# Tor vs Proxy: What Is the Difference and Which to Choose?

A researcher wants the forum she studies not to recognize her; the same day, an e-commerce team writes a script that checks hourly how its product pages look from Germany. Both start from "I need to hide my IP address" and both run into the same two words: Tor and proxy. Yet the two tools do not answer the same question. One hides who you are, the other sends your traffic out from an address you choose.

This post explains how the Tor network works, why Tor Browser is not the same thing as the network, and how a proxy sits in between. Then come one comparison table, what an exit relay can see, why websites show CAPTCHAs to Tor traffic, and which tool fits which job. Facts about Tor were checked against the Tor Project's own support documentation on 7 October 2026.

> **Note: Short answer**

> Tor passes your traffic through at least three volunteer-run relays with layered encryption, so no single relay knows both who you are and where you are going. That makes it the right tool for anonymity and source protection, but it is slow, its exit addresses sit on a public list that websites use for CAPTCHAs and blocks, and it carries no UDP. A proxy is a single intermediary run by a provider you know: you choose the exit country, city and IP type, it is built for speed and automation, and it promises no anonymity. To protect your identity, use Tor; to do a job from a specific address at scale, use a proxy.

## What is Tor and how does it work?

Tor is a network of relays run by volunteers around the world, and the software that connects to it. Whoever watches your connection should not see which sites you visit, and the sites should not learn where you are. Both are developed by the Tor Project, a non-profit.

The "onion" in the name describes the encryption. Before opening a connection, your computer picks three relays and wraps the data in three separate layers; each relay can remove only its own. The Tor Project's support page sums up the difference from a simple proxy: with a typical proxy provider everyone enters and leaves through the same server, and the provider knows both who you are and what you browse; Tor passes your traffic through at least three different servers with a separate layer of encryption for each relay ([How is Tor different from other proxies?](https://support.torproject.org/about/#how-is-tor-different-from-other-proxies)).

A request takes this path:

1. **Entry (guard) relay.** Your computer connects directly to this relay. It sees your real IP address, but the data is still wrapped in two more layers, so it cannot tell where you are going. The client picks a few relays at random for this first hop and keeps them for a long time, which lowers the odds that someone adding malicious relays to the network lands on your first hop.
2. **Middle relay.** It receives the data from the guard, removes one more layer and forwards it to the exit relay. It knows neither you nor the destination.
3. **Exit relay.** It removes the last layer and sends the request to the website from its own IP address. The site sees only this relay's address; the relay knows the destination but not who asked.
4. **Circuit rotation.** The three-relay path is called a circuit. Tor reuses a working circuit for new connections for about ten minutes, then builds a new one; a failing circuit is replaced at once. An open long-lived connection stays on its circuit, because moving a stream between circuits would give someone watching part of the network repeated chances to match you to your destination.

The price of this design is speed. Traffic is encrypted three times, crosses volunteer servers in three different countries, and those servers share their capacity among everyone using them.

## Are Tor Browser and the Tor network the same thing?

No. The Tor network is the relays; Tor Browser is a Firefox-based browser prepared for using it. It pins many settings, from window size to fonts, so that all its users look alike and a site cannot recognize you by browser fingerprint either.

The important limit is this: Tor Browser routes only its own traffic over Tor. The Tor Project's support page states it plainly: any other application on your system, including other browsers, is not routed over the Tor network and is not protected; each needs to be configured separately ([Does Tor Browser protect other applications?](https://support.torproject.org/tbb/tbb-13/)). A desktop app running in the background keeps connecting from your real address.

Two buttons in the browser are also often confused. "New Identity" closes all tabs and windows, clears cookies and history, and uses new circuits for all connections. "New Tor Circuit for this Site" only reloads the active tab over a new circuit; it is for an exit relay that cannot reach the site, and it clears nothing.

## How does a proxy work?

A proxy is a single intermediary server between you and the website. Your browser or your code sends the request to the proxy, which forwards it from its own IP address and returns the response. The site sees the proxy's address, not yours. The difference from Tor is structural: there is one intermediary, and whoever runs it knows where your traffic comes from and where it goes. Trust in a proxy therefore rests on the provider, not the protocol: a company you have a contract with and whose logging policy you have read.

The same structure gives you what Tor does not: control. You choose the country, city and carrier line you exit from, keep one IP for a session or change it on every request, and authenticate with a username and password so the access is yours alone. It is configured in a line of code and scales to thousands of concurrent requests.

There are two common protocols. An HTTP proxy is built for web traffic and tunnels HTTPS connections with the `CONNECT` method. SOCKS5 works at a lower level and carries a connection without looking at its content; [RFC 1928](https://www.rfc-editor.org/rfc/rfc1928), from March 1996, defines three commands: `CONNECT` for a TCP connection, `BIND` for an inbound connection and `UDP ASSOCIATE` for UDP datagrams. The same document says the authentication method (none, or username/password) is negotiated at the start of the connection and that the protocol itself provides no encryption. That is why a [SOCKS5 Proxy](https://proxynet.io/socks5-proxy) is the choice for game clients and other UDP applications.

