Heimdall Focus

Block sites, set schedules and limits, and hide distracting YouTube features.

Heimdall Focus is a local website blocker for Chrome. Add a site from the toolbar popup, choose when blocking should apply, and redirect blocked visits to a built-in block page. You can also hide specific YouTube surfaces such as Shorts, comments, recommendations, thumbnails, the top bar, end cards, and autoplay. What Heimdall Focus does: - adds website targets from the popup or settings page - supports permanent blocks, weekly schedules, and daily usage limits - includes bundled categories for social, video, news, gaming, and shopping sites - treats example.com and www.example.com as the same host while keeping other subdomains separate - hides selected YouTube features without blocking all of YouTube - shows local attempt counts on the block page What Heimdall Focus does not do: - it does not use a remote server - it does not require an account - it does not include analytics or advertising - it does not send browsing activity to a backend
