An online proxy is a server that relays your web requests so the destination site sees the proxy's IP address instead of yours. You'll meet two main kinds: a browser-based web proxy you paste a URL into, and a hosted proxy server or residential network you configure for anything automated.
Key takeaways
- A browser-based online proxy needs no install, but it usually handles only page requests. It won't route apps, downloads, WebSockets or most streaming traffic.
- Free web proxies are the riskiest category in the market. To rewrite a page, they often terminate HTTPS, which means the operator can read your login credentials and session cookies.
- Residential proxy pricing in 2026 runs from about $1 per GB at the budget end to roughly $12 per GB at low volume with the enterprise incumbents.
- A proxy covers one browser or one app; a VPN encrypts the whole device. That difference decides most buying decisions.
- Headline rates hide commitments. IPRoyal's advertised $1.75/GB needs a 10 TB commitment; the 1 GB tier is $7.00/GB.
Here's the fast version of which type fits what.
| Type | What it is | Per-request IP control | Encrypts traffic | Best for |
|---|---|---|---|---|
| Browser web proxy | URL box on a website | No, one shared IP | No | Opening a single blocked public page |
| Browser extension proxy | Add-on that routes browser traffic | Sometimes | No | Quick IP switching while browsing |
| Hosted proxy server | HTTP or SOCKS5 endpoint you configure | Yes | No, tunnel only | Scraping, automation, QA testing |
| Residential network | Rotating real-device IPs | Yes | No | Scraping, ad verification, geo-testing |
| VPN | OS-level tunnel | No, rotates at connect | Yes | Whole-device privacy |
If you only need one page from another country, a browser web proxy is enough. Anything automated wants a hosted proxy server or a residential network.
What is an online proxy?
An online proxy is any proxy service you reach over the internet rather than running on your own machine: a web proxy page, a browser extension, or a hosted proxy server that forwards your requests from a different IP address and hands the response back to you.
The word "online" here isn't decoration. It separates remote services from the older setup of running Squid or similar software on your own hardware. That self-hosted route still exists, but it doesn't change your public IP, so it doesn't solve the problem most people are searching for.
There are two directions a proxy can face. A forward proxy sits in front of the client and hides the client from the server, which is what an online proxy means. A reverse proxy sits in front of the server and hides the server from clients, which is what CDNs do and is not what you're shopping for.
Note: "Online proxy" searches mix together people trying to unblock a page for five minutes and people running crawlers across millions of requests. Those two groups need completely different products, and the free tools built for the first group will fail badly at the second.
How does a browser-based web proxy work?
A browser-based web proxy works by taking a URL you submit, fetching that page from its own servers, and returning the result to you through the proxy's domain. Your browser never opens a connection to the target site, so the site only ever sees the proxy's IP.
The mechanics matter more than the description. When you paste a URL into a web proxy, the request goes to the proxy server, which resolves the domain and pulls the page. To keep you inside the proxy, it rewrites internal links so they point back through its own address. That rewriting is where most of the trouble lives.
Modern pages are mostly JavaScript. Guarded content still loads with fetch calls, WebSocket connections and server-side API endpoints, and a URL-box proxy typically doesn't rewrite any of those. You get the shell of the page and a broken experience.
HTTPS raises the harder problem. To rewrite a page served over HTTPS, the proxy has to terminate the TLS connection, decrypt the content, and re-encrypt it to you. It can do that because your browser talks to the proxy, not the site. The trade is that the proxy operator sees everything in plaintext, including anything you type into a form.
Extensions work slightly differently. A proxy extension, the kind you'd associate with "proxy browser" or "browser proxy" searches, usually sets the browser's own proxy settings for you rather than rewriting pages. Traffic passes through the proxy as a raw tunnel, so TLS stays end to end. That's a meaningful security difference, though the traffic still leaves from the proxy's IP and the operator can still log which domains you visit.
Are free online proxies safe?
For reading a public page you don't log into, a free proxy is low risk. For anything with a password, it usually isn't safe at all, because the same TLS termination that lets a web proxy rewrite pages also lets the operator read your credentials in plaintext.
The business model explains the rest. Free proxies have server bills and no revenue from you, so the money comes from somewhere: injected advertising, session-cookie harvesting, bundled scripts, or reselling your traffic to someone who wants to route through your connection. Any of those can turn a five-minute convenience into a compromised account.
