About UserAgent

UserAgent.App is a REST API that parses raw browser user agent strings into structured data. A GET request with a user agent string returns fields covering client summary, browser family and version, operating system family and version, rendering engine, device type (mobile, tablet, or desktop), device brand, and bot detection details including bot name, category, and vendor.

The service is aimed at developers and DevOps teams who need to identify visitor browsers, devices, and operating systems for purposes such as analytics, security, and targeting. Access is over HTTPS, with API usage logs and IP whitelisting available, and support is provided by email.

Pricing is tiered by monthly request volume and concurrency, with both monthly and yearly (20% discount) billing options. Plans range from a free tier (5,000 requests/mo, 1 concurrent request) up to a Grand tier ($55/mo for 6,000,000 requests/mo, 50 concurrent requests), with all paid and free tiers including full parsing, HTTPS encryption, and email support. Custom enterprise and large-volume plans with discounts and SLAs are available on request.
