BrowserBase and Ceki both give AI agents browser access, but through fundamentally different architectures. BrowserBase runs Chrome instances in the cloud — you get a browser API backed by containers in data centers. Ceki connects you to real Chrome sessions running on real people's computers.
Architecture difference
BrowserBase: Your agent → BrowserBase API → Cloud Chrome instance (datacenter). Ceki: Your agent → Ceki API → Real Chrome on a real person's computer (residential). This architectural difference affects everything.
Fingerprints: BrowserBase's cloud instances have generated fingerprints. They look like Chrome, but the hardware identifiers (WebGL renderer, Canvas hash) don't match any real consumer hardware. Advanced anti-bot systems can detect this. Ceki's sessions have genuine hardware fingerprints from real consumer devices.
IP addresses: BrowserBase uses datacenter IPs (primarily US-based). Ceki uses residential IPs from 50+ countries. Target websites increasingly distinguish between datacenter and residential traffic.
Cost structure: BrowserBase charges $99/month base fee + per-minute usage. Ceki charges per-minute only, no base fee. For light usage (under 2,000 minutes/month), Ceki is significantly cheaper.
When BrowserBase wins
You need SOC2 compliance documentation. You need guaranteed uptime SLAs for enterprise deployments. You need consistent, predictable performance (not dependent on host availability). You're scraping sites with minimal anti-bot protection. You need to run sessions in parallel at massive scale (100+ concurrent sessions).
When Ceki wins
Target sites have aggressive anti-bot protection (Cloudflare, Akamai). You need residential IPs from specific countries. You need authentic hardware fingerprints. CAPTCHA solving is required (human-in-the-loop). Per-minute billing without monthly commitment fits your budget. MCP integration is preferred.