A site judges a proxy by the network its address belongs to. **Datacenter** IPs are registered to hosting facilities; fast and cheap, but sites know they are not home users. **Residential** IPs belong to real home connections and look like an ordinary visitor. **ISP** (static residential) IPs are registered to an internet provider but hosted in a datacenter, combining the residential look with a fixed address. Tor offers no such choice: the exit relay's IP is whatever it is.

## Key differences between Tor and a proxy

| Criterion | Tor | Proxy |
|---|---|---|
| Intermediaries | At least 3 volunteer relays | 1 server |
| Who runs it | Volunteers you do not know | A provider under contract |
| IP the site sees | A random exit relay | The IP you chose |
| Location choice | None | Country, city, carrier |
| Encryption | 3 layers inside the network | None of its own; HTTPS provides it |
| Speed | Low, variable | High, predictable |
| UDP | Not carried | Carried over SOCKS5 |
| Session stability | Circuit changes about every 10 min | Fixed, or new per request |
| Authentication | None | Username/password, IP allowlist |
| Exit IP reputation | On a public list, frequent CAPTCHAs | Clean, depending on type |
| Automation | Not designed for it | Easy to add to code and tools |
| Main purpose | Anonymity | Routing, scale, location |

## Can the exit node see my traffic?

Yes, the unencrypted part. Tor's three layers apply only inside the network; when the exit relay removes the last one, it holds the request itself. Over plain HTTP, the person running the exit relay can read the form you submit and the password in it. The Tor Project says so on its support page: information sent over plain HTTP can be intercepted by exit relay operators; on HTTPS sites the traffic leaving the exit relay is encrypted and only the destination is visible.

The same rule applies to a proxy, where a single intermediary carries all of the traffic. The difference is who that intermediary is: with Tor, a volunteer you do not know; with a proxy, a provider under contract. In both cases HTTPS hides the content from the intermediary; neither tool replaces it.

Tor has one more limit. Someone who can watch both ends of the network can match the timing of traffic going in and coming out. The Tor Project calls this traffic correlation and writes that in practice it confirms a person already under suspicion rather than discovering new ones. Keeping the entry guards fixed for a long time is a defence against exactly this.

## Why do websites show CAPTCHAs to Tor traffic or block it?

Because the IP addresses of Tor exit relays are not secret. The Tor Project publishes the list itself: its page for site administrators, "I want to ban the Tor network", links to the current exit relay list and a DNS-based version of it. The page suggests narrower measures than an outright ban, but the list is there and every bot protection reads it.

Cloudflare has turned this into an explicit rule. In its WAF and IP access rules, Tor exit nodes are a special "country" code, `T1`; a site owner can allow it, block it or serve a managed challenge. Cloudflare's Privacy Pass documentation adds that visitors from shared networks, VPNs and Tor tend to have poorer IP reputations and may receive a challenge page before reaching the site. The company's [Onion Routing](https://developers.cloudflare.com/network/onion-routing/) feature instead serves the site directly inside the Tor network, so a Tor user never passes through an exit node and interactive challenges go only to bot traffic.

The mechanism is simple. Thousands of people use one exit relay at the same time; the Tor Project's own support page explains that Google treats a burst of queries from a single exit IP as crawling and slows that address down for a while. This is not a flaw in Tor but a consequence of the design: anonymity comes from sharing an address with others.

With a proxy the picture is reversed. A residential IP belongs to a real home connection and looks like an ordinary visitor from that city; it is on no public list. If you need to check regularly how a page looks from a given city, a [Residential Proxy](https://proxynet.io/residential-proxy) exists for exactly that. Which headers a proxy adds to a request, and so whether a site can tell you are using one, is covered in our post on [transparent, anonymous and elite proxies](/blog/anonymous-proxy-levels).

## Speed, UDP and automation: where are Tor's limits?

Tor transports only correctly formed TCP streams; UDP packets cannot be sent over Tor, so game traffic, most video calls and other UDP applications do not work over it. On the proxy side, SOCKS5's `UDP ASSOCIATE` command exists for exactly this; the details are in our post on [what a SOCKS5 proxy is](/blog/socks5-proxy-101).

The Tor Project is just as clear about torrents: it does not recommend using Tor with BitTorrent and explains [why that is not a good idea](https://blog.torproject.org/bittorrent-over-tor-isnt-good-idea/) in a separate post. Torrent clients often ignore proxy settings and connect directly, send your real IP to the tracker, and slow down a volunteer network for everyone else.

The same reasoning applies to high-volume automation. A scraping job sends hundreds of requests a minute, keeps one session for a long time and needs a specific exit country. On Tor the circuit changes every ten minutes, you cannot choose the country, the exit IP already runs into CAPTCHAs, and the load lands on a network that runs on donations and volunteer time. The tool built for that job is a proxy: you set the scale, you pay for it, and you work from an address you share with no one.

