The Sidebar
Persistent pinned tabs, folders, and favorites. The sidebar is your workspace, not a tab list that disappears.
Arc Browser entered maintenance mode on May 27, 2025. The Browser Company was acquired by Atlassian in October 2025 for roughly $610M. No new Arc features have shipped since. Sources →
The four features Arc users built workflows around — and the six famous extras.
Persistent pinned tabs, folders, and favorites. The sidebar is your workspace, not a tab list that disappears.
Separate contexts — Work, Personal, a specific project — each with its own pinned tabs and color.
One keystroke to search bookmarks, tabs, history, and actions — Arc's power-user shortcut.
Rules that auto-route links: "anything from notion.so opens in my Work Space."
Zen, Brave, Vivaldi
For: people ready to relearn workflows, comfortable with Firefox or a new engine.
Trade-off: 1–3 hours of manual rebuild, lose Chrome extensions, lose Chromium-only sites.
SupaSidebar
For: macOS-only users who want a sidebar that floats across every browser.
Trade-off: Mac-only, paid for full features, a separate app to install and launch.
Chrome · Edge · Brave · Vivaldi
For: people who live in Chrome / Edge / Brave and want zero friction.
Trade-off: Chromium browsers only — no Safari, no Firefox.
Pin tabs, group them in folders, keep favorites visible across every window — the same persistent workflow Arc made famous.

Switch between Work, Personal, and project Spaces with one keystroke. Each Space has its own pins, folders, and theme color.

Leap auto-groups your tabs by topic — research, social, work, shopping — so 50 tabs feel like 5.

Cmd+Shift+L opens Leap. Arrow keys and number keys jump between Spaces. The search bar covers tabs, bookmarks, and history at once.
