Automatic Blocking
A website blocker that turns on automatically when you start to work.
The best blocker is the one you never have to remember. GoFlow blocks your sites the instant a focus round begins and steps aside the instant you break. No switch, no daily setup, no all-day lockout.
GoFlow at goflow.space is a website blocker that turns on automatically. The block is tied to your focus round: it starts the moment a work round begins and stops the moment you break or finish. You set your sites once, then never flip a switch. Free, on-device, no account.
Let the block run itself
Set your sites once. The blocking is automatic after that.
Open GoFlow freeWhy "automatic" is the whole point
Think about when a blocker actually has to work. It is the moment you hit something hard, your focus slips, and your hand reaches for the same site it always reaches for. That is the exact moment you will not choose to turn a blocker on. So a blocker that waits for you to flip it does nothing when you need it most.
An automatic blocker removes the choice. The block is already on because the work is already running. You decided once, when you were calm, to keep those sites out of your work rounds. After that the tool just holds the line for you.
What makes GoFlow's blocking automatic?
GoFlow ties blocking to the timer, not to a separate schedule. Here is the full loop:
- You start a focus round. Pomodoro, fixed, or open. The free Focus Guard extension sees the round begin and blocks every site on your list.
- You stay in the work. The sites that usually pull you away are simply not reachable. You did not have to do anything.
- You break or finish. The block lifts on its own. The sites come back so you can use them between rounds.
Because the block follows the round, there is no schedule to manage and no end time to set. Work a 25-minute round and the block is 25 minutes. Work a 90-minute round and it is 90. The block always matches the work.
How is this different from scheduled or always-on blockers?
Most blockers fall into two camps, and both have a flaw the automatic approach avoids.
| Approach | The flaw | GoFlow |
|---|---|---|
| Manual switch | You forget, or skip it "just this once" | No switch, it is automatic |
| Scheduled hours | Real focus rarely fits a fixed clock | Matches your actual round |
| Always-on lockout | Locks you out of tools you need too | Open between rounds and on breaks |
The result is a blocker that is strict when you are working and out of the way when you are not.
What can you block, and where?
Any site that pulls you off task: social feeds, news, video, shopping, forums, or a single page. You edit the blocklist inside GoFlow and it is stored on your device. The blocking runs through the free Focus Guard extension on desktop Chrome, Edge, and Brave. Being honest about the limits: it blocks desktop websites, not phone apps or your operating system, and your list does not sync across devices. See the full setup on the website blocker page.
Free and private
The Focus Guard extension is free, with no subscription and no account. Your blocklist never leaves your machine. GoFlow does not track your browsing. The timer and your stats work in any browser, and you can install GoFlow as a PWA to run it offline.
Stop deciding to focus. Just start.
The block turns on with your round, every time.

How does the website blocker turn on automatically?
It is tied to your focus round. When you start a work round in GoFlow, the Focus Guard extension blocks your sites. When the round ends or you break, they reopen. There is no switch to flip.
Does it lock me out all day?
No. Sites are blocked only while a work round runs. Between rounds and on breaks they are open, so you can still use the tools you need.
Do I have to set it up every day?
No. You build your blocklist once inside GoFlow. After that the blocking is automatic on every round.
Is it free?
Yes. The Focus Guard extension is free, with no account and no subscription, and your blocklist stays on your device.
