01Kernel-level buildPRODUCT

The fastest agent browser

A custom Chromium engine — not a JavaScript shim on top of vanilla Chrome.

  • Marketplaces such as Amazon, where fingerprint and IP are policed hard
  • SaaS platforms and internal enterprise systems
  • Social media, several accounts in parallel

02AXTree extractionPRODUCT

Same task, far fewer tokens

AXTree returns filtered page structure with DOM noise stripped; cross-origin iframe and Shadow DOM supported for precise extraction.

  • Cuts page context by ~85% on average
  • Reads cross-origin iframes and Shadow DOM alike
  • Shorter context means lower latency and steadier decisions

Unique fingerprint environment

Custom browser fingerprints plus on-the-fly IP switching keep multi-account work safe.

  • One fingerprint and exit IP per instance
  • Sessions stay isolated across concurrent accounts
  • Fingerprint templates can be cloned and rolled out in bulk

Seamless handoff on sensitive steps

  • Resumes from the exact breakpoint once verified
  • Handoff records stay on-device too
