Groups and workspaces
Name a group, give it a color, fold it to a dot. Put a whole group away as a workspace and bring it back later.
The web, all the way around.

01
Tabs on a ribbon
Groups of tabs run along the top of the window, bend round the corner and carry on down the side, every title turning with the curve. The page gets the middle, all of it.
02
Quiet by default
Trackers are blocked, tracking tags are cut from links and cookie banners are refused before you see them. Nothing to switch on, and the list of what was stopped is there to read.
03
Yours alone
No account. No telemetry. No AI unless you unlock it yourself. What you browse stays on your Mac, and sync, if you want it, goes through a folder you choose, sealed with your passphrase.
What is in it
02
Split view and peek
Two or more pages side by side. Option-click a link to look at it without leaving where you are.
03
Vertical tabs, if you prefer
The same groups as a list down the left, titles reading straight across. One setting.
04
Tabs that sleep
Only the tabs you are using stay awake. The rest keep their place and wake where you left them.
05
Profiles with their own cookies
A group can sign in separately and choose its own search and protections. Work stays out of home.
06
Real extensions
Run by WebKit, as in Safari. You see what one asks for before it is added. uBlock Origin Lite works today.
07
A command bar for everything
⌘K to search, jump to a tab, do sums or run a command. Every shortcut can be changed.
08
Bring your browser with you
Bookmarks and history from Chrome, Firefox, Safari, Brave and Zen, and Arc's spaces as groups.
09
An engine of its own
An experimental reader engine, written from scratch, that runs no scripts and shows every request it makes.
Make it yours
The frame around the page takes any color you like, or a picture. The ribbon and the address deck change their ink to stay readable. Try one; this page will wear it too.
Frame: Night
Privacy
Every request Nfiniti itself makes is written down in one table, with what is sent and to whom. Left alone it makes one: asking GitHub whether there is a newer build, which you can switch off. Everything else is the pages you open.
It is honest about its limits too: sites behave as they do in Safari, because WebKit draws them, and what the blocker cannot see is said plainly instead of promised.

On a MacOpen the disk image and drag Nfiniti onto Applications, or open it there and it installs itself. The alpha is not notarized by Apple yet, so the first time, right-click the app and choose Open.
UpdatesNfiniti looks for a newer release on GitHub and tells you when there is one. You can switch that off, and nothing about you is sent.
On WindowsRun the installer. It installs for you alone, needs no administrator, and adds Nfiniti to the Start menu. Windows may ask whether to run it, since the alpha is not signed yet.
