Proxy Setup Guides & API Tutorials

A proxy server is an intermediary between your device and the internet. It routes your traffic through a different IP address, masking your real location and identity. Businesses use proxies for web scraping, ad verification, market research, and managing multiple accounts without triggering platform security checks.

Residential proxies use real IP addresses assigned by internet service providers to home users — they look like ordinary visitors and are hard to detect. Datacenter proxies are hosted in cloud infrastructure, so they are faster and cheaper but easier for sites to flag. Most teams start with datacenter IPs for speed-sensitive work and upgrade to residential for scraping protected targets.

For protected targets (search engines, e-commerce, social platforms), residential or mobile proxies give the highest success rate. For simpler targets and high-throughput jobs, datacenter IPv6 proxies are faster and cheaper. Rotate IPs every request, respect rate limits, and pair the right proxy tier with your target's defenses.

Yes — proxies are legal in most jurisdictions when used for legitimate purposes like market research, brand protection, ad verification, and accessing publicly available information. You are responsible for following the terms of service of the sites you access and the laws of your country. ColdProxy does not permit use for fraud, illegal content, or abuse.

Static proxies keep the same IP for the life of the session — ideal for managing accounts, checkout flows, or anything that needs a consistent identity. Rotating proxies swap IP every request or on a schedule — ideal for large-scale scraping where each request should look like a new visitor.

ColdProxy does not have a traditional free trial. Instead, hourly plans start at a few dollars so you can test any proxy type against your own targets with minimal commitment. Weekly and monthly plans are refundable for verified technical issues on our side.
