What is a User-Agent string?

It's a header string sent by your web browser that tells the website server what type of client (browser, OS, device) is making the request.

Why is my User-Agent important for web development?

Developers use the User-Agent to determine browser compatibility, deliver device-specific content, or serve mobile/desktop layouts.

Is the User-Agent a privacy risk?

While it identifies your software, it's generally considered low risk as it's a standard part of web traffic. Many browsers are simplifying their UAs for better privacy.
