SessionKeep - Tab & Session Manager

Your tabs, safe. SessionKeep takes a snapshot of your open windows every few minutes and again when you close a window, so a crash, a restart or a stray click never costs you a research session.

Save and restore • Save this window or all windows in one click, or save and close to clear the clutter • Restore everything, one window or a single tab, in a new window or this one, or swap it with what's open now • Pinned tabs, tab groups with their names and colours, and window sizes come back as they were • Large sessions open without loading every tab at once • Keyboard shortcuts to save a window, save everything or open the manager, and an optional tab count on the toolbar icon

Organise • Give a session one of 8 colours and filter the list by colour • Copy sessions into your browser bookmarks, or turn a bookmark folder into a session

Find anything • Search every saved tab, every snapshot and the tabs open right now • "Open now" view to jump to a tab, close it, or close duplicates

Never lose them • Snapshots only when something changed, kept on a schedule you set (default: everything for 6 hours, hourly for 3 days, daily for 60 days) • Pin a snapshot to keep it forever • Optional backup file to your Downloads folder every few days • Full backup and restore in one file

Move in and out • Import from OneTab, from JSON exports of other session managers, or paste a list of links • Open bookmarks files from Chrome, Edge, Firefox or Safari • Export to 15 formats: Markdown list or table, web page, bookmarks file for any browser, CSV, TSV, JSON, plain text, address list, OneTab, OPML, XBEL, Org mode, BBCode and wiki text • Copy a session as clickable links that paste cleanly into email, documents and chat

Private by design: no account, no cloud, no tracking. Incognito windows are never saved.
