User Agents

User Agents used by Brave clients

Brave uses various User-Agent request headers and user agent client hints (Sec-CH-UA) on various platforms. The exact values vary depending on what version of the browser you're using and your OS architecture. Also see https://github.com/brave/brave-browser/wiki/Detecting-Brave-(for-Websites).

Notes

2. Chromium applies GREASE to Client Hints.
