How to Block Twitch on Chrome (in ways that actually stick)

Twitch weaponizes FOMO better than any site on the internet, because streams are live: close the tab and you're not pausing content, you're leaving a room where something might happen. Add chat moving in real time and a streamer who might say your name, and you have a distraction that feels like a social obligation.

Option 1: Block Twitch manually (free, but you hold the keys)

Chrome has no built-in "block this website" button for normal installs, so the manual route means editing your computer's hosts file: point the domain at 127.0.0.1 and the site stops resolving. It costs nothing and needs no software.

Twitch keeps streams running in picture-in-picture and miniplayers, so 'just closing the tab' often doesn't even stop the audio. VOD links and clips.twitch.tv survive naive domain blocks.

The deeper problem is structural: any block you can set up in two minutes, you can undo in thirty seconds, and the moment you'll want to undo it is precisely the moment it exists for. Manual blocks are honor-system locks.

Option 2: A list-based blocker extension

Extensions like BlockSite or StayFocusd let you add the domain to a list, which beats the hosts file on convenience. Two weaknesses remain: the list is binary (the whole domain is blocked even when part of it is genuinely useful for your work), and the off switch is two clicks away in your extensions menu. List blockers stop the absent-minded visit; they rarely survive a motivated one.

Option 3: Block Twitch with an AI that knows what you're working on

Focus AI works differently: you type what you're doing ("finish the calculus problem set"), pick a duration, and lock in. During the session, the AI reads every page you open against that task. Twitch gets blocked when it doesn't serve the work, and the block page shows your own promise back to you, with an escape-attempt counter and a running tally of the time you've saved.

1. Install Focus AI from the Chrome Web Store (free, no account needed).
2. Type the task you're actually here to do and choose a session length.
3. Click Lock me in. Twitch now hits a wall for exactly that long, and quitting early means typing your surrender letter by letter.

Two details matter for live streaming sites specifically: the AI evaluates pages rather than domains, so the useful corners of the internet stay reachable while the feed does not. And every time you walk away from the block page, the win is stamped and timed: resisting Twitch becomes a streak you can watch grow instead of a sacrifice you silently endure.
