Independent letter grades for residential and datacenter proxy providers. We score coverage, reliability, IP sourcing, and cost, then explain each grade in plain terms for developers and data teams choosing a network they can trust.

Buying proxies is hard because every provider claims the biggest pool, the fastest speeds, and a perfect success rate, and none of it means anything until you point it at a site that fights back. Proxy Grader cuts through that. We test and read the residential and datacenter proxy market the way a data team actually uses it, then hand every provider a single letter grade you can act on. An A means we would route production traffic through it without a second thought. A C means look closer before you commit budget.

The grade is the whole point. Behind it we weigh the things that decide whether a scraping or data job succeeds: real pool size and geographic reach, how honestly the network is sourced, success rate on hard targets, rotation and session control, the quality of the dashboard and API, and what it all costs at scale. We favor providers that are clear about where their IPs come from and that hold up under real load, and we mark down the ones that lean on marketing numbers.

Every provider is reviewed by hand and we write our own summary instead of restating a pricing page. As new proxy networks earn attention, the strongest ones rise. Read the grade first, then the write-up, then go test it yourself.
