Google's User-Agent Client Hints is a modern web API designed to provide websites with detailed, privacy-conscious information about a user's browser and device. Instead of relying on traditional User-Agent strings, which can be spoofed or are overly verbose, Client Hints offers a standardized way for servers to receive relevant device and platform data in a more controlled and secure manner, improving both user privacy and website performance.
