About Userstack
What Does Userstack Do?
Userstack is a real-time User-Agent string parsing API that identifies browser, device, operating system, and crawler data from any user-agent string. It solves the problem of inaccurate device detection by providing instant, reliable JSON responses backed by a daily-updated proprietary database.
Who Is It For?
Userstack is built for developers, product teams, and marketing professionals who need to tailor content, detect crawlers, or optimize user experiences based on device and browser type. It is not designed for non-technical users who cannot integrate REST APIs.
Real Use Cases
Use Userstack for native app download prompts, tailored advertising, custom content delivery, spambot detection, and crawler protection. The API integrates in under 10 minutes using PHP, Python, Node.js, jQuery, Go, or Ruby.
