A Chrome alternative that still runs your extensions.

Acira runs on Chromium, the engine behind Chrome and Edge, so websites work the same and extensions install from the Chrome Web Store. It blocks ads from the start, needs no account, and your bookmarks and history come with you.

Measured on one Windows 11 PC before this release, with a fresh Chrome profile and no extensions. Chrome loads the ads Acira blocks, which is most of the gap.

Your extensions

Extensions install from the Chrome Web Store with an Add to Acira button. Of 26 popular extensions we tested, 20 work, 4 work with limits and 2 don't yet. Working ones include uBlock Origin Lite, Bitwarden, 1Password, Proton Pass, Dark Reader and Vimium.

What Acira adds

  • Private and Tor tabs next to your normal tabs.
  • Rewind keeps the tabs and windows you close for up to a week.
  • Workspaces, up to eight per profile, and ones you can lock (beta).
  • Built-in blocking of ads and trackers, on from the start.

What Chrome has that Acira doesn't

There's no cloud sync and no mobile app, and protected streaming such as Netflix isn't supported on Windows yet. See the known limits.
