Never used a proxy? Start here.
About a 15 minute read. No jargon dropped on you without a plain-English picture first. By the end you can pick for yourself, without asking anyone.
You do not have to read in order. If pricing is your only question, jump straight to "How you get billed".
A proxy is the courier you send shopping
You do not walk into the shop yourself. You send a courier: the courier goes in, pays, and brings the goods back. All the shop ever sees is the courier, not you, not your home address.
The site sees your home internet address directly. Open one page a thousand times and it knows it is the same person, then usually locks you out.
The site sees the courier's address. You can ask for a different courier every time, or the same one throughout when you need it. That really is the whole trick.
What actually happens, in four steps
All of it finishes in seconds and you never see steps 2 to 4. Still worth knowing, so nothing surprises you when something breaks.
In your browser, app, or script settings you fill in the proxy address and port number. Two fields, nothing to install.
It confirms your username and password are right and your quota is not empty, then passes the request on to the target site.
The site handles the request as usual and sends its answer back. The visitor it logs is the proxy address, not yours.
The answer lands in your tool, and the data that travelled both ways is deducted from your quota. That is one full round trip.
Why people bother with proxies at all
The pattern is always the same: one internet address can only look like one person. The moment you need to look like many people, or like someone in another country, you need a proxy.
Watching marketplace prices
Want a competitor's price every hour? Hitting one page thousands of times from one address gets you locked out. Through a proxy each check looks like a different shopper.
Running several social accounts
Ten accounts from one internet address look like one person gaming the system. Give each account its own address and the problem goes away.
Checking your ads actually show
An ad you paid to show in the US may not show there. Borrow an address in that country and you can see it yourself instead of trusting a report.
Testing your own site from abroad
Your shop may look different, or crawl, when opened from another country. This is the cheapest way to check without asking a friend over there.
Playing with multiple characters
Some games count how many accounts sign in from one address. Separate addresses let each character stand on its own.
Collecting data at scale
Pulling thousands of pages from one address always hits the brakes. Spread across many addresses the job keeps running without swamping anyone's site.
What is the difference between a proxy and a VPN?
Short version: a VPN is one big hose that pulls the whole house through it, a proxy is a courier you send on one specific errand. Both are legitimate, they just do different jobs.
| Proxy | VPN | |
|---|---|---|
| What goes through it | Only the app you set up. Your browser goes through it, everything else stays on your normal connection. | Everything leaving the device, no exceptions, including apps sitting idle. |
| Different setting per job? | Yes. One tab on a US address, another on a Japanese one, at the same minute. | No. One device, one setting. Switch country and everything moves with it. |
| How many addresses you get | Many, and they can change on every single request if you want. | Usually one, changing only when you switch server yourself. |
| How it is billed | Per GB of data that actually moves. Not used, not charged. | A monthly subscription, charged every month even if you never open it. |
| Best suited to | Work: collecting data, multiple accounts, checking things from other countries. | Personal privacy: protecting all your traffic on cafe wifi. |
Honestly: a normal VPN fits that better and costs less. Per-GB proxies only pay off for repetitive work, many accounts, or when you need many addresses at once.
The five types we sell, and how they differ
The difference is not speed, it is who owns the address. That is what makes the prices so far apart, and it is also what decides whether you get turned away.
From real people's home internet, so it looks like a neighbour casually browsing.
Still real home connections, but filtered more tightly and shared by fewer users, so it gets refused less often.
Also home connections, but filtered and shared by fewer users, so you rarely inherit someone else's mess.
From servers in a data centre, not homes. Fast and cheap, but easier to spot.
From mobile carrier networks, exactly like the phone using data in your pocket.
| Pool | Where the address comes from | Sticky & rotating | Price for 1 GB | Cheapest per GB |
|---|---|---|---|---|
| Residential | From real people's home internet, so it looks like a neighbour casually browsing. | Rotating & sticky | Rp 14.100 | Rp 12.240 |
| Residential Plus | Still real home connections, but filtered more tightly and shared by fewer users, so it gets refused less often. | Rotating & sticky | Rp 18.100 | Rp 17.100 |
| Residential Elite | Also home connections, but filtered and shared by fewer users, so you rarely inherit someone else's mess. | Rotating & sticky | Rp 42.300 | Rp 36.720 |
| Datacenter | From servers in a data centre, not homes. Fast and cheap, but easier to spot. | Rotating & sticky | Rp 7.100 | Rp 6.120 |
| Mobile 4G | From mobile carrier networks, exactly like the phone using data in your pocket. | Rotating & sticky | Rp 28.200 | Rp 24.480 |
The cheapest per-GB rate applies to the largest bundle. The less you buy, the more each GB costs. Sticky session: the same IP is kept for several minutes, then it changes automatically. On Residential Plus: 5, 10, 30 or 60 minutes, picked in the console. Those minutes are the longest a session can last, not a guarantee: it can end sooner.
