The fastest way in is a domain. Periphery finds every app tied to it: hostnames that contain it, pages that mention it, and pages with an email address on it.
1

Type a domain

In the search bar, type a domain such as acme.com and press search. A pasted URL works too; subdomains and paths are stripped down to the registrable domain. See Domain search.

Read a result

Each result shows:
  • Hostname, the app’s address. Click it to open the app page.
  • Title of the page, or the hostname again when there is none.
  • Snippet of the page text with your matching words highlighted, when the match is in the page text.
  • Provider chip, the platform the app runs on.
  • Status badge, the HTTP status the app last answered with. Green is 2xx, blue 3xx, orange 4xx, red 5xx.
  • seen, how long ago the app was last visited and found alive.
  • emails, how many addresses were found on the page.
  • creds, the names of the detectors that found a verified credential, when any did.

Narrow down

Clicking a provider chip or a status badge adds the matching filter to your query. Clicking a favicon adds a faviconHash: filter for apps with the same favicon. Or type filters directly: acme.com provider:vercel status:200. The full list is in the filter reference.

Open an app

Click a hostname to see the full record: the screenshot, every email address, the credential findings, the extracted text, and the raw HTML snapshot.

Views and pages

The list and grid toggle switches between rows with a thumbnail and cards with a large screenshot. Results come 50 per page; prev and next move between pages, and the count line says which results you are looking at.

When nothing matches

A domain search with no results offers the domain’s name as a keyword search instead: acme.com becomes acme, which matches titles and page text that mention it. Any other empty result suggests trying a domain or a filter combination.
Searches are unlimited on every plan. The console allows one search per second, so a rapid series of searches or page changes may ask you to slow down. See Plans and limits.
