Residential vs datacenter proxies

Try datacenter first. It costs a fraction of residential, and if your target site accepts it you have just saved most of your budget. Move to residential only when you have measured datacenter failing.

Residential

Providers selling it: 18
Cheapest we hold: $3.88
Dearest we hold: $8.40

Datacenter

Providers selling it: 7
Cheapest we hold: $0.90
Dearest we hold: $0.90

When residential is the right call

Your target has a real anti-bot vendor in front of it. Datacenter address ranges are published, easy to enumerate, and blocked in bulk, a site that wants to stop automated traffic starts by refusing every datacenter ASN, which costs it almost no real users. Residential addresses cannot be filtered that way without blocking actual customers, so they survive where datacenter does not.

When datacenter is the right call

Nobody is trying to stop you. Internal APIs, your own infrastructure, partner endpoints, sites with no bot defence, and the large amount of ordinary scraping that simply works. Paying residential rates here is paying 10 to 50 times over for a property you are not using, and datacenter is faster, because the traffic goes through a server rather than someone's home broadband.

What the vendor blogs leave out

Every vendor blog on this query concludes 'it depends on your use case' and then recommends residential, because residential is the expensive product. The measurable version: run a hundred requests through datacenter against your actual target and count the failures. That number decides it, and it costs about a dollar to find out.

Questions

How much cheaper is datacenter?

Roughly 10 to 50 times, depending on the provider and the commitment. That spread is why testing datacenter first is worth the hour it takes, the saving compounds across every gigabyte you ever buy.

Can a site tell I am using a datacenter proxy?

Usually, yes, and trivially. Datacenter IP ranges are registered to hosting companies and published; checking an address against that list is a lookup, not an inference. A residential address belongs to a consumer ISP and looks like a customer.

Is datacenter faster?

Generally yes. The exit is a server on a good connection rather than a household device on domestic broadband, so latency is lower and more consistent.
