Ikizen vs LeechBlock NG
Choose LeechBlock NG if your main problem is controlling when and how long you can visit particular websites. Consider Ikizen if you also want your goals, tasks, habits and code activity in front of you whenever you open a new tab.
We make Ikizen. We checked LeechBlock's official documentation on 2 October 2026. Both products provide free desktop website blocking. Paying is not a prerequisite for getting useful rules.
Where LeechBlock fits
LeechBlock NG supports up to 30 groups of sites, each with its own schedule. You can set a time allowance such as ten minutes per hour, combine allowances with time windows, or start an immediate lockdown. Its patterns support wildcards and exceptions. LeechBlock feature overview.
Its options go further into blocking details: page paths, keywords, referring sites, delays, passwords and temporary overrides. If your rule is "allow this section of a site, but only for a few minutes during lunch," those controls are worth examining. LeechBlock documentation.
That is a reason to choose LeechBlock. We would not ask you to replace a working set of rules just to put a different logo in your toolbar.
Where Ikizen fits
Ikizen is a focus system for entrepreneurs and makers who have already quit social media. Blocking protects time. The dashboard reminds you what you meant to do with it.
You can put your current goals beside Todoist tasks and tracked habits, then connect GitHub and Bitbucket contributions, a commit streak and deployment status. Add your own links, images and quotes. Move or resize the widgets as your work changes.
For website blocking, Ikizen lets you choose times, days and bypass difficulty. Your inspiration images and reminders can appear on block screens. It also has controls for hiding YouTube Shorts, quieting tabs that change their title and limiting your tab count.
If detailed time allowances are the reason you installed LeechBlock, keep that requirement central when evaluating Ikizen. The contribution wall is useful for a different job.
Free in one browser, paid across devices
All Ikizen desktop widgets and focus tools work without an Ikizen account. The dashboard is stored locally. Optional integrations contact the services you connect, and uploaded images are stored on Ikizen servers.
An optional paid plan takes your setup across browsers and onto your phone, with cloud backup and the Android and iOS companion apps. Phone website rules need an existing paid account and desktop setup. iOS uses Screen Time in Safari with a system block page and no bypass. These rules do not block native phone apps.
LeechBlock offers settings export and import, including browser sync storage. If moving blocking rules between compatible browsers is all you need, check those options before buying anything. LeechBlock export and import documentation.
Start with the problem you still have
If LeechBlock already keeps you away from distracting sites, the next question is whether you forget your priorities when you open another tab. That is where a dashboard with a few chosen goals may help.
You can evaluate Ikizen's dashboard while keeping LeechBlock for blocking. Give one extension responsibility for each site's blocking rules so overlapping schedules are easier to understand.
Browser extensions depend on staying enabled and having the required permissions. Ikizen's desktop blocking is a commitment tool you control, not a guarantee that you cannot undo your own setup.
