User Agent String Parser
Parse User-Agent strings from HTTP request headers to extract detailed technical information, including browser, operating system, and device type.
When conducting automated testing, web scraping, or simulating different browser environments, a static User-Agent is easily identified and restricted. The core function of this tool is to quickly generate a large number of random, realistic User-Agent strings. This makes your server-side requests appear as though they originate from various operating systems, devices, and browser versions. It works by parsing and combining the User-Agent formats of mainstream browsers and operating systems, randomly generating complete strings in standard formats like "Mozilla/5.0 (Platform; Device Info) Browser Engine/Version Application/Version".
Q: Can a User Agent generator bypass all anti-scraping mechanisms?
A: Not entirely. User-Agent rotation is only one of the most basic and easily identifiable anti-anti-scraping measures. Modern anti-scraping systems comprehensively check multiple characteristics, including IP addresses, request frequency, Cookies, JavaScript execution, and TLS fingerprints. Changing the User-Agent alone is insufficient against advanced anti-scraping strategies.
Q: How can I quickly generate a large number of Android mobile User-Agents?
A: First, select "Android" under "Platform", then choose "Mobile" under "Device Type". Finally, drag the quantity slider to the maximum value (e.g., 50) and click "Batch Generate".
Please use the content generated by this tool for legal testing, development, and educational purposes only. Do not use it for malicious scraping, attacks, or violating others' privacy and data rights. The generated User-Agents are strictly for simulating request headers and do not contain any personally identifiable information. Note that excessively frequent User-Agent rotation while requesting the same target may still result in detection and banning based on other characteristics like IP and behavioral patterns.
For professional web scraping or automated testing, we recommend combining User-Agent rotation with other strategies, such as: 1) using a proxy IP pool to distribute request sources; 2) controlling reasonable request intervals and rates; 3) simulating complete browser sessions (e.g., managing Cookies, executing JS). A typical User-Agent application example: in Python's requests library, assign the generated string to the 'User-Agent' field in the request headers, like `headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36'}`. Please note that some websites check the "reasonableness" of a User-Agent; strings that are too old or have mismatched version numbers may actually raise suspicion.
