# What is Periphery

> Visibility beyond your perimeter. Periphery indexes what publicly reachable web apps on hosting platforms expose to any visitor, and lets you search it.

Periphery is a search console over web applications that anyone can reach on hosting and platform providers such as Vercel, Netlify, Lovable, Railway, and Heroku. For each application it records what an anonymous visitor sees, and lets you search across all of it.

## What a record holds

Each indexed application, an *app* in Periphery, is one hostname on a provider suffix, such as `acme-dashboard.vercel.app`. Its record holds:

* The page title, the visible text, and a screenshot.
* The HTTP status the app last answered with.
* The favicon and its hash, for finding clones.
* Email addresses found on the page.
* Strings shaped like API keys or secrets found in the page source, and whether they were verified as live.
* When the app was first and last seen.

Everything comes from public URLs, fetched without authentication. Periphery never bypasses access controls or exploits anything; it records what is already visible.

## Who it is for

* **Security teams** checking what their organisation has left exposed on platforms outside the corporate perimeter.
* **Researchers** looking for a pattern across many apps: a leaked key type, a phishing kit, a vulnerable template.
* **Platform operators** who want to see what is running under their suffixes.
