Three steps to zero bot traffic
No complex setup, no infrastructure changes. Integrate in an afternoon.
Add the snippet
One JavaScript tag. Works on any framework or plain HTML. No build step, no SDK to maintain.
Run in the background
Our WASM module silently collects browser signals and solves a cryptographic proof-of-work. No user interaction required.
Verify server-side
Call our REST API with the returned token. We give you a pass/fail signal you can act on immediately.
Built for regulated industries
yaan processes signals ephemerally in-browser. We don't store personal data, we don't use cookies, and we don't send data to third-party servers. Swiss-hosted, GDPR-native from day one.
