How we know

FirstSited records what new websites are built with, usually within a day of going live. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one to detect its tech stack. This page is what we saw on 8 September 2026; the live site may have changed since.

Every technology below links to its own page: which other new sites launched with it. Watch any of them and get every new site that uses it as it goes live, from £15 a month.

Spot a mistake? If a technology shown here is wrong or out of date, email [email protected] and we'll review it.
