YouTube blocker for desktop
Block YouTube on your computer, and mean it
Free forever for 5 sites · or try Pro free for 14 days
The short answer
Talysman blocks youtube.com across Chrome and Firefox on Windows, macOS and Linux, blocks the desktop apps that would route around it, and closes browsers that can't enforce the list instead of leaving them open as the obvious workaround. Setup takes about two minutes.
What makes it hold is the unblock: turning focus off early requires a paired USB drive to be plugged into the computer. Leave the drive in another room and YouTube stays gone until the session ends — not until you change your mind. YouTube plus four more sites fits in the free tier, with no card.
Block YouTube in about two minutes
Install and pair a drive
Download Talysman for your platform and add the Chrome or Firefox extension. Plug in any USB drive you own and pair it — that drive is now the key for this computer.
Add youtube.com to the blocklist
Add the domain and anything that would stand in for it later that afternoon — reddit.com, x.com, whatever your particular version is. Five sites are free.
Start a session, then unplug the key
Set a length and start. Take the drive out of the machine and leave it somewhere that costs you a walk. That step is not optional; it's the entire mechanism.
What blocked actually looks like
Four things happen, and only the last one is unusual.
- In the browser
youtube.com stops loading in Chrome and Firefox. The block page doesn't even receive which address was requested — your blocklist is turned into browser-native rules and the extension never sees your browsing.
- In other browsers
A browser without the extension gets closed during a locked session rather than left running as the unguarded door.
- In desktop apps
The apps on your list — a desktop client, Discord, Steam — are blocked as apps, so the distraction can't just change shape.
- When you try to undo it
You click End session. The service checks for your paired key, finds nothing plugged in, and declines. The drive is in the kitchen. You go back to work.
About watching YouTube for work
Blocking is domain-level. youtube.com is either blocked or it isn't — there's no way to permit one tutorial and refuse the homepage, and any tool that claims otherwise is deciding for you what counts as research.
If your work genuinely needs a narrow set of sites, the better fit is allow-only mode: block everything, then list the handful of tools the job actually requires. It's a harder setting than a blocklist, and it's the one that turns a personal computer into a work computer without buying a second computer.
The parts that matter after week one
Anyone can block YouTube once. These are the things that decide whether it's still blocked in March.
Recurring windows arm themselves
Schedule your two best hours and the block starts without you — even if the app is closed and you never remembered to press start. That's Pro.
Quitting the app changes nothing
Enforcement is a privileged background service. Closing the window, killing the process, or rebooting all leave the session running.
Uninstalling is key-gated
The uninstaller refuses to remove the service mid-session unless a paired key is present, so “uninstall” isn't the unblock button.
Your history stays yours
The extension never receives the URLs you visit, your history, page content, or search terms, and makes no requests of its own.
Frequently asked questions
Does it block the YouTube desktop app too?
App blocking covers desktop applications you add to the list, so a desktop client isn't a way around the site block. App blocking is a Pro feature; website blocking is free.
Can I block YouTube but allow one channel or one video?
No — blocking works at the domain level, so youtube.com is blocked or it isn't. If you need a small set of work tools and nothing else, use allow-only mode instead.
Which browsers are supported?
Chrome and Firefox have extensions. During a locked session, any browser without one is closed rather than left as an open door, so an un-extended browser isn't a workaround — it's just a browser you can't use right now.
Is blocking YouTube free?
Yes. Free covers 5 blocked websites, unlimited manual sessions and the key requirement, with no card. Recurring schedules and desktop app blocking are Pro, free for 14 days — see pricing.
Block YouTube for one real workday
