DeviceAtlas
HTTP Headers Parser
This tool checks what DeviceAtlas returns for HTTP headers.
You can paste in any headers (or just a
user-agent string) or click current browser headers to return results for your browser.
Client Hints headers are utilised where present, including hints from first and second requests.
Enter a User-Agent string or a set of HTTP headers, one per line, in the format.
