An alternative to Arc on Windows

If you liked Arc’s sidebar and spaces but want a browser that keeps moving forward, Luma works in a very similar way, and adds strong privacy on top.

What carries over from Arc

Tabs live in a sidebar, grouped into workspaces with their own name, colour and symbol. The sites you open every day go in Essentials at the top and stay there in every workspace.

Split view, a command palette (Ctrl K), link previews that open over the page, and a compact mode that hides the sidebar until you reach for it: the habits you built in Arc keep working.

What Luma adds

Trackers, ads, third-party cookies and cookie banners are blocked from the first page. There is no account and no sign-in, and sync, if you want it, goes to a folder or WebDAV server of yours, encrypted end to end.

Tabs can also sit on top if you prefer, music playing in another tab can be controlled from the sidebar, and reader view can read articles aloud.

Moving over

On first launch Luma imports from Arc directly: your spaces and their pinned tabs become bookmark folders, along with your history and open tabs, and saved passwords where Arc allows it (otherwise as a CSV file). Extensions install from the Chrome Web Store, as in Arc.
