Uranus Browser for iPhone In development

A little less chrome.
A lot more web.

The same idea of a calmer browser, built for your thumb. Native on iPhone, with floating controls that give the page room to breathe. Fits in your hand; have fun all day.

  • Tabs, in Spaces. Colour, context and tab cards for the different parts of your day.
  • Algorithm Diet. Explore your browsing topics with on-device analysis.
  • Your own corner of the web. Private browsing, site blocking and a look you can make your own.

Desktop agent control and meeting features aren’t available on iPhone yet.

Algorithm Diet · macOS + iPhone

You are what you browse.
Give your curiosity a little more room.

Look beyond screen time. See what you read, watch and learn, with a nutrition label for your corner of the internet. Keep the people. Lose the rabbit holes. Your feed called; it thinks you need more fiber.

Learning and building took the largest share of this sample week. Long reads made a little room for deeper thinking, too.

On-device analysis. Your browsing stays yours.

A little help, in the room

Be in the conversation.
We’ll keep the thread.

Invite your assistant when you want another pair of ears. Record when you’re ready. Leave with the decisions, not a page of half-finished notes.

A replay of a run, slowed down: running the search waited for an Allow. Google Flights is shown as an example site. Uranus Browser isn’t affiliated with Google, and the fares and Uranus itinerary are made up.

Everything Arc taught us, rebuilt

A smooth ride,
from first click to last.

    Command bar

    ⌘T searches open tabs, the archive and history. gh, npm, mdn and caniuse shortcuts; paste a JWT or a timestamp to decode it. Find the Tab Chad you’ve been chasing all day.

    Spaces

    A colour and an emoji per context, with separate cookies when you need to be two people. ⌃1–⌃9. Keep work and play in separate Spaces. Some tabs like a little privacy.

    Open

    Peek

    Links from pinned tabs float in a preview. Esc closes it, Open keeps it. A quick peek before you commit.

    Split View

    Two pages side by side. ⌃⇧= to split, ⌃⇧- to leave. A very productive arrangement.

    Dana Let's ship the sidebar fix Friday.

    Meeting recorder & assistant

    Password manager

    Save and fill logins with Chromium’s built-in manager. Import saved Arc passwords with macOS Keychain authorization. Good protection never goes out of style. Invite-only, front door to back.

    A new browser. Your familiar setup.

    Bring your Arc Plug and Harnesses.

    Leaving Arc? Bring your setup and your favourite plug-ins. Import during onboarding or later in Settings. Spaces, nested folders, favourites, pinned tabs and open tabs land in their places. History and saved passwords come too.

    • Your structure, preserved. Space names and colours, folders and pinned sites map into the new sidebar.
    • Move at your pace. Import again without duplicating your tabs or replacing existing logins.

    Made for people who build the web

    Your dev servers
    live in the sidebar.

    • Running locally. Anything listening on this Mac shows up, named after its project folder.
    • Environments. ⌥⌘E jumps the same path between local, staging and prod.
    • Console badge. Local tabs count their errors; one click opens the Console.
    • Boosts. Per-site CSS and TypeScript, edited in the browser, applied live. Smoother scrolling. Softer landings.
    • MCP for coding agents. Codex, Claude Code, Cursor and other agents read tabs, logs and screenshots, then navigate, click and type through a local, token-gated server.

    Not Electron. Not a wrapper.

    A real Chromium fork,
    top to bottom.

    Google sign-in works, extensions install from the Chrome Web Store, and DevTools is DevTools. On top sits a shell written from scratch, and a small native helper that keeps your AI and your data on your Mac.

    FAQ

    Questions,
    answered.

    Is it really free?

    Yes. The browser is free. The AI features use your own ChatGPT plan, an OpenAI API key, or a model running on your Mac.

    Can I bring my Arc or Chrome setup?

    Yes. During onboarding or in Settings › Import, bring Arc Spaces, colours, nested folders, favourites, pinned and open tabs, history and saved passwords. Arc password import needs macOS Keychain authorization. Chrome import is available too.

    Do Chrome extensions work?

    On macOS, yes: extensions install straight from the Chrome Web Store. iPhone extension support is planned.

    What can the agent do without asking?

    Read, scroll, click, type into ordinary fields, navigate and switch tabs. Submitting, sending, buying, signing in, account changes, uploads, downloads and secrets all wait for your approval.

    Which Macs are supported?

    Apple silicon Macs. The app keeps itself up to date.

    Is there an iPhone version?

    A native iPhone version is in development, with Spaces, tab cards, private browsing and on-device Algorithm Diet. The images above are from the app. Desktop agent control and meeting features aren’t available on iPhone yet.

    Can I walk through onboarding again?

    Yes. Open Settings › General › Replay onboarding. It keeps your existing tabs, Spaces, passwords and other profile data.

    Is there a Windows version?

    Not yet. macOS first.
