Leap

Leap brings the sidebar and spaces idea from the Arc browser into Chrome. It lives in Chrome's side panel and keeps tabs you save in place even after you close them in the normal tab bar, so one click reopens them. Each space groups tabs, folders and pinned sites for a context such as work, a side project or personal browsing, and switching between spaces takes a single click.

Folders can be nested three levels deep, tabs can be dragged between spaces, and a right-click menu offers copying links, renaming, duplicating and muting. Each space can have its own theme with light or dark mode and accent colors. Spaces, saved tabs, folders, pins and settings sync through the vendor's server, with sign-in by email for other Chromium browsers.

Leap runs in Chrome and in Chromium-based browsers including Edge, Brave and Vivaldi, but not in Firefox or Safari. The vendor is open about limits: as an extension it cannot hide Chrome's horizontal tab bar, and its spaces are built on tab groups, so they share one set of logins. It is free for everyone with no sign-up needed to start.
