Proxy for Web Scraping
The foundation of uninterrupted, scalable data collection without blocks is the right proxy infrastructure. Crawl thousands of pages in parallel with our rotating residential pool.
Highlights for This Scenario
Why Is a Proxy Essential in Scraping?
Modern sites detect heavy requests from a single IP within seconds: rate limits kick in, CAPTCHA walls go up, and then the IP is blocked entirely. A proxy layer changes this equation — when your requests are spread across hundreds of different IPs, each address stays at a low pace the site treats as normal.
The proxy requirements of a successful scraping operation come down to three: IP diversity (pool size), IP quality (the residential/datacenter balance) and automatic rotation.
Which Proxy Type Should You Choose?
| Target Site Type | Recommended Proxy | Why |
|---|---|---|
| Aggressively protected (marketplaces, social networks) | Residential + rotation | Real user IPs get past the protections |
| Moderately protected (news, classified sites) | Rotating residential or mixed | Cost/success balance |
| Unprotected (open sources, APIs) | Datacenter | Highest speed, lowest cost |
| Large IPv6-capable targets | IPv6 | Huge volume at a tenth of the cost |
5 Basic Rules for Avoiding Bans
- Humanize your request pace: Send requests with random delays, not at fixed intervals.
- Set rotation up correctly: Use per-request rotation on listing pages and sticky sessions on flows that require a session.
- Keep your headers realistic: An up-to-date User-Agent, Accept-Language and consistent cookie handling.
- Measure failure: If your 403/429 rate is rising, slow the pace down or widen the IP pool.
- Respect robots.txt and legal limits: Sustainable scraping starts with respecting the target's rules.

Tool Integration
Scrapy, Playwright, Puppeteer, Selenium and every HTTP client work with a single gateway definition:
--proxy gw.freeproxy.tr:7777 --proxy-user username:password — one line on the code side; rotation, retries and IP health are managed on our side.

Frequently Asked Questions
01How much traffic (GB) do I need for scraping?
An average HTML page is 0.5-2 MB. If you fetch only HTML without downloading images, a 25 GB package covers roughly 25,000-50,000 pages.
02What should I do if I hit a CAPTCHA?
The CAPTCHA rate is directly related to IP quality and request pace. Moving to the residential pool and slowing the pace reduces it significantly; design your flow to retry for the remaining exceptions.
03How do you crawl JavaScript-heavy sites?
With headless browsers such as Playwright or Puppeteer. Both support the proxy parameter natively; in-page navigation works smoothly with a sticky session.
04Is web scraping legal?
Collecting publicly available data is legal in many countries; however, the target site's terms of use, copyright and personal data law must be observed. Seek legal advice in doubtful cases.
