Seedtrunk: Tab Saver & Session Manager

Seedtrunk is a tab saver and session manager: save tabs from one window or all windows as a named session and restore them in one click.

Seedtrunk is built around one promise: your saved tabs do not disappear. Every save shows its date and time, snapshots are taken on their own, and anything you delete waits in the trash for 30 days.

• Save tabs for later: this window, all windows, or save & close to free memory; name the session right away
• Restore a session, one window or one tab: in a new window, in this window, or in place of this window
• Big sessions restore lazily: 1000 tabs open without freezing, with progress and a Stop button
• Automatic snapshots every 5–60 minutes and one right before the browser closes, on a timeline; pinned snapshots are never cleaned up
• Undo after every delete, a 30-day trash, earlier versions of an updated session
• Search titles and addresses across all sessions and snapshots
• Find and remove duplicate tabs inside a session, across sessions or in an open window
• Import the text export of OneTab and Tab Session Manager JSON files; lines that are not links are listed, never silently dropped
• Export everything to JSON (imports back without loss), a web page with links, or a plain list
• Optional backup file in your Downloads folder every day or week, so a profile reset cannot wipe your sessions
• Tab groups keep their names and colours, pinned tabs stay pinned; private windows are left out unless you turn them on
• Keyboard shortcuts, light and dark theme, 16 languages, right-to-left layout for Arabic

Private by design: no account, no server, no analytics, no ads. Seedtrunk does not read the pages you visit; it sees only tab addresses and titles, and all data stays in your browser. Works offline in Firefox and Opera.

Diese Version ist kostenlos.
