Changelog
New updates and improvements to SiteBlocker.
Section blocking: Shorts and Reels, without blocking the site
Block one part of a site without blocking the whole thing. Switch off YouTube Shorts, Instagram Reels, Reddit r/popular or Facebook Reels and the rest of the site keeps working — their buttons and thumbnails are hidden too, so they are not dangled in front of you. TikTok and X get their For You feeds hidden. Free for everyone. This release also fixes signing up and upgrading from inside the extension, the billing portal, and the Keywords on/off switch.
Calendar-triggered blocking
Focus Mode can now start by itself during your calendar events. Connect Google Calendar in one click or paste any ICS link, then choose whether every event counts or only the ones matching a keyword, and whether the session can be ended early. Fetching and recurrence handling happen on our servers, so your calendar tokens never reach the browser. A Pro feature.
Locked Mode, time budgets & a faster interface
v4.1 introduces Locked Mode — focus sessions you can't quit halfway through, with an optional accountability-partner email if you unlock early. It also adds per-site daily time budgets, a dedicated Block List tab that makes managing sites faster, a redesigned interface, and support for 8 languages.
SiteBlocker Pro: keyword blocking & full insights
A major release introducing the Pro plan — keyword blocking (block pages by words in the URL, title, or content) and a full insights dashboard with weekly activity, top blocked sites, focus analytics, and an hourly distraction heatmap. Core blocking stays free for everyone. Also includes a redesigned marketing site, account management, and cross-device sync.
Improved Extension: whole overhaul
We've upgraded our entire extension to have personal accounts. The extension is now completely free. We also introduced Firefox support, something we had in the works for a long time.
New Feature: Dark Mode
We added dark mode to the extension.
