Comet Workspaces

Save and restore browser workspaces with tabs, pinned state, and tab groups. Edge Workspaces-style for Comet.

Comet Workspaces is a power-user workspace manager for the Comet browser. Save the exact state of a browser window — every tab, every pinned tab, every tab group — and restore it on demand. Built for people who juggle multiple client contexts, projects, or research threads in parallel. What's new in v1.14.0 Favicons are now cached locally when a workspace is captured, with a generated letter-tile fallback when a favicon cannot be fetched. The previous build rendered favicons through Chrome's built-in service, which routed every workspace URL through Google's favicon endpoint when the popup opened. v1.14.0 keeps your workspace URLs entirely local. Key features Save any browser window as a named workspace, including pinned tabs and tab groups. Live-link a workspace to its window so subsequent edits sync automatically (window close, restart, tab adds and removes — all captured). Restore any workspace into a new window with one click, with a confirmation dialog so accidental clicks do not blow away your current session. Tag workspaces (up to eight tags, lowercase, de-duplicated) and filter the list with #tag search. Drag to reorder workspaces manually — useful when live-linked workspaces would otherwise float to the top of an updated-at sort. Inline rename by double-clicking a workspace name. Keyboard shortcuts (Alt+Shift+W to open the popup, Alt+Shift+S to save, Alt+Shift+O to open) keep your hands on the keyboard. Restore in suspended mode to bring back a large workspace without immediately loading every tab. Storage is local. Workspaces persist across browser restarts via chrome.storage.local, with an auto-sharded index that scales to several hundred workspaces without hitting Chrome's per-key storage limits. Keyboard shortcuts Alt+Shift+W — open the popup Alt+Shift+S — save current window as a workspace (or update the linked workspace) Alt+Shift+O — open the most recent workspace Privacy Comet Workspaces does not send your tabs, URLs, titles, or any workspace data to any external server. All data is stored in chrome.storage.local on your device. The extension does not include analytics, telemetry, or remote configuration. From v1.14.0 onwards, favicon rendering is also fully local. Compatibility Built as a Manifest V3 extension for the Comet browser (a Chromium fork). Works in Chrome and other Chromium-based browsers that support the same APIs.
