Proxy setup guides

Step-by-step setups for the tools our customers run: scrapers, headless browsers, SEO software and AI agents. Each guide shows where the gateway goes, how many threads to use and what to do when something fails.

Proxy basics

How rotating, backconnect and unlimited-bandwidth proxies work, in plain words.

Fix proxy errors

What common proxy errors mean and how to clear them fast.

Here’s why.429 Too Many RequestsRate limits through proxies: Retry-After, backoff and spreading load.

How Storm Proxies connect, in 30 seconds

You get fixed gateway IP:PORTs in the member area. Your tool connects to the gateway, and the gateway sends each request out through an IP from our pool. You authorize your own IP once, so there are no passwords to paste into rotating or residential setups. Every plan has unlimited bandwidth: you pay for threads, ports or proxies, never for gigabytes.

Rotating proxies from $14/mo · Residential proxies from $19/mo · Dedicated proxies 5 for $10/mo

Unlimited bandwidth. One flat monthly price.
