It's a reasonable instinct: before paying for anything, you want a free way to block YouTube on a Chromebook. There are a few free options, and it's worth knowing exactly what they do and don't do on a school-managed device before you spend a dime — or a lot of evenings.
The free options, honestly
- Router-level blocking (free). You can block youtube.com on many home routers. But it's all-or-nothing: it kills the videos teachers assign too, and it only works on your home Wi-Fi. This is the classic trap behind why blocking all of YouTube isn't the answer.
- Google Family Link (free). Genuinely good on devices you own — but on a school Chromebook it usually can't attach to the school account.
- Free "block site" extensions. These can block whole domains, so again it's all-of-YouTube-or-none, and a kid signed into the device can often remove them.
- Turning off Wi-Fi (free). Stops the distraction and the homework at the same time.
Why "free" often costs you more
The hidden cost of the free routes is your time and the broken homework. You end up toggling blocks on and off all evening, fielding "the teacher's video won't play," and refereeing the same fight you were trying to end. On a school Chromebook, the free tools also tend to get overridden or removed.
When a small paid tool is worth it
If what you actually want is "the assigned video plays, the feed doesn't," no free option does that cleanly on a school Chromebook — because telling schoolwork apart from entertainment is the hard part. That's the gap Homework Mode fills, and it costs less than a school lunch with a 14-day free trial (no card up front), so you can watch it work before paying.

Frequently asked questions
Is there a completely free way to block YouTube on a school Chromebook?
You can block all of YouTube for free via a router or extension, but that breaks assigned videos and is easy to undo. There's no free option that reliably allows schoolwork videos while blocking the feed.
Does blocking YouTube on the router work?
Only on your home Wi-Fi, and only all-or-nothing — it can't separate lessons from entertainment, so it breaks homework videos too.
Why not just use a free site blocker?
Free site blockers work at the domain level (all of YouTube or none) and can often be removed by a kid signed into the device, so they rarely hold up on a school Chromebook.
