SessionNest – Session Manager & Tab Group Saver

Session manager that never loses your tabs: auto-save, crash recovery, tab groups kept, 100+ tabs without freezing. 100% local.

Never lose your tabs again — and reopen 200 of them without freezing your computer. SessionNest is a session manager and tab saver that saves your windows, tabs and tab groups with one click, auto-saves everything in the background, and brings it all back after a crash or restart. It's built for people who keep dozens or hundreds of tabs open. Lost your tabs after an update, a restart or a crash in another tab manager? SessionNest keeps a history of automatic snapshots, so one bad moment can't wipe your work. Switching takes one click: paste your OneTab list or import a Session Buddy or Tab Session Manager export file. ★ WHAT MAKES IT DIFFERENT • Tab groups are kept — names, colours, collapsed state and pinned tabs come back exactly as they were. • Fast open: only the tab you're looking at loads; the rest wait until you click them. 120 tabs open in seconds, with almost no memory use. • Crash & restart recovery: if the browser closes unexpectedly, SessionNest offers to bring back your last session. • Auto-save every few minutes and 30 seconds after any change — no button to remember. • Your data never leaves your computer. No account, no sign-up, no tracking. ★ FEATURES • Save the current window or all windows (Alt+Shift+S) • Open a whole session, one window, one tab, or just the tabs you select • Open a session in a new window or in the current one • Search every saved tab by title or address • Rename, delete (30-day trash), remove duplicate tabs • Copy a session as text, export to JSON • Import from OneTab, Session Buddy, Tab Session Manager or a plain list of URLs • Light and dark theme ★ SESSIONNEST PRO (14-day free trial, no card needed) • 30 days of auto-save history (free keeps the last 5) • Automatic daily backup file on your computer • Merge sessions and move tabs between sessions Pro is $4.99/month or $29 once. ★ PRIVACY Everything is stored locally in the extension's own storage.
