Proxy pricing terms

Each of these is explained on its own page with a real plan from our dataset where the term changes the price, named and sourced.

Minimum checkout cost

The smallest amount you can actually pay a provider to start using its proxies. It is not the advertised rate per GB multiplied by the traffic you want. Advertised rates usually belong to a volume tier, and you cannot buy a large tier's rate at a small tier's volume.

Effective cost per used GB

Checkout cost divided by the traffic you will actually use, rather than by the traffic the plan includes. If a plan sells 100 GB and you use 40, your effective cost is two and a half times the advertised rate.

Bandwidth expiry

How long unused traffic stays usable. Traffic that expires in 30 days is a cheaper product than traffic that never expires, and providers price it that way. Where the same plan is sold at several expiry windows, each one has its own price.

Rollover

Whether unused traffic carries into the next billing period. Rollover is the difference between paying for what you use and paying for what you forecast.

Bandwidth pooling

Whether one balance of traffic can be shared across sub-users, proxies or plans, or whether each is metered separately. Pooling decides whether you buy one large allowance or several small ones, and several small ones almost always cost more per GB.

Overage

What you pay per GB after the included traffic runs out. An overage rate well above the plan rate turns an under-sized plan into an expensive one.

Concurrency limit

How many requests or sessions a plan lets you run at once. A plan you cannot run your thread count on is not cheap for your job, it is unusable for it. This is where inexpensive plans are usually made inexpensive.

Thread limit

A per-plan cap on parallel connections, stated separately from concurrency by some providers. Worth checking against the scraper you actually run before comparing prices at all.

Rotating proxy

An address that changes on every request or at a fixed interval. Suited to work where each request should look unrelated to the last.

Sticky session

An address held for a set period, from a minute to several hours depending on the provider. Necessary for anything that carries a login or a cart across requests, and the maximum duration varies enough between providers to decide the choice.

ISP or static residential proxy

A residentially registered address hosted in a datacenter. It combines datacenter speed with residential registration, and it is usually sold per IP per month rather than per GB, which makes it hard to compare against per-GB plans without doing the arithmetic properly.

Geo premium

An extra charge for targeting a specific country, state, city or network. Some providers include country targeting and charge for city or ASN targeting, so the advertised rate is only the rate for untargeted traffic.

Unlimited bandwidth plan

A plan sold without a traffic meter. The cost is moved somewhere else, usually into a concurrency cap, a speed cap, or a per-port fee. Unlimited describes the meter, never the capacity.

These have a page but no entry in the list above, so they are named here rather than left reachable only from the site index.

• Commitment and prepayment terms
• Fair use ceilings
• Port based versus endpoint based access
• Promotional pricing
• Tax exclusive pricing
• Trial pricing
• Volume discounts

These are accurate but do not yet have a page of their own. They are the queue for the next writing pass, and saying so is more useful than a stub that pretends otherwise.

Success rate

The share of requests that return a usable response. It is measured by whoever ran the test, on their targets, at their moment, so it belongs next to the tester's name and date rather than inside a price. We run no tests of our own.

Cost per successful GB

Effective cost per used GB divided by the success rate. It is the only figure that lets a cheap, unreliable plan be compared honestly against an expensive, reliable one, and it is only as good as the success rate it is given.

Not published

The provider does not list a public price for this plan. It is a fact about the provider, not a gap in the data, so the row stays visible with a link to the provider's own page instead of an estimate.
