USER-AGENT PARSER
Decode user-agent strings to identify browsers, operating systems, devices, and rendering engines. Every HTTP request includes a user-agent header that reveals technical details about the client. This tool parses that information into a structured, readable format for testing, debugging, and analytics.
Parse and analyze browser user agent strings to detect browser, OS, and device information.
Browser detection, OS identification, device type, bot detection.
Important: While user-agent strings are helpful for analytics and optimization, they should never be used for security decisions. User-agents can easily be spoofed or modified by users, bots, or malicious actors. For security-critical operations, always use server-side validation and proper authentication mechanisms. This tool uses the widely-trusted ua-parser-js library, which is maintained by the open-source community and regularly updated to recognize new browsers and devices.
