FastWeb shows official alternate domains, your bookmarks, and accelerates link loading — right on Google, Bing, DuckDuckGo, and Yandex search pages. Why FastWeb? Some websites change domains, get blocked, or move to new addresses. FastWeb keeps a map of domain-to-alternate relationships so you never hit a dead end in search results. One click takes you to the working version. What it does

Alternate domains — when a search result matches a domain in your list, FastWeb shows its official mirrors and alternates in a compact panel
Smart bookmarks — scans your bookmarks and shows relevant ones alongside search results
Link acceleration — warms up DNS/TCP/TLS for top results on hover. Pages load noticeably faster when you click
Domain bundles — curated bundle of popular alternates for your locale, auto-updates daily. Add your own or import JSON
Flexible display — full panel or compact icon-only badge

Getting started

Install FastWeb
Click the toolbar icon to open settings (or use the sidebar)
Load the starter bundle or add your own domains
Search on any supported engine — alternates appear automatically
Pin the icon to the toolbar for quick access

Privacy-first

All data stays in your browser — nothing is sent to any server except the optional daily bundle sync
No analytics, no tracking, no telemetry
Prefetch only warms up connections (DNS/TCP/TLS), never fetches page content
Bookmark data is read locally, never transmitted
