ContextOS

Save, search and restore your open tabs as sessions. Local-only, no tracking.

Too many tabs? ContextOS saves everything you have open as a named session, so you can close it all and pick up exactly where you left off. What it does Save all open tabs as a named session with one click Restore any session in a new window Search across session names, page titles and links Automatic snapshots every 30 minutes, so a crash or an accidental window close doesn't cost you your work See exactly which tabs are inside a session before you restore it Private by design Everything is stored locally in your browser. Nothing is uploaded. No account, no sign-up, no servers No analytics, no tracking, no ads Only four permissions, each explained below Why these permissions? Tabs: to read the title and link of your open tabs so they can be saved, and to open them again when you restore Storage: to keep your sessions on your device Alarms: to run the automatic snapshot timer Unlimited storage: so large sessions are never cut off Good to know Automatic snapshots keep the 20 most recent. Sessions you save yourself are never deleted automatically. Pages like chrome:// settings and the new tab page can't be saved, because Chrome doesn't allow extensions to reopen them. Coming next: tab suspension to cut memory use, keyboard shortcuts, and workspaces. Questions or feedback? Contact: tkdevelopers.app@gmail.com.
