Nyx

The browser that gives your computer its memory back.

Free. Version 2.0.9 for Windows 10 and 11, 100 MB.

Forty open tabs shouldn’t slow down your game. With Nyx, they don’t.

Made for Windows.
Calm by design.

Real Windows tabs and window buttons, the system’s own type, and nothing on screen that doesn’t need to be there.

Forty tabs.
A fraction of the memory.

Tabs you haven’t looked at in a while go to sleep and hand their memory back. Click one and it picks up right where you left it. Tabs playing music stay awake.

7.9 GB
Memory in use

Illustration. Real memory use depends on the sites you open.

Limits you set.

Cap how much memory, processor and bandwidth Nyx may use. Turn them on before a match and your game gets the machine, not your open tabs.

Ads and trackers, blocked.

Built in, using the same community filter lists as uBlock Origin. Pages load faster and fewer companies follow you from site to site. Allow ads on a site you want to support with one click.

Video that floats.

Pop any video out into its own window and drag it anywhere on your screen, on top of whatever you’re doing. Pause what’s playing from the taskbar or the tray.

And everything else you’d expect from a browser.

Download for Windows
  1. Open Nyx-Setup.exe from your Downloads folder.
  2. If Windows shows “Windows protected your PC”, choose More info, then Run anyway. It appears because Nyx is new, not because something is wrong.
  3. That’s it. Nyx keeps itself up to date from now on.
