HTTP vs SOCKS5 proxies: which protocol to use

Use whichever your software speaks; on most plans you do not have to choose, because the provider gives you both at one price. An HTTP proxy understands web requests; its tunnel can carry other TCP connections where the provider allows them, but not UDP. A SOCKS5 proxy relays any connection, UDP included, without interpreting it, and can look up site names for you, which keeps those lookups off your own network. Neither encrypts your traffic; HTTPS does that. For browsers and scraping tools, HTTP is the simpler default; pick SOCKS5 when an app only supports it or the traffic is not web traffic.

What each one does

An HTTP proxy speaks the web’s own protocol. For a plain http:// page it receives your request, fetches the page and passes it back, so it can read and even change what goes through. For an https:// page your software asks the proxy to open a tunnel to the site (the CONNECT method) and then talks to the site directly through it; the proxy sees which site and port you connect to, but the page itself stays encrypted between you and the site. Once open, the tunnel carries any TCP connection, so it can serve non-web software too, though many proxies only allow web ports such as 443, and it cannot carry UDP (Wikipedia: HTTP tunnel).

A SOCKS5 proxy works one level lower. It does not care what protocol runs inside the connection: it opens the connection you ask for and relays the bytes both ways. That is why it can carry email, file transfer, SSH and other non-web traffic, and why it supports UDP as well as TCP. It can also take a site name rather than an address and resolve it at the proxy, so your own network never sees the lookup. Relaying is not privacy: SOCKS has no encryption of its own, so anything not already encrypted, such as a plain http:// page, can be read on its way through (Wikipedia: SOCKS). SOCKS5 added the user name and password login that proxy providers use; the older SOCKS4 has no password login and no UDP, which is why providers sell SOCKS5.

What changes in practice

Speed is not a reason to choose: both forward the same bytes over the same network, and the provider’s pool and your target decide how fast pages come back.

Does SOCKS5 cost more?

Rarely. The box above counts how many providers whose pages list protocols include SOCKS5; on those pages, HTTP and SOCKS5 usually come on the same plan, through the same gateway on a different port or with a different scheme. A few providers sell a separate SOCKS5 product, so check the plan rather than the provider. When a provider’s page names no protocol, ask before buying if SOCKS5 matters to you; the comparison never assumes it.

To see only plans whose pages state SOCKS5, switch on “SOCKS5” under “Refine” on the residential comparison, or start from the cheapest SOCKS5 proxies.

Which to pick

• Scraping, price checks, browser automation: HTTP. Every tool supports it, and it is how providers document their examples.
• An app with only a SOCKS setting, or non-web traffic: SOCKS5.
• You want site lookups to happen at the proxy: SOCKS5 with remote name resolution (in curl, the socks5h:// scheme).

The protocol does not change what the proxy costs or which address you get; the proxy type does. Static vs rotating proxies and ISP vs residential proxies cover that choice.
