A browser for macOS, written in Swift on the WebKit your Mac already has. Tabs down the side, Spaces, split view, peek.
A set of tabs for each part of your day, each with its colour, and its own logins if you want them.
Two tabs side by side, each in its own card, in one window.
A link opens in a card over the page. Close it, keep it as a tab, or open it beside the page.
No extensions to hunt for. These come with Eimyr, and run on the macOS you already have.
Brave's adblock-rust engine with uBlock Origin's scriptlets, built into the browser. Nothing to install.
Any part of a page in a window of its own, still live.
A site in your own font and colours, with your CSS and JavaScript.
A page of your own, as a tab, edited like Notion.
Claude Code, Codex and scripts drive Eimyr through eimyr and its MCP server, in a Space of their own with its own profile.
Add to Dock gives a site its own app, icon and window.
Filled after Touch ID, only on the site they belong to. Bitwarden built in.
Merge requests waiting for your review on GitLab, pull requests and issues on GitHub, or a feed's newest posts, as pinned tabs that keep themselves up to date.
Addresses, searches, history, open tabs in every Space and every command, from one place.
Whole pages in your language, with Apple's on-device translation. Nothing goes to the cloud.
Pick a part of a page and get a notification when it changes the way you asked: anything, a number going below a value, some text showing up.
Spaces, pinned tabs, folders and notes through iCloud Drive or any synced folder. No account.
Extensions made for Chrome or Safari, added straight from the Chrome Web Store.
Tabs you haven't looked at for an hour unload, and wake when you come back to them.
Arc is winding down. Eimyr reads its sidebar on your Mac and sets it up again here, Spaces and all, in under a minute.
Also from Chrome, Brave, Edge, Vivaldi, Dia, Safari and Firefox: bookmarks and history. Settings › Eimyr › Import.
Not yet: Eimyr is in public beta. It's a browser used every day, but expect rough edges. It checks for new versions by itself and installs them when you say so. If something breaks, write in.
Yes. Eimyr is free to download and use on any Mac of yours, for anything personal or work. No account, no subscription, no ads.
WebKit comes with macOS and is what Safari runs on, so Eimyr doesn't carry a second engine of its own. That makes it lighter on memory, all the more as tabs you haven't looked at for a while sleep. It's the engine Apple tunes for the Mac's battery, and it gets Apple's security fixes with every macOS update, and Eimyr itself is written natively in Swift and AppKit.
Sites that work in Safari work in Eimyr. A few sites only let Chrome in; Eimyr presents itself to those as Chrome, so they open as they should.
Protected video plays where the site supports WebKit's FairPlay, as it does for Safari. Sites that only use Chrome's Widevine won't play it.
No. Eimyr needs a Mac with Apple Silicon and macOS 15.4 or later.
On your Mac. Eimyr has no servers and no accounts, and sends nothing about what you do. Passwords go into your macOS Keychain. Everything it fetches by itself is listed on the privacy page.
Yes, if you let them. Claude Code, Codex and scripts drive Eimyr through its eimyr command and MCP server, in a Space of their own. How agents use Eimyr.
Write to [email protected]. Eimyr is made by one person.
