Obstruct

Obstruct tries to help you focus by obstructing websites you’d prefer not to visit.

Choose the websites you want to obstruct and create custom rules defining when you want to block, allow or redirect them. Create unique rules for each website or copy rules from an entry you've already created. The extension doesn’t track you. All data is stored in the browser and it doesn’t log which sites you visit or the sites you choose to block. Supports both light and dark modes.
