Best LeechBlock alternative for Mac
LeechBlock NG is the better pick if you want a free open-source Chrome rule engine with per-hour schedules and regex blocksets. Focuh is the free Mac and web ADHD todo list if the leak is the day itself: Today next to Google Calendar, loops that wait until you pull them, and Mac blocking that also covers apps and other browsers.
Free. Early beta. No subscription.
Where LeechBlock wins
LeechBlock NG is a rule engine for Chrome, and a very good one. It gives you up to 30 independent blocksets, each with its own list of sites, its own per-day and per-hour schedule, a daily time budget, URL-pattern and regex matching, and a password or delay lock so you cannot casually loosen a rule mid-afternoon. If you want Reddit allowed from 12:00 to 12:30 on weekdays only, LeechBlock can say exactly that. It is also free and open source, so anyone can audit what it does, and it runs entirely inside the browser with no account. If you enjoy configuring software and your blocking needs are genuinely complex, LeechBlock is the sharper tool. Focuh has no regex, no per-hour schedule grid and no 30-blockset model, and it is not open source.
Where Focuh wins
Focuh is an ADHD todo list for Mac and web. Today sits next to Google Calendar. Week is the week. Loops are standing to-dos with no date: you pull a copy onto today and the loop stays. Goals are the one win for the horizon. Blocking is part of the focus session, not a separate settings page: pick the task, start the timer, and the blocklist holds until you stop. On Mac that blocklist is enforced at the system level, so it covers Safari, Firefox, Arc and Chrome at once, and it covers apps as well, so Slack, Discord and Messages go quiet too. LeechBlock is a Chrome extension and nothing more: switch browsers or open a native app and its block is gone. LeechBlock also has no todo list, no calendar and no timer. Focuh syncs the same list between the Mac app and the web app, so the plan is there on any machine even where the Mac blocker is not.
Price: LeechBlock NG is free and open source, with no paid tier. Focuh is free. Early beta. No subscription.
Who should pick which
Pick LeechBlock if the leak is Chrome, you want granular per-hour schedules and regex rules, you value open-source code, and you already have a list and a calendar you like. Pick Focuh if you are on Mac and the leak is the day itself: you need Today next to GCal, loops that wait until you pull them, and a blocker that holds across every browser and app on the machine during a session. Plenty of people run both. LeechBlock for the always-on Chrome schedule, Focuh for the everyday session where knowing what to work on matters as much as the block.
