Crawl and index the web at scale
A crawler that runs from one IP gets exactly as far as that IP's rate limit allows. After a few thousand requests the responses turn into 429s, then captchas, then nothing at all.
Spreading the same crawl over a large pool of residential addresses removes that ceiling. Each request looks like an ordinary visitor from an ordinary connection, so the crawl keeps its pace instead of stalling on the third page of every site.
What gets in the way
Most sites count requests per address. One machine, one address, one small budget of requests per minute. The crawl is capped by the slowest site you touch.
Cloud IP ranges are published. Anti-bot vendors subscribe to them. A crawl from a cheap VPS gets flagged before the first page renders.
Search pages, prices and stock levels differ by country and city. Crawling from one location gives you one version of the web, not the version your users see.
How Rainproxy handles it
- Rotate on every request, or hold a sticky session for as long as a crawl of a single site needs.
- Target country, state, city or ASN so each page is fetched from where it actually matters.
- Pay for the bandwidth you use, or take an unlimited plan when the crawl runs around the clock.
- Concurrency is not capped, so parallel workers scale with your infrastructure, not with your plan.
110M+ IPs and per-request rotation, which is what a broad crawl needs most.

There is no concurrency cap on our plans. In practice the limit is your own workers and the politeness you want to show the target site.
Rotating for breadth-first crawling of many domains. Sticky when a site keeps state across pages, like a paginated search behind a session cookie.
HTML-only crawling is usually 50-200 KB per page. Blocking images and fonts at the client keeps the bill down considerably.
