# SOCKS5 vs HTTP proxy: how they differ and which to use URL: https://cloudj.net/blog/socks5-vs-http-proxy Published: 2026-11-11 ยท Updated: 2026-11-11 > SOCKS5 vs HTTP proxy explained: protocol layers, how HTTPS passes through CONNECT, DNS handling, app support, and a simple way to choose for each tool you use. When you order a proxy you usually have to pick a protocol, and the SOCKS5 vs HTTP proxy question comes up immediately. Both forward your traffic through another IP address, and for most web work both will do the job. The differences show up in the details: which layer the proxy works at, how HTTPS is handled, where DNS lookups happen, and which apps support which protocol. This article explains those details in plain terms and ends with a short rule for choosing. ## The short answer - Use **HTTP** when the client is a browser, a phone's Wi-Fi proxy setting, or an HTTP library, and you want the setup that works almost everywhere. - Use **SOCKS5** when the application supports it natively and is not purely web traffic, or when you want the proxy to resolve DNS names for you. - If you are unsure, start with HTTP. On Cloudj you can switch the protocol of an order in the console later, where the location supports it. ## How an HTTP proxy works An HTTP proxy speaks the same protocol as web servers. What happens depends on whether the destination is plain HTTP or HTTPS. ### Plain HTTP requests For an `http://` URL, the client sends the whole request to the proxy, including the full URL. The proxy reads it, makes the request to the destination on your behalf, and returns the response. Because the proxy sees the request, an HTTP proxy can in principle read headers, filter or cache. Very little traffic is plain HTTP today, so this case matters less than it used to. ### HTTPS through CONNECT For an `https://` URL, the client sends a `CONNECT` request naming the host and port, for example `CONNECT shop.example.com:443`. The proxy opens a TCP connection to that destination and then simply relays bytes in both directions. The TLS handshake happens between your client and the destination, so the content stays encrypted end to end. The proxy learns the destination host name and port, but not the pages, form data or cookies. This is why an HTTP proxy is fine for HTTPS sites: it becomes a tunnel as soon as `CONNECT` succeeds. ## How a SOCKS5 proxy works SOCKS5 sits one level lower. It does not understand HTTP at all. The client tells the proxy "connect me to this host and port", the proxy opens the connection, and from then on it relays the raw stream. Whatever runs inside (HTTPS, an email protocol, a game client's TCP connection) passes through unchanged. The SOCKS5 standard also defines a way to relay UDP, but support varies between providers and clients. Cloudj proxies do not offer UDP, so plan on TCP traffic only. SOCKS5 has its own username and password authentication. Cloudj proxies use username and password by default, or an IP whitelist of up to 20 addresses that replaces password access. ## SOCKS5 vs HTTP proxy side by side | | HTTP proxy | SOCKS5 proxy | |---|---|---| | Works at | Application layer, understands HTTP | Session layer, relays any TCP stream | | HTTPS sites | Through `CONNECT`, encrypted end to end | Relayed as a raw stream, encrypted end to end | | Non-web TCP apps | Only if the app can use `CONNECT` | Yes, if the app supports SOCKS5 | | UDP | No | Defined in the standard; not offered by Cloudj | | DNS lookup | Done by the proxy (it receives the host name) | Client's choice: local or at the proxy | | Phone Wi-Fi proxy settings | Supported on Android and iPhone | Not in the standard Wi-Fi settings | | Browser support for password login | Broad | Limited in several browsers | ## DNS: the detail people miss With an HTTP proxy, the client sends the host name to the proxy, and the proxy resolves it. Your local network never looks up the destination. With SOCKS5 the client decides. In `curl`, `socks5://` resolves the name on your machine and sends the IP to the proxy, while `socks5h://` sends the host name and lets the proxy resolve it: ```bash # DNS resolved locally curl -x socks5://USER:PASS@HOST:PORT https://ipinfo.io/ip # DNS resolved by the proxy curl -x