Bright Data Review: The Largest Proxy Network for Web Data Collection

TL;DR

Bright Data has built the largest proxy network in the industry (72M+ residential IPs) and offers robust infrastructure for web data collection. For teams that need to collect data at massive scale while avoiding IP-based blocking, Bright Data's network is the industry standard. However, proxies solve the IP detection problem — they don't solve authentication, session management, or workflow orchestration, which require a different layer.

What Bright Data does well

Bright Data's infrastructure is genuinely impressive:

• 72M+ residential IPs — the largest proxy network available, with coverage across virtually every geography
• Multiple proxy types — residential, datacenter, ISP, and mobile proxies for different use cases
• Web Unlocker — their smart proxy solution handles CAPTCHAs, fingerprinting, and retries automatically
• Scraping Browser — a hosted browser environment that routes through their proxy network
• Enterprise grade — SOC 2 compliant, used by major enterprises for legitimate data collection

For data collection at scale, Bright Data's infrastructure handles the hardest networking problems reliably.

The proxy layer vs. the workflow layer

Proxies address one specific problem: making requests appear to come from different IP addresses to avoid rate limiting and IP-based blocking. This is important but it's only one piece of reliable automation.

A complete workflow automation solution also needs:

• Authentication management — logging in, maintaining sessions, handling MFA and SSO
• Request sequencing — executing multi-step workflows in the correct order with state carried between steps
• Error recovery — retrying failed steps, re-authenticating when sessions expire, classifying errors
• Anti-bot evasion beyond IPs — TLS fingerprinting, behavioral patterns, and request timing

Bright Data handles the IP layer. Workflow API platforms like Zatanna handle the full stack — including IP management as one component of a broader reliability layer.

When to use Bright Data

Bright Data is the right tool when:

• You're building your own scraping infrastructure and need reliable proxy access
• IP-based blocking is your primary obstacle
• You need geographic diversity in your requests
• You're collecting public data at enterprise scale

When to use workflow APIs

Workflow APIs are better when:

• You need to execute complete workflows in authenticated systems
• You want the full automation stack managed (auth, proxies, sessions, retries) as a single service
• You'd rather call an API endpoint than build and maintain scraping infrastructure
• Your use case is workflow execution, not just data collection

The bottom line

Bright Data builds the best proxy infrastructure available. Zatanna builds workflow automation that happens to use proxy infrastructure as one component. They're complementary — in fact, workflow API platforms often use proxy networks like Bright Data underneath. The question is whether you want to build the automation stack yourself on top of proxies, or use a managed workflow API that handles everything.
