Luma vs Arc
Arc made tabs in a sidebar and separate spaces feel natural. In 2025 its makers stopped adding features to it to work on Dia, their new browser. Luma keeps that way of working, with tabs in a sidebar, workspaces, split view and a command palette, in a browser that is updated often and blocks trackers and ads from the first page.
What stays the same
- Tabs in a sidebar, grouped into workspaces with their own name, colour and symbol, and Essentials at the top.
- Split view with up to four pages, link previews, and a command palette (Ctrl K) for tabs, history and commands.
- Chromium underneath, like Arc: sites behave the same and extensions come from the Chrome Web Store.
What changes
- Trackers, ads, third-party cookies and cookie banners are blocked from the first page.
- No account and no sign-in. Sync, if you want it, goes to a folder or WebDAV server of yours, encrypted end to end.
- Tabs can also sit on top, and compact mode hides the sidebar until you reach for it.
Moving over
On first launch Luma imports from Arc directly: your spaces and their pinned tabs become bookmark folders, and your history and open tabs come along. Saved passwords come over where Arc allows it, otherwise as a CSV file.
