Bright Data (formerly Luminati) is the world's largest proxy network with 72M+ residential IPs. Ceki is a browser rental marketplace with real Chrome sessions. They solve overlapping but different problems.
Proxies vs. browsers
Bright Data primarily sells proxy access: route your HTTP requests through residential, datacenter, or mobile IPs. They also offer a "Scraping Browser" product — a cloud-hosted browser with proxy integration. Ceki provides real browser sessions: you control an actual Chrome window on a real person's computer. It's not a proxy — it's a full browser with genuine fingerprints, cookies, and hardware identity.
The distinction matters because: proxies change your IP but not your fingerprint. Bright Data's Scraping Browser uses cloud instances (datacenter hardware). Real browser sessions have both authentic IPs AND authentic fingerprints.
Complexity and pricing
Bright Data has a complex product lineup: Datacenter Proxies, Residential Proxies, ISP Proxies, Mobile Proxies, Scraping Browser, Web Unlocker, SERP API, Data Collector. Each has different pricing (per-GB, per-request, or subscription). Enterprise plans start at $500+/month. Residential proxies cost $8-15/GB.
Ceki has one product: real browser sessions, billed per minute. Search, rent, use, close. No proxy configuration, no product selection, no minimum spend.
When Bright Data is the better choice
You need massive scale (millions of requests/day). You need raw proxy access (HTTP/SOCKS) for custom tools. You need a proven enterprise solution with dedicated support. Your use case is primarily data collection without browser interaction.
When Ceki is better
You need actual browser interaction (click, type, fill forms). Anti-bot systems block even residential proxies. You need human help with CAPTCHAs. You want simple pricing without enterprise sales calls. You're building AI agent workflows with MCP.