Warning: If a free web proxy asks you to accept a certificate warning before it will load a site, stop. That warning means your browser is no longer verifying the site's identity, and everything you send afterward passes through the proxy unencrypted.
There's a supply-side problem too. Residential proxy networks source IPs from real devices, and the cheapest supply comes from apps and browser extensions that hide proxy functionality inside their terms. In early 2026 Google dismantled a major hijacked-device proxy network, and in March of that year French law enforcement took down a service operating roughly 35,000 proxies. The free and near-free end of the market is where that traffic tends to end up.
Paid proxies aren't automatically ethical either, but they have a clearer chain of consent: the operator pays for bandwidth from people who agreed to supply it. That's the practical reason most professional users avoid the free tier rather than a moral one.
Online proxy vs VPN: which do you need?
A proxy covers one application or one browser profile; a VPN covers the entire device and encrypts traffic at the operating system level. If you need one site to see a different IP for one task, use a proxy. If you want everything your machine does to leave through another country, use a VPN.
The difference that most people miss is rotation. Proxies can change IP per request, which is why scraping tools depend on them. A VPN gives you one IP for the whole session and reconnects are obvious and slow. Conversely, a VPN encrypts traffic between you and the exit node, while a proxy usually doesn't encrypt anything on its own, it just forwards.
| Requirement | Proxy | VPN |
|---|---|---|
| Scope | One app or browser profile | Whole device |
| IP rotation per request | Yes | No |
| Encrypts your traffic | No, unless the protocol does | Yes |
| Makes you look like a normal home user | Only with residential IPs | Rarely |
| Typical entry cost | $1 to $12 per GB | Flat monthly fee |
You can run both at once. A common setup is a VPN on the device for general privacy plus a proxy configured in one browser profile for the work that needs specific IPs.
What are online proxies used for?
Four jobs cover most online proxy use: collecting public web data at scale, checking how a site looks from another country, verifying ads and prices, and keeping separate accounts from bleeding into each other.
Scraping is the biggest. Sites rate-limit by IP, so a crawler running from one address gets blocked quickly. Rotating residential proxies spread requests across many addresses that look like ordinary home connections, which raises success rates. Datacenter proxies are far cheaper and faster but easier to fingerprint, so they suit targets with looser defenses.
Geo-testing and ad verification come next. If you run an ad campaign in five countries, you need to see the page as a user in each one, including localized pricing, currency and creative. Country-level targeting matters here, and on some providers it costs extra. DataImpulse, for instance, includes country-level geo-targeting across all 195 regions it covers at no additional fee.
Multi-account work is the third, and it's the one to be careful with. Platforms treat proxy use as a signal, and a proxy won't save an account that violates their terms. Buy residential IPs if you need them, but read the platform's rules first.
How much do online proxies cost?
Residential proxies run from about $1 per GB at the budget end to roughly $12 per GB at entry volume with enterprise providers. Datacenter IPs are a different market entirely and often cost well under a dollar per IP.
| Provider | Entry residential rate | Notes |
|---|---|---|
| DataImpulse | $1/GB pay-as-you-go | No subscription, traffic never expires, country targeting across 195 regions included |
| MarsProxies | $1.65/GB | Datacenter from $0.99/IP |
| Scrapeless | $1.80/GB | 90M+ IPs across 195+ countries |
| Webshare | $3.50/GB | Standing 50% discount; $2.00/GB at 250GB, $1.75/GB at 500GB; datacenter around $0.23 to $0.30/IP |
| Decodo (formerly Smartproxy) | $3.75/GB on the 3GB plan | $3.50/GB at 10GB, $2.75/GB at 100GB, $4.00/GB pay-as-you-go, from $2.00/GB at enterprise volume |
| IPRoyal | $7.00/GB at the 1GB tier | Headline $1.75/GB requires a 10TB commitment; ISP proxies $2.00 to $2.70/IP |
| Oxylabs | Around $12/GB at low volume | Roughly $7/GB at enterprise scale; one estimator lists a $6 to $49 per GB range |
| Storm Proxies | Around $14/GB | Froxy at $2.69/GB sits far below it |
Compare the tier you'd actually buy, not the marketing floor. IPRoyal's advertised $1.75/GB rate requires a 10TB bulk commitment, so a small project pays $7.00/GB. That gap is normal across the industry.
