Platform
The HTTP Platform response header is an unofficial header identifying the hosting platform or infrastructure serving the response.
Usage
The Platform header is sent by managed hosting providers to expose which platform backs a given site. Hostinger is the dominant sender, using the header to identify its hPanel-based hosting environment. The value "hostinger" appears on the vast majority of sites including this header.
Platforms send the header as part of a broader set of
infrastructure-identifying headers. On Hostinger, Platform often
appears alongside X-Powered-By,
Panel,
x-hcdn-cache-status, and X-Hostinger-Node. Together these headers
describe the full stack: platform, control panel, CDN cache status,
and edge node.
Values
hostinger
Indicates the response is served from Hostinger's hosting infrastructure. This is by far the most common value, present on nearly all sites sending the header.
Other platform identifiers
Some infrastructure providers and smaller hosting platforms use the header with their own identifiers. Values such as "By TurboCloud" and similar strings indicate platform-specific branding rather than a standardized format.
Example
A response from a site hosted on Hostinger. The value identifies the platform directly by name, confirming the request was served from Hostinger's infrastructure.
Platform: hostinger
A response from a smaller or custom hosting platform branding its value differently.
Platform: By TurboCloud
Takeaway
The Platform header identifies the hosting platform backing the server, primarily sent by Hostinger and closely related infrastructure alongside other Hostinger-specific response headers.
