FastWeb Accelerator

FastWeb does two things: rescues broken links and speeds up working ones. When you hit a dead page (404, 502, timeout), FastWeb instantly offers the cached version from Google — one click and you're reading the content that disappeared.

What is FastWeb Accelerator?

FastWeb does two things: rescues broken links and speeds up working ones. When you hit a dead page (404, 502, timeout), FastWeb instantly offers the cached version from Google — one click and you're reading the content that disappeared. For live pages, it uses smart prefetching: hover over a link for 65ms and the page starts loading in the background before you click, shaving 300ms+ off every navigation. Zero telemetry. No accounts. No data collection. Open source.
