Block what distracts you
Block whole sites or just one section of a site, or allow only a list of sites. Start from ready-made starter packs and edit in bulk.
Focus mode
Stop yourself before the endless scroll. When you open a site on your list, the Toolbox extension pauses it and asks if that's how you want to spend your time right now.
- A block list and an allowed list, with starter packs and bulk editing
- A weekly schedule and strict sessions you can't cut short
- A calm pause screen you can tune, and stats on how often you turned back

A site blocker that asks before it blocks
When you open a distracting site, Toolbox shows a calm pause screen first. Go back, or continue for a set number of minutes.
On a schedule
Follow a weekly schedule, set daily time limits, and start strict sessions that can't be skipped.

The quick part runs in the Toolbox side panel, next to the page you're on. The full version is this page, on any computer you sign in on.
In the Toolbox extension
The extension pauses the sites on your list and lets you start a focus session from the side panel.

Is the Toolbox site blocker free?
Yes. It works on the free plan with a few limits, and you sign in with Google or your email, with no card. Blocking, the pause screen and focus sessions work on the free plan. One subscription unlocks every Toolbox tool; see the pricing page for what each plan includes.
Can I block a site only during work hours?
Yes. Set a weekly schedule, and the sites on your list are paused only during those hours.
Can I import my LeechBlock or BlockSite list?
Yes. Toolbox reads their exported lists, so your blocked sites come over in one go.
