar drops in, you type a few letters, and Enter takes you to that tab, even in another window. Closed tabs Kepsul has saved show up too and reopen with Enter. 🅿 PARK IN ONE CLICK Alt+W (or the popup button) closes every tab of the current window into a parked collection and frees your memory. Undo for a minute, restore any time. Rules file tabs from chosen sites straight into a collection you name, and an optional idle rule parks tabs you have not touched for hours. 📁 COLLECTIONS Save a snapshot, a window or a selection of tabs under a name. Tab groups keep their names and colors. Add tags and notes, star the ones you use most, and drag tabs between collections. ♻ RESTORE THE WAY YOU WANT Everything, one window, or just the tabs you tick; into a new window or the current one. Restored tabs load only when you click them, so opening 50 tabs does not freeze your machine. 🧹 DUPLICATES See every page open more than once across your windows and close the extra copies with one click. 📤 EXPORT Copy a snapshot or collection as Markdown or plain text, or download it as a tidy HTML page. 💾 DAILY LOCAL BACKUP Kepsul writes a JSON backup to your download folder every day, and never upgrades its database without writing one first. Your data outlives the extension. The Backups screen lists every backup; the newest ones restore with one click, and a full restore always writes a safety backup before replacing anything. 📥 IMPORT Coming from OneTab, Session Buddy, Toby or Tab Session Manager? Import your export file in one click; browser bookmark files work too. Importing never overwrites anything you already have. 🔎 SEARCH Find any tab you have ever saved by title, address, collection name or tag. 🔒 PRIVACY BY DESIGN Everything stays on your device. Kepsul makes zero network requests: no analytics, no servers, not even favicon downloads. Only two permission warnings at install. ✅ FREE FOREVER Everything local is free and stays free. If a paid tier ever exists, it will only cover new optional features like encrypted sync between devices.
