Our verdict on Focuser

Focuser is a free, open-source desktop blocker for people who want to limit distracting websites and applications. It is aimed especially at technical desktop users who prefer detailed controls and local configuration. Website rules can target domains, keywords, wildcards, URL paths, or the whole internet, while application rules can use executable names, paths, or window titles. The product supports Windows, macOS, Linux, and browser extensions for Chrome-based browsers and Firefox.

Its strongest area is control depth. Weekly schedules provide day-and-hour rules, while locked sessions prevent block lists from being edited or disabled until a timer expires. Pomodoro sessions have configurable work and break phases, and daily allowances can limit time on selected websites and applications. Pre-made block lists and bulk imports from text or JSON help with larger rule sets. Blocking statistics and attempt tracking add a way to review activity over time.

Focuser also takes a deliberately local approach: configuration and statistics are stored locally, with no accounts, cloud sync, or telemetry. That fits users who want private controls, but it also means the product does not provide cloud synchronization across devices. There are no mobile apps, so it is focused on desktop workflows. Windows is described as tested and working, while macOS and Linux builds exist but need real-world testing. Choose Focuser if granular desktop blocking, locked sessions, and local storage matter most; choose an alternative if mobile coverage or synchronized settings are essential.