socks5h://USER:PASS@HOST:PORT https://ipinfo.io/ip # HTTP proxy, DNS resolved by the proxy curl -x http://USER:PASS@HOST:PORT https://ipinfo.io/ip ``` Remote resolution matters when you want results that match the proxy's country, for example a site that answers with a different regional server depending on where the DNS query comes from. For more tests like these, see [testing a proxy with curl](https://cloudj.net/blog/test-proxy-curl). ## Which apps support which protocol ### Browsers Browsers handle HTTP proxies with username and password well. SOCKS5 is supported too, but several browsers do not offer a username and password prompt for SOCKS5. If you want SOCKS5 in a browser, pair it with the IP whitelist, or use HTTP. The [Chrome and Firefox proxy setup guide](https://cloudj.net/blog/setup-proxy-chrome-firefox) covers both. ### Phones The manual proxy field in Android and iPhone Wi-Fi settings is an HTTP proxy. For phones, HTTP is the straightforward choice; see [setting up a proxy on Android and iPhone](https://cloudj.net/blog/setup-proxy-android-iphone). ### Scripts and automation Most HTTP libraries accept an HTTP proxy out of the box. Python's `requests` needs an extra package for SOCKS support, as described in the [requests documentation](https://requests.readthedocs.io/en/latest/user/advanced/#socks). Playwright and Puppeteer accept both; the [Playwright and Puppeteer proxy guide](https://cloudj.net/blog/playwright-puppeteer-proxy) has examples, and [Python scraping with proxies](https://cloudj.net/blog/python-scraping-proxy) covers `requests` in more depth. ### Desktop tools and antidetect browsers Many messaging apps, download managers and antidetect browsers support both. Use whichever the tool documents best. [Antidetect browsers with proxies](https://cloudj.net/blog/antidetect-browser-proxy) covers profile-based setups. ## Security: what neither protocol does Neither protocol encrypts the connection between you and the proxy by itself. With HTTPS sites, your content is protected by TLS regardless of the proxy type. The proxy login, however, is sent to the proxy without encryption in both cases. That is one reason to rotate proxy passwords when people leave a team, which you can do from the Cloudj console, and to consider the IP whitelist when everyone works from a fixed office line. If you need an encrypted tunnel for all of a device's traffic, that is a VPN's job; see [proxy vs VPN](https://cloudj.net/blog/proxy-vs-vpn). ## Protocol is not the only choice The protocol decides how traffic reaches the proxy. Two other choices decide what the destination sees: the IP type and whether the IP is yours alone. Cloudj sells dedicated IPv4 proxies, which are static ISP IPs, in seven countries and static residential ISP proxies in the United States and Vietnam; [datacenter vs static ISP proxies](https://cloudj.net/blog/datacenter-vs-static-isp-proxy) compares the main IP types on the market. [Dedicated vs shared proxies](https://cloudj.net/blog/dedicated-vs-shared-proxy) and [static vs rotating proxies](https://cloudj.net/blog/static-vs-rotating-proxy) cover the rest, and the [dedicated proxy guide](https://cloudj.net/blog/dedicated-proxy-guide) ties it all together. ## FAQ ### Is SOCKS5 faster than HTTP? For HTTPS traffic both end up relaying an encrypted stream, so the protocol itself is rarely the deciding factor. The proxy's location and your application matter more. ### Is SOCKS5 more anonymous? Neither adds encryption. With HTTPS, the destination sees the proxy IP either way. An HTTP proxy used for plain HTTP can pass along headers your client adds, which is one more reason to use HTTPS. ### Can I change the protocol after ordering? Yes. In the Cloudj console you can switch an order between HTTP and SOCKS5 where the location supports it. Update the protocol in your apps afterwards. ### Which should I use for Telegram or other desktop apps? Use whatever the app supports; many desktop apps support SOCKS5 directly. ## Try both on one order Order a dedicated proxy in the [Cloudj console](https://app.cloudj.net), start with the protocol your main tool supports, and switch if a second tool needs the other one. Prices per IP are on the [proxy page](https://cloudj.net/proxy-ipv4).
