Website anti-scraping mechanisms often identify bots by detecting fixed User-Agents, leading to IP bans. This tool bulk generates random yet realistic User-Agent strings based on actual browser versions, operating systems, and device models. By simulating diverse user environments, it significantly reduces the risk of detection. A User-Agent is a field in the HTTP request header that identifies the client software, OS, and device type, allowing servers to return appropriate content or enforce access controls.
Q: Do the generated User-Agents include outdated or invalid versions?
A: No. Our tool's database is continuously updated to include only valid versions of current mainstream browsers, such as Chrome 120+ and Firefox 115+, ensuring high usability.
Q: What is the maximum number of User-Agents I can generate at once?
A: 50. If you need more, we recommend generating them in batches or using them in combination with proxy IP rotation.
Please comply with website robots.txt protocols and terms of service. When generating more than 20 requests in bulk, it is recommended to add request intervals. The results are for technical research purposes only and should not be used for illegal scraping.
We recommend combining UA generation with an IP proxy pool and request delay settings. For example, rotate your UA and IP every 100 requests. A typical setup: generate 10 Chrome UAs and pair them with 10 proxy IPs, rotating them sequentially to effectively bypass rate limiting and frequency detection. Note that mobile UAs should be matched with corresponding device resolutions and touch event simulations.
