Claude Blocker is a free Chrome add-on designed to help users enhance their productivity by blocking distracting websites like X and YouTube. This tool allows access to these platforms only when the user is actively working on a Claude Code terminal, promoting a focused work environment. Ideal for those who find themselves easily sidetracked, Claude Blocker encourages a disciplined approach to work by integrating seamlessly into the user's workflow.

To set up Claude Blocker, users need to run the command `npx claude-blocker` in a terminal, which initializes the necessary hook and server. This open-source tool not only provides a practical solution for managing distractions but also allows users to customize their experience. By limiting access to non-work-related sites, Claude Blocker helps users maintain concentration and improve their overall productivity.
