YabArdia vs Edge
Ardia is a free, open-source Chromium browser for the Mac that pairs Arc’s sidebar with Dia’s look: pinned tabs, profiles you swipe between, Split View, the Chrome Web Store and uBlock Origin built in.
Edge is Microsoft’s Chromium browser on every desktop and phone, with Copilot built in. Since Copilot Mode was retired in May 2026, its agent, Browse with Copilot, comes with Microsoft 365 Premium in the US.
The short answer
- if you want Arc’s sidebar on Chromium, free and open source
- if you want Chrome extensions and uBlock Origin built in
- if you don’t want AI in your browser
- if you use Microsoft 365 and want Copilot in the browser
- if you want tabs down the side, workspaces, split screen and sleeping tabs built in
- if you work on Windows with Edge set up by your company
- if you miss Arc and want spaces, pins and folders kept, on a Mac
- if you already pay for Claude or ChatGPT and want it to work in your signed-in tabs
- if you want Claude Code, Codex or Cursor to drive a real browser over MCP

Where they differ
What separates them, area by area. Where one plainly has more, it says who; where it comes down to taste, it says so.
AIEdge leads
Only Edge has an agent that clicks, types and finishes tasks in your pages. Ardia has no AI of its own. Copilot reads the page, your tabs and history and sums up videos and PDFs; Browse with Copilot scrolls and types in pages for you, signed in, on Microsoft 365 Premium in the US.
Agents like Claude Code and CodexEdge leads
Ardia has no MCP server or command line for outside agents. Edge can be driven over MCP and a command line, through Microsoft’s Playwright MCP, which can launch Edge or attach to your running Edge.
Tabs and windowsArdia leads
Ardia has tabs down the side, spaces, Split View, folders in the sidebar and tabs that sleep. Edge has tabs down the side as a setting, spaces, Split View, folders in the sidebar and tabs that sleep.
PriceEdge leads
Ardia: Free and open source. Edge: Free, with Copilot; Browse with Copilot needs Microsoft 365 Premium $19.99/month (US).
Where it runsEdge leads
Ardia runs on Mac. Edge runs on Mac, Windows, Linux, iPhone and Android. On a Mac, Ardia needs macOS 14 or later and Edge needs macOS 13 or later. Ardia has no phone app: Mac only. On the phone, Edge: iPhone, iPad and Android; syncs tabs, favorites, passwords and history.
Engine and extensionsa matter of taste
Both are built on Chromium, as Chrome is, so sites work as they do in Chrome. Both take extensions from the Chrome Web Store.
PrivacyArdia leads
Ardia has an ad blocker built in and open code. Ardia syncs end to end encrypted through a folder in your own iCloud Drive, with no server of its maker in between; crash reports are opt-in. Edge has a VPN. Copilot may use your question, the page, your open tabs and history; Browse with Copilot keeps screenshots up to 30 days, not for training, Microsoft says.
