Ardia 0.2.46 keeps tab switching quick with 200 tabs open

Ardia, the free open-source Mac browser with Arc's sidebar and Dia-style polish, released version 0.2.46. Switching tabs and opening a new one no longer slow down as tabs pile up, and with 200 tabs open a switch does about a third of the bookkeeping it did before.

Onboarding drops from eight steps to three. A tab switches when the mouse button goes down, links to other sites open in a Peek by default as in Arc, and clicking the address edits it in place. With Auto Picture in Picture on, a playing video pops out when Ardia's window goes out of sight. The release also lists 31 fixes, including one that stops Sync from uploading your whole profile again every 10 minutes.

Ardia is built on Chromium by Mantra Patel, and its first public build shipped on September 25, 2026. You can move the address bar into the sidebar, split a window into up to three panes, and keep a video floating in the corner when you switch tabs. Chrome Web Store extensions install as they do in Chrome. The full uBlock Origin is built in for ads, trackers and cookie banners, and Google's background services are compiled out.

Profiles keep their own logins, history and extensions, and Sync is end-to-end encrypted through a folder in your own iCloud Drive. The importer brings bookmarks, history and passwords from Chrome, Safari, Firefox, Arc, Dia and others, plus Arc's spaces, pinned tabs and themes. There's a ⌘L command bar, a shortcut that sweeps away tabs you haven't touched, and background tabs freeze on their own.

A command-line tool lets your own Claude Code or Codex drive the browser with ardia browse, logins included, and your Mac's other apps with ardia computer. In 0.2.46, ardia browse answers an action with the text of whatever it opened, so an agent needs fewer steps.

Ardia is free under GPL-3.0, with its own code under Apache-2.0. It runs only on Apple Silicon Macs with macOS 14 or later. Passkeys work with Touch ID but not iCloud Keychain, and DRM streaming sites open in WebKit. Install it from the DMG or with brew install ardia-browser/tap/ardia.
