Best Forward Proxy Software in 2026

Forward proxy software routes client requests toward online services, with options to compare for traffic handling and control. Compared on deployment, proxy protocols, and concurrent connections, the entries also show whether they offer SSL inspection, user authentication, and web filtering. Check free-plan availability and paid-from pricing as part of the comparison. Cloudflare Gateway, mitmproxy, and 3proxy are among the products included, alongside Privoxy and Squid. Weigh the listed protocols and controls against the needs of your environment, including how you plan to deploy the proxy and manage access to web traffic.
