The blocker without an off switch

A website blocker you actually can't disable.

Every other blocker has an off switch — a pause button, a password you set, a one-click uninstall. You'll find it at the exact moment you shouldn't. Threshold hands the key to an accountability partner instead, with a 72-hour wait on every change. It's free, no account, for Chrome, Edge, Firefox and Safari.

"Typical blockers" describes the common pattern across self-controlled tools; individual products differ.

An off switch you control isn't a lock

The whole problem is the moment — tired, late, alone — when the part of you that set the rule is nowhere to be found. A blocker you can disable is only as strong as that moment, and that moment always wins.

So Threshold removes the switch from your hands. You pick the blocklist while you're clear-headed. After that, the only way to change anything is to ask your partner, and an approval still waits 72 hours before it takes effect — long enough for the urge to pass and for them to say no.

We're honest about the limit: a determined person can open another browser. Threshold isn't a wall around the whole internet — it's a threshold, a line you chose, with a real person standing on the other side of it.

Common questions

What actually stops me from disabling it?
There's no control that turns it off. Every change — remove a site, change partner, uninstall — is a request your partner approves or denies, and approvals wait 72 hours. There's no password to reset, because the code is random and hashed on your device.
Is it free?
Yes — the blocker, the partner flow, and the 72-hour wait are all free, with no account.
Which browsers does it work on?
Chrome, Edge, Firefox and Safari.