## Where does a VPN fit in?

A VPN carries all of your device's traffic through an encrypted tunnel to one company's server; in that respect it is closer to a proxy than to Tor, because there is again a single intermediary you know. It differs from Tor in that this intermediary sees everything, and from a proxy in that it works per device rather than per application and usually offers one country exit. To protect the whole device on cafe Wi-Fi, use a VPN; to send one application out from a specific address, use a proxy; to keep who you are from every intermediary, use Tor. The detailed comparison is in our post on [proxy vs VPN](/blog/proxy-vs-vpn).

## When Tor, when a proxy?

Tor is the choice when the thing to protect is your identity. The Tor Project lists its users as journalists, researchers, human rights activists, whistleblowers and survivors of abuse. A journalist's contact with a source must not reveal where it came from; a researcher must not be recognized by the group she studies. Speed comes second; the point is that no intermediary knows who you are.

A proxy is the choice when the job itself is the point. Price monitoring, ad verification, checking search results, testing a site from different cities, giving each account its own fixed address, playing a game with low latency: all of these need an address in a specific country or city, with predictable speed, authentication and automation. Your provider already knows who you are; what you hide is not your identity but the address the target site sees.

Recipes for chaining the two circulate from time to time; we do not give them. Decide which problem you are solving and pick the tool for that.

## Common mistakes

- **Assuming the whole device is protected while Tor Browser is open.** Only the browser's traffic goes through Tor; other applications exit from your real address.
- **Entering passwords on plain HTTP sites over Tor.** The exit relay can read unencrypted content. If the address bar shows no HTTPS, do not enter anything sensitive.
- **Logging in over Tor and expecting to stay anonymous.** Once you sign in, the site recognizes you by the account, not the IP. The same holds for a proxy.
- **Thinking a proxy makes you anonymous.** A proxy hides your IP from the target site, not from the provider. Trust in a proxy rests on the contract.
- **Using Tor for scraping or torrents.** The Tor Project does not recommend it; it is slow, runs into CAPTCHAs and wears down a volunteer network.
- **Relying on the exit relay's country.** Choosing a country is not part of Tor's design; if you need to exit from a specific country, use a proxy.

## Decision guide

| Your need | Recommendation |
|---|---|
| No intermediary should know who you are | Tor |
| Journalism, research, whistleblowing: source protection | Tor (with Tor Browser) |
| How a page looks from a specific city | Proxy (residential) |
| Price monitoring, ad verification, SERP checks | Proxy (rotating or residential) |
| A fixed, clean address for each account | Proxy (ISP) |
| Games or UDP-based applications | Proxy (SOCKS5) |
| Protecting the whole device on cafe Wi-Fi | VPN |
| Programmable IP management from code | Proxy |
| Torrents or high-volume scraping | Not Tor; a proxy |

## Frequently asked questions

### Is Tor a proxy?

Technically the Tor client opens a SOCKS interface on your computer and applications connect to it as if it were a proxy; but Tor itself is a network of three relays with separate encryption at every hop, not a single intermediary. With a proxy the provider knows both who you are and what you browse; in Tor no relay knows both.

### Is Tor safer than a proxy?

For anonymity, yes, because no intermediary sees both you and the destination. For the privacy of the content, both depend on HTTPS: over plain HTTP a Tor exit relay and a proxy server can both read it. With a proxy, security comes from the provider's identity and contract; with Tor, from the design itself.

### Why is Tor so slow?

Traffic is encrypted three times and passes through three volunteer servers in different countries that share their capacity among everyone using them. The Tor Project says the network is much faster than it used to be, but by design it is not expected to match a paid, single-hop proxy.

### Can a Tor exit node see my traffic?

It can see the unencrypted part. If you connect over HTTPS, the exit relay sees only which site you are visiting, not the content. Over plain HTTP it can read the form and the password you submit.

### Can websites tell that I am using Tor?

Yes. The Tor Project publishes the IP list of exit relays openly, and infrastructure such as Cloudflare marks Tor traffic as a separate "country" with the code `T1`. A site can block it, show a challenge page or accept it as it is.

### Can I use Tor for scraping?

You should not. The circuit changes every ten minutes, you cannot choose the exit country, exit IPs already run into CAPTCHAs, and the load falls on a network carried by volunteers. If you need authenticated, scalable requests from a specific location, the tool built for that is a proxy.

## Summary

Tor and proxies are mentioned in the same breath, but they answer different questions. Tor passes your traffic through at least three volunteer relays with layered encryption so that no intermediary can match you to your destination; the price is low speed, frequent CAPTCHAs because exit lists are public, no UDP and no choice of location. A proxy is a single intermediary from a provider you know; it is fast, you pick the country and city, it is authenticated and suits automation, but it promises no anonymity. To protect your identity, choose Tor; to do a job from a specific address at scale, choose a proxy. To pick the IP type that fits your work, see our [proxy solutions](/proxy).
