24 alternatives to Sanctuary
Site blockers on Chrome all run based on a freemium model, and i've always been annoyed by how I couldn't find one that had quite all of the features I need.

Because chrome extensions don't work. Blocking it natively makes it unbypassable, and having your agent gatekeep your focus is the ultimate cheat code.
