App blocker vs website blocker: which should you use?

Published June 30, 2026

App blockers and website blockers solve different focus problems. A website blocker is useful when the browser is the distraction. An app blocker is useful when switching away from the work app is the distraction.

Most knowledge work needs both, but not always at the same intensity. The useful question is not which category is better. It is which layer protects the session you are trying to run.

Use a website blocker for browser drift

Website blockers are best for sessions where the browser is necessary but risky. You may need documentation, research, dashboards, or a web app, while still wanting to block feeds, video, shopping, and news.

The cleanest setup is domain-based: block the distracting domains, keep necessary work domains available, and avoid blocking the entire browser unless your task truly does not need it.

Use an app blocker for context switching

App blockers are best when the problem is leaving the work environment. If you start in a code editor and repeatedly jump into chat, mail, or a second browser profile, a website blocker only handles part of the behavior.

For app-level work, choose the apps that belong in the session. Everything else should require enough friction that you notice the switch before you lose the thread.

Combine both for deep work

Writing, coding, design, studying, and planning usually benefit from a combined rule: allowed apps plus blocked websites. The allowed apps define the workspace. The blocked websites remove common escape hatches inside the browser.

This is also easier to reason about than a giant always-on blocklist. Your rules match the current task, and the session has a clear beginning and end.

Choose by task, not ideology

For research, use lighter blocking so useful sources remain reachable. For execution, make the rules tighter. For admin work, block entertainment and feeds but leave mail, calendar, and documents open. For writing, keep only the editor and notes if possible.
