FastWeb — Search Accelerator by 301.st

FastWeb shows official alternate links, your bookmarks, and connection warm-up — right on search results pages.

How it works When you search on Google, Bing, DuckDuckGo, or Yandex, FastWeb checks if any results have known alternate domains or mirrors. If so, a compact panel appears with direct links — saving you clicks and helping you reach the right site faster.

Key features

Alternate domains — maintain your own list or use the built-in bundle of known mirrors and official alternates
Bookmarks on SERP — see your related bookmarks right on the search page, no need to dig through folders
Acceleration Mode — optionally warm up DNS/TCP/TLS connections on hover so pages load faster when you click
Works on Google, Bing, DuckDuckGo, and Yandex
Dark and light theme with auto-detection
Import/export your domain list as JSON
Fully local — no accounts, no tracking, no data leaves your browser

Privacy FastWeb runs entirely in your browser. It does not collect, transmit, or store any personal data. The only network request the extension makes (beyond your normal browsing) is an optional daily check for bundle updates from a public GitHub repository. Acceleration Mode warms up connections but never downloads page content. See our full privacy policy for details.
