The short answer

Why people look for a BlockSite alternative
The reasons that come up most are price, privacy and permissions. BlockSite sells paid plans on its website. Its Chrome Web Store listing discloses that it handles web history, and its manifest requests 12 permissions plus access to every site. If none of that bothers you, BlockSite is a capable tool with more features than most alternatives. If it does, the options below take a different approach.
1. Site Blocker
Best for: People who want a free blocker whose developer collects nothing, with precise rules.
Site Blocker blocks whole sites, single pages, keywords and regex patterns, redirects distracting sites to useful ones, and has a whitelist-only Focus Mode with a timer. It has no account and no paid tier, and its store listing discloses no data collection.
Where it falls short: It is new and small, with 3,000 users. It has no schedules, no daily time limits, no password lock and no mobile app.
Site Blocker on the Chrome Web Store2. LeechBlock NG
Best for: Power users who want schedules and time limits without giving up privacy.
LeechBlock NG is a free, open-source blocker from an independent developer. You can create up to 30 sets of sites, each with its own days, time periods and time limits, add a password or access code to the options page, and delay access instead of blocking outright. Its listing states it does not collect or use your data.
Where it falls short: It has the most settings of any tool here, so setup takes longer. Its listing does not mention redirects or usage statistics.
LeechBlock NG on the Chrome Web Store3. StayFocusd
Best for: People who want a daily time allowance and a block they cannot switch off.
StayFocusd, published by Sensor Tower, gives you a maximum time per day on the sites you list, then blocks them. It adds active days and hours, the Nuclear Option, and Require Challenge, which makes you complete a task before settings can change.
Where it falls short: Its store listing discloses that it handles web history, user activity and website content. Its listing does not mention regex rules or redirects.
StayFocusd on the Chrome Web Store4. AppBlock
Best for: People who already use AppBlock on their phone and want the same on desktop.
AppBlock, from MobileSoft, is best known as a phone app that blocks apps as well as websites. Its Chrome extension blocks websites and keywords, supports schedules by day and time, and has a Quick Block timer for temporary blocking.
Where it falls short: Its store listing discloses that it handles personally identifiable information and user activity. The Chrome extension was last updated in March 2025.
AppBlock on the Chrome Web StoreHow to switch from BlockSite
- Open BlockSite's settings and note the sites and keywords on your blocklist.
- Install the alternative from the Chrome Web Store and add the same sites. In Site Blocker you can also block from the toolbar popup while you are on a site.
- Recreate anything else you rely on, such as redirects or a focus timer.
- Remove BlockSite from chrome://extensions so two blockers are not running at once.
