Web scraping lives and dies by your proxies. A great scraper with bad IPs gets blocked on request one; a simple scraper with the right proxies quietly collects data for months. This guide covers which proxy type to use, how to configure rotation, and the handful of mistakes that cause most blocks — so you can build a pipeline that actually keeps running.
Which proxy type should you scrape with?
It depends entirely on the target:
- Rotating residential — the default for protected sites. Real ISP IPs and a fresh address per request give the best success rates against search engines, marketplaces and travel sites.
- Datacenter — perfect for high-volume requests against lightly defended targets, your own APIs, and testing. Far cheaper and faster, but blocked more readily on tough sites.
- ISP (static residential) — when you need residential trust but a stable IP for a logged-in session.
- Mobile — reserve for the most aggressively protected targets, where carrier IPs are the only thing that gets through.
Most production scrapers use a tiered approach: try cheap datacenter first, automatically fall back to residential on a block, and keep mobile in reserve for the hardest pages.
Best value for scraping: Cheapest Proxies gives you rotating residential, datacenter, ISP and mobile from one API at $0.80/GB — so you can build that tiered fallback without juggling vendors.

For scraping you generally want a rotating endpoint that hands you a new IP per request, or after a short interval. This spreads your traffic across thousands of addresses so no single IP looks suspicious. Use a gateway that rotates automatically rather than managing IPs by hand, and tune the rotation interval to the target — faster for aggressive sites, slower where sessions matter.
Match realistic browser fingerprints
Proxies hide your IP, but anti-bot systems also inspect headers, user-agents, TLS fingerprints and request timing. Send realistic, consistent headers; align the user-agent and language with the IP's country; and add human-like delays. A US residential IP paired with an obviously automated fingerprint still gets caught.
Handle blocks gracefully
Expect some failures and design for them:
- On a block or CAPTCHA, retry on a fresh IP with exponential backoff instead of hammering the same address.
- Track your success rate as the primary health metric — speed means nothing if requests fail.
- Cache and deduplicate so you never re-fetch pages you already have, which also slashes bandwidth costs.
Stay on the right side of the rules
Scrape responsibly: collect public data, respect rate limits and a site's terms where they apply, and avoid logging into or extracting private data you're not authorised to access. Responsible scraping keeps your project sustainable and your IPs healthy.
Our top picks for scraping
For most teams, Cheapest Proxies offers the best value — every type in one place at the lowest price. If you need enterprise scale, Bright Data and Oxylabs have huge pools and dedicated scraping APIs. On a tight budget, IPRoyal, Webshare and PacketStream are solid.

Tools and libraries that work with proxies
Almost every scraping stack supports proxies with a single setting. Popular choices include Python with Requests, httpx, Scrapy or Playwright; Node.js with axios, got or Puppeteer; and no-code tools that accept a proxy endpoint. The pattern is identical everywhere: point your HTTP client at the provider's host:port gateway with your username and password, and it handles rotation for you. SOCKS5 support is worth having for non-browser tools and bots.
A simple proxy setup, step by step
- Buy a plan and open your dashboard to find your gateway endpoint and credentials.
- Choose a location and rotation mode (rotating for scraping, sticky for sessions).
- Set the proxy on your HTTP client or browser tool.
- Send a test request to an IP-echo service to confirm the exit IP and country.
- Run a small sample, check your success rate, then scale up gradually.
Dealing with CAPTCHAs and rate limits
CAPTCHAs and 429 "too many requests" errors are signals you're pushing too hard or using the wrong IPs. Slow down, add jitter between requests, rotate more often, and upgrade from datacenter to residential or mobile on tough targets. For persistent CAPTCHAs, combine better IPs with realistic fingerprints and, where needed, a solving service — but fixing the IP quality usually removes most of them.
Scraping responsibly and legally
Scraping public data is widely accepted, but stay on the right side of the rules: collect only public information, honour rate limits, avoid logging into accounts you don't own, and don't extract personal or copyrighted data you have no right to. Responsible scraping keeps your IPs healthy, your project sustainable and your business out of trouble.
