## What it is
uBlacklist is a browser extension that blocks specified sites from appearing in Google and other major search engine results. It supports match patterns and regular-expression rules, cloud sync of rulesets, and subscriptions to public blocklists.

## Use cases
- block spam sites from google search results
- hide seo spam from search engines
- subscribe to public search blocklists
- sync blocked site rules across devices
- filter search results with regex rules
- block sites on bing duckduckgo and brave

## When to choose
- you want to permanently hide specific domains from search results
- you need rule sync across browsers and devices
- you want to subscribe to community-maintained blocklists

## When to avoid
- you need to block sites network-wide rather than per-browser
- you use a search engine outside the supported list
