What we think after testing Coronium
Auto-composed from our test rig data + structured profile · last refreshed Jun 1, 2026
Coronium is a residential and datacenter proxies provider operating from their USA headquarters (founded 2021). Cloud proxy infrastructure. In our directory, Coronium sits in the mid-tier — capable but not the standout choice for every workload.
On the infrastructure side, the network advertises 1M+ IPs, 80+ countries. Our nightly test rig recorded a 97.0% success rate, 1.1s average response time against the standard target panel (Google SERP, Amazon, Cloudflare-fronted retailers, social platforms). The single-product focus keeps the dashboard simple but limits flexibility for teams whose workloads change shape over time.
Pricing starts at $5.00/GB, which is mid-market. Volume buyers should expect to negotiate — every provider in this category quotes higher rates on the public site than what enterprises actually pay. Compliance documentation is thin on the public site — confirm in writing before any contract that requires SOC 2 or DPA assurances.

-
1
Open an account & verify your inbox

Pick a starter package

Set up either an IP-whitelist auth or username:password pair from the dashboard. Save the proxy hostname + port into your scraper or browser config.
-
4
Set up session stickiness
Decide between rotating-on-every-request (best for SERP scraping) or sticky sessions (best for account-based workflows).

Benchmark before committing
Run 100-500 test requests against your real target before paying for volume. Compare success rate to Coronium's claimed rate before committing to an annual plan.