Billing model matters as much as rate. Pay-as-you-go with non-expiring traffic suits intermittent work; subscription tiers are cheaper per gigabyte but punish you if you don't use the allowance. Dedicated IPs bill differently again: Bright Data's dedicated IPs start at $22 per month for 10 proxies and scale to $1,300 per month for 1,000, with shared dedicated IPs starting at $14 per month.
The competitive picture shifted in 2026. Smartproxy rebranded to Decodo, and in a March 2026 head-to-head comparison Decodo beat Bright Data and holds an Editors' Choice award, with both services rated four stars. Meanwhile budget entrants keep pushing the floor down while Oxylabs and Bright Data hold roughly $6 to $12 per GB at entry volumes.
Pro tip: If your usage is bursty, price the pay-as-you-go tier even when the subscription looks cheaper. Unused gigabytes are the most common way people overspend on proxies.
How do you set up an online proxy?
Setup takes about five minutes for a browser extension and longer for a scripted crawler, because the crawler needs authentication and error handling built in.
- Choose the proxy type first. Datacenter for cheap, tolerant targets; residential for sites that block datacenter ranges; ISP or static residential when you need one sticky IP.
- Buy the smallest tier that covers a test run. A gigabyte of residential traffic is plenty to measure success rates before committing.
- In Chrome or Firefox, set the proxy under network settings using the host, port, username and password your provider gives you. Most providers also publish a browser extension, which is easier but ties the proxy to that browser only.
- For scripts, pass the proxy to your HTTP client. Rotating endpoints usually accept session flags that hold one IP for a defined period.
- Test before scaling. Check that the exit IP matches the country you asked for and that your target site returns the content you expect.
Note: If you're on Bright Data, the old SSL certificates on ports 22225 and 33335 expired on September 25, 2026 and can't be renewed. Customers need to migrate to port 44445 with the new root certificate, or connections will fail.
Limitations
An online proxy won't encrypt your traffic, won't hide you from a site that fingerprints browser behavior, and won't make a blocked account work again. It changes the IP a destination sees. That's the whole feature.
It also won't help if the site blocks by fingerprint rather than IP. Modern anti-bot systems read canvas hashes, fonts, timing and TLS signatures. A residential IP from the wrong browser stack still gets flagged, which is why serious scraping stacks pair proxies with browser automation that mimics real clients.
If your goal is general privacy from your internet provider, a VPN is the better tool and probably cheaper. If your goal is hiding from a state-level adversary, neither a proxy nor a commercial VPN is sufficient. And if you're scraping a site that prohibits it in its terms, no proxy changes that analysis.
Frequently asked questions
Do online proxies hide your IP address?
Yes, from the websites you reach through them, because those sites see the proxy's IP as the source of the request. They don't hide your IP from the proxy operator, from your internet provider, or from anyone monitoring the network between you. If you also need the connection itself hidden, you need encryption on top.
What's the difference between HTTP and SOCKS5 proxies?
HTTP proxies understand web requests and can modify headers, which is useful for filtering and caching but limits them to HTTP traffic. SOCKS5 proxies pass any TCP traffic without interpreting it, so they work for games, torrents and non-web protocols. For plain browsing the two behave similarly; for anything unusual, SOCKS5 is the more flexible choice.
Can websites detect that you're using a proxy?
Often, yes. Sites check whether the IP belongs to a datacenter range, whether it appears on published proxy lists, and whether the browser fingerprint matches the claimed location. Residential and mobile IPs are much harder to flag than datacenter ones, which is the main reason they cost more per gigabyte.
Do online proxies work on mobile browsers?
Web proxy pages work in any mobile browser because they're just websites. System-wide proxy settings are more limited on iOS and Android, and browser extensions are largely unavailable in mobile browsers, so mobile proxy use usually means a paid proxy plus a dedicated browser app or a device-level VPN-style client.
Choosing the right proxy for your job
Match the tool to the task before you compare prices. One blocked page wants a paid extension proxy or a VPN; recurring data collection wants a residential network billed per gigabyte; ad verification wants country targeting included rather than sold as an add-on.
Start with a one-gigabyte pay-as-you-go tier, measure your success rate against the specific target site, and only then commit to volume. The cheapest headline rate is meaningless if half your requests get blocked.
