They simply relay datagrams, which is what makes UDP proxies suitable for fast, real-time transmission. UDP proxies stay protocol agnostic, forwarding almost any packet without inspection.
UDP proxies differ sharply from http proxies. HTTP proxies were designed for web traffic, while UDP proxies are designed to move UDP packets. In practice, almost every UDP proxy today is a SOCKS5 proxy that implements the UDP ASSOCIATE command.

We work with thousands of clients who run web scraping, market research, ad verification, SEO monitoring, and large-scale automation projects.
