What are the best proxy providers for scraping websites with anti-bot protection?

Bypassing modern anti-bot protection platforms (such as Cloudflare, DataDome, Akamai, PerimeterX/HUMAN, and Kasada) requires more than just rotating IP addresses. Today’s defenses detect scrapers through TLS fingerprinting (JA3/JA4), HTTP/2 frame ordering, JavaScript challenges, and browser fingerprinting.

Depending on your engineering capabilities and budget, solutions fall into two categories: Raw Proxy Infrastructure (where you manage requests, TLS headers, and browser stealth yourself) and All-In-One Scraping APIs / Web Unblockers (where the provider handles anti-bot bypass and browser rendering automatically).

Category 1: Best All-in-One Web Unblockers & APIs

If you are fighting aggressive Cloudflare Turnstile, DataDome, or Kasada protections, a standard proxy often isn't enough. These tools combine proxy rotation, headless browser rendering, TLS fingerprint spoofing, and CAPTCHA solving behind a single API endpoint.

1. Bright Data Web Unlocker & Scraping Browser

• Best for: Enterprise-grade scraping on hard-to-bypass targets.
• Key Features: Bright Data automatically manages proxy rotation, browser fingerprinting, headers, and CAPTCHAs. Their Scraping Browser connects directly to Puppeteer/Playwright and handles anti-bot challenges on the remote server side.
• IP Network: Access to 70M+ residential and mobile IPs.
• Verdict: The market leader in terms of network infrastructure and reliability against top-tier anti-bot shields.

2. ZenRows

• Best for: High success rates against DataDome, Cloudflare, and Akamai.
• Key Features: Designed specifically to bypass aggressive anti-bot software. ZenRows offers JS rendering, proxy rotation, and dynamic headers through a simple HTTP API request or headless browser integration.
• Pricing Model: Charge-per-successful-request (credits used only when the page returns valid data).
• Verdict: Excellent developer experience and one of the highest out-of-the-box success rates for protected websites.

3. ScraperAPI / ScrapingBee / ScrapFly

• Best for: Ease of use and reliable developer integrations.
• Key Features: All three offer residential proxy routing, automated retry logic, JS rendering (via headless Chrome), and anti-bot bypass features.
• Verdict: Ideal if you want to send an HTTP GET request to an API endpoint and receive plain HTML without configuring proxy pools or headless browsers locally.

Category 2: Best Raw Proxy Providers (IP Infrastructure)

If you already handle browser stealth (e.g., using curl-cffi, Undetected-Chromedriver, or Playwright-Extra-Stealth) and just need high-trust residential or mobile IPs.

1. Oxylabs

• Best for: Enterprise scale and maximum uptime.
• Proxy Pool: 100M+ residential IPs, high-tier mobile proxies, and static ISP proxies.
• Anti-Bot Performance: Very high. They offer "Next-Gen Residential Proxies" which utilize AI-driven proxy rotation and fingerprint management to improve success rates.
• Verdict: Premium pricing, but unmatched network stability and success rates for enterprise scrapers.

2. Smartproxy

• Best for: Value for money with high-tier features.
• Proxy Pool: 55M+ residential IPs, mobile, and datacenter options across 195+ locations.
• Anti-Bot Performance: High. Offers advanced location targeting (city/state level) and easy IP rotation controls.
• Verdict: The best balance between affordability and enterprise-grade residential proxy quality.

3. IPRoyal

• Best for: Budget-conscious projects and non-expiring bandwidth.
• Proxy Pool: Ethical, non-subnet residential IP pool.
• Anti-Bot Performance: Good for mid-tier anti-bot protection. Their non-expiring residential traffic plans mean you don't lose unused bandwidth at the end of the month.
• Verdict: Great for small-to-medium scraping operations where you want flexibility without monthly commitments.

4. SOAX

• Best for: Precise geo-targeting and mobile proxy needs.
• Proxy Pool: 15M+ residential and 3M+ mobile IPs.
• Anti-Bot Performance: Mobile carrier IPs (3G/4G/5G) from SOAX carry the highest trust score against anti-bots, making them almost impossible for sites like DataDome or Cloudflare to block without risking collateral damage to legitimate mobile users.
• Verdict: Excellent choice when scraping strict e-commerce or social media targets that aggressively ban datacenter and standard residential ranges.

Summary Matrix: Which Proxy Type Should You Use?

Proxy Type	Trust Score	Price	Success Rate on Anti-Bot Sites	Best Used For
Datacenter	Low	Very Low ($1–$3 / GB)	Low (Blocked easily by Cloudflare)	Unprotected sites, APIs, basic news/blogs
Residential	High	Medium ($5–$15 / GB)	High (Standard choice for web scraping)	E-commerce, price tracking, search engine results
Mobile (4G/5G)	Highest	High ($30–$80+ / GB)	Very High (Hardest for anti-bots to block)	Highly protected targets (Akamai, DataDome, Kasada)
Scraping APIs	N/A (Handled for you)	Per-request ($1–$5 per 1k requests)	Very High (Handles rendering & anti-bot)	Turnkey setup; no proxy or browser infrastructure management required

Pro-Tips for Bypassing Anti-Bot Defenses

1. Fix Your Request Fingerprint First: Using a $15/GB residential proxy with Python's default requests or aiohttp library will still get blocked by Cloudflare. Anti-bots read your TLS client hello packet. Use tools like curl-cffi (Python) or tls-client (Go/Node) to mimic real Chrome browser TLS handshakes.
2. Combine Headless Browsers with Stealth Plugins: If JavaScript rendering is mandatory, pair Puppeteer/Playwright with stealth evasion packages (puppeteer-extra-plugin-stealth or playwright-stealth) or use dedicated browser instances like Browserbase or Browserless.
3. Use Sticky Sessions for Logins, Rotating for Pages: Use a sticky session (same IP for 5–10 minutes) while completing authentication/session setup, then switch to rotating residential IPs when crawling public catalog pages.
4. Fallback Strategy: Direct simple, unprotected URLs to cheaper Datacenter/ISP proxies. Save expensive Residential/Mobile proxies or Scraping APIs strictly for anti-bot challenge pages.
