nimbus

A Chromium browser for Windows 11 with almost no browser in it. No address bar, no menu bar, no toolbars — a floating rail, a strip of tabs, and the page you came to read, through real translucency.

What it does

Everything a browser needs.
Nothing it doesn't.

Each of these exists because the alternative was worse, not because a feature list needed filling.

Real translucency

The Windows 11 acrylic material, sampling your actual desktop — including whatever app is sitting behind the window. It survives filling the screen, which took some doing.

Profiles that actually separate

Each profile is its own Chromium session: separate cookies, storage, cache and logins. Sign into the same site twice, in two profiles, at once.

Locked profiles

Give a profile a passcode and it asks before opening. Stored as a salted scrypt hash — the passcode itself is never written down.

Passwords, encrypted by Windows

Saved logins are sealed with DPAPI against your Windows account. Nothing is ever written in plaintext — if Windows won't encrypt, Nimbus refuses to save.

The command palette is the interface

⌘K or Ctrl+K opens everything: navigate, switch tabs, jump to a shortcut, reopen something you closed, inject your own CSS. The address bar was removed because this replaced it — click the tab you are already on to edit its URL in place.

Sessions that come back

Every profile remembers its own tabs. Switch profile and the tabs switch with it; reopen Nimbus and you are where you left off.

Profiles

One browser, several people — or several of you.

Pick one and watch what moves. Nothing crosses between them.
