The two workhorses of proxy work solve the same problem from opposite ends. Datacenter proxies optimize for speed and cost; residential proxies optimize for looking human. Picking wrong means either overpaying for traffic you didn't need to protect, or getting blocked on day one. Here's how to choose.
Datacenter proxies run on servers in data centers. Their IPs belong to hosting-provider ASNs — and anti-bot systems keep lists of those. Residential proxies route through IPs that ISPs assigned to real homes, so they carry ordinary-user reputation. Everything else (speed, price, block rate) flows from this one fact.
| Factor | Residential | Datacenter |
|---|---|---|
| Looks like | A real home user | A server |
| Block rate (hard targets) | Low | High |
| Speed | Fast (extra hop) | Fastest |
| Price | ~$2/GB | ~$0.80/GB |
| IP pool size | Millions, rotating | Smaller, fixed |
| Geo coverage | 190+ countries | Limited |
Use residential when the target fights back or personalizes by location: marketplaces, search engines, social platforms, ticketing, ad verification, multi-accounting. Use datacenter when the target is tolerant and you need throughput: internal tools, APIs you're allowed to hit, bulk fetches of unprotected pages.
Many teams use both — residential for the hard 20% of targets, datacenter for the easy 80%. A provider that meters both on one balance (Roam bills residential at $2/GB and datacenter at $0.80/GB from the same wallet) makes splitting traffic a one-line change.
Yes — for speed-critical, high-volume jobs against targets that don't block by ASN, datacenter proxies are faster and cheaper. The IP quality just has to matter less than throughput for your use case.
With a provider that offers both on one account, yes — usually it's a change to the username or endpoint. On Roam you add a datacenter marker to the username and traffic bills at the datacenter rate instead.
Per GB, datacenter (~$0.80) is cheaper than residential (~$2). But if datacenter gets you blocked and you have to retry or fail, residential can be cheaper per successful request. Match the network to the target.
