Privacy and permissions: the biggest difference
BlockSite's Chrome Web Store privacy section says it handles your web history, and its manifest requests 12 permissions, including cookies, scripting and webRequest, plus access to every website. Site Blocker requests 5 permissions and, like BlockSite, access to the sites you visit so it can block them. It has no account and no server of ours to send data to, and its store listing discloses no data collection. If you want a blocker whose developer never sees your browsing, that is the deciding factor.
Pricing: free vs freemium
Site Blocker includes every feature for free, with no premium tier. BlockSite is free to install and sells paid plans on its website; see blocksite.co for current prices.
Blocking rules: precision vs enforcement
Both extensions block websites and keywords. Site Blocker adds full regex patterns, so one rule such as youtube\.com/(shorts|feed) can block YouTube Shorts and feed pages while leaving individual videos open, and allow rules can carve exceptions out of a block. BlockSite leans towards enforcement, with schedules, usage limits and a built-in adult-content blocker.
Where BlockSite wins
BlockSite does more for people who need hard limits. It offers schedules by day and time, daily usage limits, password-protected settings, uninstall prevention, a built-in adult-content blocker, and apps for iOS and Android that sync your blocklist. Site Blocker has none of these today. If you need them, BlockSite is the better choice.
