Detect and parse Browser, Engine, OS, CPU, and Device type/model from an user-agent string.
Paste a user agent string in the input, or click 'Use my browser' to parse your current browser's UA.
View parsed results: Browser (name, version), Engine, OS, Device (model, vendor, type), CPU architecture.
Copy the UA string or parsed values for debugging, analytics, or device detection logic.

A user-agent parser converts raw User-Agent strings into structured data: Browser (name, version), Engine, OS, Device (model, vendor, type), and CPU. The User-Agent header is sent with every HTTP request and identifies the client. This user agent parser online uses ua-parser-js logic to detect browsers (Chrome, Safari, Firefox, Edge), engines (Blink, WebKit, Gecko), OS (Windows, Mac OS, Linux, Android, iOS), devices (mobile, tablet, desktop), and CPU architecture.
Use it as a user agent parser example, or to validate UA parsing in user agent parser python, user agent parser java, user agent parser typescript, user agent parser npm, user agent parser c# projects. ua-parser-js on npm provides the same detection for Node.js and browser.
Use 'Use my browser' to instantly parse your current UA. For server-side parsing in Node.js, use ua-parser-js npm package. For Python, try user-agents or python-user-agents.
This user agent parser online works entirely in the browser. No server uploads. Paste any UA string or use your current browser's UA. Output matches ua-parser-js format: browser.name, browser.version, engine.name, os.name, os.version, device.model, device.vendor, device.type, cpu.architecture.
For programmatic parsing: npm has ua-parser-js and my-ua-parser. Python has user-agents and python-user-agents. Java has User-Agent-Utils. C# has UAParser. Use this tool as a user agent parser example to validate UA strings across implementations.
