FastWeb — Search Accelerator by 301.st

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

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
