Runs on your Mac
Blocking happens on your device, not through an external proxy or VPN provider. Your traffic stays yours.
For Mac
Block adult websites on Mac.
Nohub helps you block adult websites on Mac, keep protection active in the background, and track your progress over time.
No accounts No tracking No external VPN service
Nohub does not depend on an external VPN service. Protection runs on your Mac itself — quietly, in the background, across browsers where technically true.
Cross-browser protection
Where technically true, blocking applies across the browsers you use on Mac — not only one.
Background protection
Once activated, Nohub keeps working when the app is closed. Open it when you want to check progress.
Timer and levels
See the time since you chose to stop, your current level, and the next milestone — calm and uncluttered.
Quiet, focused interface
A compact main window centered on your timer, with the controls that matter and nothing else.
Private by design
No accounts, no tracking. Everything stays on your Mac.

Mac blocking, answered.
How do I block porn sites on Mac without a VPN?
Install Nohub from the Mac App Store, complete the short setup, and activate the shield. Blocking runs on your Mac itself — your traffic is not routed through an external VPN service or proxy.
Does it block adult websites in Chrome and other browsers?
Yes, where technically supported. Nohub blocks at the device level rather than inside one browser, so protection applies across the browsers you use on your Mac.
Does blocking stay active when the app is closed?
Yes. Once activated, Nohub keeps working quietly in the background. The app itself is mostly where you check your timer, level, and next milestone.
Can other people see my progress?
No. There are no accounts and no tracking. Your timer, milestones, and level are stored on your Mac and never sent to a server.