On the largest bundle, Residential Elite costs 6x what Datacenter costs, Mobile 4G 4x, and Residential 2x. If your target does not fight back, that money is simply wasted. Start cheap and move up only when you actually get refused.
When we measured it ourselves, there were addresses to use in 225 countries, but the spread is uneven: the United States runs deepest, while Indonesia only ranks 15th and Singapore 38th. The count moves every day, so we do not print it. If your job demands lots of Indonesian addresses, you should know that before paying, not after.
See each pool's coverageSo which one do I pick?
Answer these three honestly and the answer falls out. There is no wrong pick, only picks that are more expensive than you need.
Take 1 GB of Datacenter for Rp 7.100 and try it for a day. If it flows, that is your answer. If you keep getting refused, step up to Residential. This beats guessing.
Rotating IP vs sticky IP
These are not two products. Same pool, same price, the only difference is the port number you type. One number, and the behaviour flips completely.
Every request leaves from a different address. Perfect for bulk collection, because no single address ever looks busy.
Each port in 10000–29999 holds one address until its time runs out. Required when the job logs in, fills a cart, or anything with a session.
You log in through the rotating port. Page one arrives from address A, page two from address B. To the site, that account teleported in two seconds. Result: forced re-login, a verification challenge, or the account flagged as suspicious.
Those are ceilings, not promises. A session left idle can drop sooner, same as anywhere else.
HTTP, HTTPS, SOCKS5: which one?
These are just the language your tool uses to talk to the proxy. All three work on every pool we sell.
The default for web pages. If in doubt, pick this.
Same as HTTP, for pages with the padlock. Your tool usually picks it for you.
More flexible, handles non-web traffic too. Use it when an app asks for it.
Listed in the specs of Residential, Residential Elite, Datacenter and Mobile 4G: HTTP, HTTPS, SOCKS5, UDP. UDP is for non-web traffic — games, for instance. On Residential Plus UDP is not tested yet.
How you get billed, and why we chose it
The market has two habits: pay per GB of data moved, or rent an address by the month. We use the first, and here is why.
You buy a number of GB and only the data that truly travels is deducted. Not used today means not charged today. For a beginner this is the fairest, because your first month is mostly idle.
You rent a set of addresses with unlimited data. Sounds great, but it bills every month even when your tool sits idle, and locks you to the same addresses. We do not sell this model.
Written in all 5 pool specs: Quota never expires. Buy today, use it in six months, the amount is untouched.
Want an address from a specific country? No surcharge. Elsewhere this is a classic hidden fee.
Pin down to a state, a city or a specific network number and your quota is deducted 2x the data that actually moves. Buy 100 GB and it runs out at 50 GB. The one pool exempt from that is Residential Elite. On Residential Plus this rule is not measured yet, so ask us before using those filters there.
Do not just compare brochure per-GB figures. What matters is the cost per SUCCESSFUL request. A cheap pool refused seven times out of ten can cost more than a pricey pool that almost always gets through, because refused requests still burn quota.
See the full price ladderHow much is 1 GB, really?
A GB figure means nothing until you turn it into "how many pages". These are rough numbers, but enough to stop the worrying.
| What you open | Size of one | How many fit in 1 GB |
|---|---|---|
| Light text page (API results, plain pages) | 16 to 50 KB | 21,000 to 66,000 |
| An ordinary web page without heavy images | 50 to 200 KB | 5,000 to 21,000 |
| A heavy page, full of images and scripts | 1 to 4 MB | 260 to 1,000 |
| Opened in a full browser (a bot that really renders) | 2 to 8 MB | 130 to 510 |
1 GB on Datacenter costs Rp 7.100, on Residential it is Rp 14.100. For ordinary web pages that already buys thousands of them. There is no free quota here, but that first GB really is cheap enough for a first experiment.
Across our whole system 1 GB means 1024 MB, not 1000. The table is computed from that, then rounded for readability. Treat it as an estimate, not a promise.
