Your passkeys, on a phone you choose, under your control. PassKeyChain is an open-source Android app that holds passkeys you own, signs you in with them on your computer (by QR code) and on the phone itself, and lets you take them with you in open formats. No account, no cloud, no telemetry.

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 checked this one in full: its tech stack, DNS, security headers and page basics. This page is what we saw on 8 November 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.
