Tab Harbor

Arc-style sidebar tab manager: pinned tabs and Spaces for Edge / Chrome

Tab Harbor brings Arc's signature sidebar experience — pinned tabs and Spaces — to Microsoft Edge and Google Chrome. For you if: • You drown in open tabs and can't find the one you need • You want to swap entire tab sets between work, research and personal contexts • You migrated from Arc and miss that sidebar ■ Pins — your go-to sites, app-like Pinned sites live at the top of the sidebar. Clicking one focuses its tab (or opens it), and that tab merges into the pin instead of cluttering your tab list. The pin follows in-page navigation, and "–" closes the tab while keeping the pin. Organize pins into nested, collapsible folders with drag & drop, and rename pins or edit their URLs. ■ Global Pins — one click from any Space Keep your daily sites in a compact icon grid shared across all Spaces (like Arc's Favorites). Just drag a tab or pin onto it. ■ Spaces — switch whole working contexts Keep separate sets of pins and tabs for work, research, personal life. Switching a Space expands its tab group and collapses the rest, with theme colors per Space. New tabs join the active Space automatically, and your layout survives browser restarts — tabs are restored lazily to keep memory usage low. ■ Import from Arc Pick your Arc StorableSidebar.json and bring over Spaces, pinned tabs (with folder structure), Favorites and open tabs. ■ Keyboard shortcuts Alt+Shift+H: toggle the sidebar / Alt+Shift+. and Alt+Shift+,: cycle Spaces ■ Privacy Everything is stored inside your browser. No servers, no analytics, no tracking.

Pairs nicely with Edge's vertical tabs for the full Arc-like layout.