Five ways to save quota that actually move the needle
The most common beginner fear: "this will be gone in a day". Fair enough, and here is how to stop that.
Turn images off when you do not need them
Images are the fattest part of a page. If you only want a price or some text, switch them off and usage can drop several times over.
Skip the full browser when you can
A bot that truly renders a page pulls every image, font, and script. If the data can be fetched directly, fetch it directly.
Test small before running big
Run 20 requests first, see the quota used, then multiply by a thousand. This is what stops end-of-month shocks.
Pick a pool that rarely gets refused
Refused requests still burn quota. A cheap pool that gets refused often can end up costing more overall.
Give each proxy account its own GB cap
Each proxy account can be capped separately. If your new script misbehaves, only that account's allowance dies, not everything.
Your first steps, the shortest version
Nothing to install. Just two fields to fill in inside a tool you already have.
What you need first
That is genuinely it. If your tool asks for a proxy type, choose HTTP. If it wants SOCKS5, that works too.
Same as a car: it can take a child to school or drive away from a crime. The tool is neutral, the driver is accountable. We do not read your traffic, but there are clear lines.
Attacking or flooding other people's sites, spreading malware, fraud, harvesting people's personal data, and anything against Indonesian law. Caught means the account is shut down, with no refund.
Collecting data that is genuinely public, checking your own ads and site rendering, managing accounts that are actually yours, and testing your own systems.
Glossary, one sentence per word
These words had to appear somewhere on this page. Tap any of them for the meaning.
IP
Your device's internet address, like a postal address. Sites log it every time you visit.
Pool
A bag of addresses you can borrow from. You do not pick individually, you draw from the pool.
Session
One run of visits a site treats as "the same person". A login is a session.
Rotating
The address changes on every request. Here that is port 823.
Sticky
The address holds for a set time, on ports 10000–29999. Sticky session: the same IP is kept for several minutes, then it changes automatically.
Thread
How many requests run at once. Here that is up to 5,000 concurrent connections per proxy account.
Gateway
One front door for Residential, Residential Elite, Datacenter and Mobile 4G: proxy.growtechcentral.com. Only the port and your login decide the pool and session type. Residential Plus has its own address and ports, shown in the console after you buy.
Quota
The data allowance you bought, counted in GB. It shrinks by whatever travels through the proxy, both ways.
Whitelist
A way in without typing a password: you register your own server address, and the proxy only serves that address.
The misunderstandings we meet most
Eight things newcomers nearly always ask, answered straight, including the ones you may not like.
I heard proxies are for illegal things, true?
No. It is an ordinary work tool, like a car or a kitchen knife. Companies use them to check competitor prices, monitor their own ads, and test their sites from abroad. Wrongdoing comes from the act, not the tool.
Why not just use free proxies? There are lists everywhere.
Because you do not know who runs it. Free proxies often skip encryption, can read what you send including passwords, and some have injected malware into the pages you open. If you are not paying, you are usually the product.
A proxy makes me completely anonymous, right?
No. A proxy only hides your internet address from the target site. If you still log in with the same account, or your browser has a distinctive fingerprint, the site can still recognise you. It is one layer, not an invisibility cloak.
Does my quota expire if I skip a month?
It does not. Retail quota has no expiry date: buy now, use it half a year later, the amount is unchanged. Only the reseller GB pools carry an expiry, and that is stated plainly on their own page.
Quota was charged for a failed request, is that a rip-off?
It looks that way, but the data really moved: your request went out, a reply came back, it just happened to be a refusal. We count data in motion. That is why cost per successful request matters more than headline per-GB rates. If the failure is proven to be on our side, contact support — our Refund Policy promises a replacement for a defect proven on our side.
Can one proxy account only run on one computer?
It can run on many machines and many jobs at once, up to 5,000 concurrent connections per account. Only the volume of data counts, not how many devices are plugged in.
What if the proxy address gets blocked?
You did not buy one address, you bought access to a pool. If one address is blocked, the next request leaves from another. If the whole pool is blocked, that is a sign to move to a cleaner pool rather than wait for a fix.
The priciest one must be the best, surely?
Priciest means hardest to refuse, not fastest. For relaxed targets, the data centre pool is both quicker AND cheaper. Paying a premium for an easy target is waste, not investment.
The four sensible pages to read next
The fastest way to understand: try it
Your first purchase can be a single GB at Rp 7.100, so you can prove whether your target accepts or refuses without a real outlay. The quota never expires, so buying just enough costs you nothing.
