Steel.dev is an open-source cloud browser API — you can self-host it or use their managed service. Ceki is a peer-to-peer marketplace connecting you to real people's browsers. Both serve AI agents, but the trade-offs are different.
Cloud vs. peer-to-peer
Steel runs Chrome instances in Docker containers. You get fast, consistent, scalable browser access. But the instances run on cloud hardware with datacenter IPs and generated fingerprints. Ceki connects you to Chrome sessions on real consumer hardware. Startup may be slightly slower, but the session is indistinguishable from a real user because it IS a real user's browser.
Open-source advantage
Steel's biggest draw is open-source: you can self-host, customize, and audit the code. For teams that need full control over their browser infrastructure, this is compelling. Ceki is a managed marketplace — you trust the platform to handle session isolation and billing.
Fingerprint quality
Steel generates random fingerprints from cloud hardware (typically NVIDIA data center GPUs, not consumer GPUs). The WebGL renderer, Canvas hash, and AudioContext won't match any consumer device. Ceki's fingerprints are genuine because they come from consumer devices. An Intel UHD 630 fingerprint from a host's laptop is identical to any other Intel UHD 630 laptop — because it IS an Intel UHD 630 laptop.
CAPTCHA handling
Steel uses automated CAPTCHA solving (~70% success rate for reCAPTCHA). Ceki uses human-in-the-loop solving (the host solves it manually — near 100% success rate). For workflows where CAPTCHA failure means task failure, human solving is more reliable.
Pricing
Steel managed: $29-499/month + per-hour usage. Self-hosted: your infrastructure costs. Ceki: $0.02-$0.10/minute, no subscription.
