Three more platforms joined [Scan](/scan) today, each with its own page showing
a single preview instead of the full wall of cards, with the checks, the
findings and enough writing about that platform to be worth landing on from a
search:

* [Mastodon](/scan/mastodon) — the expanded-link card, image above provider,
  two-line title and clipped description, contributed by
  [@vansh-nagar](https://github.com/vansh-nagar).
* [Snapchat](/scan/snapchat) — the chat card, full-width image with title and
  domain in a rounded bubble, contributed by
  [@MayurK-cmd](https://github.com/MayurK-cmd).
* [Signal](/scan/signal) — the chat-style card with image, title, description
  and hostname, contributed by
  [@mdsahilnoob](https://github.com/mdsahilnoob).
