Real browser tabs via extension relay beats managing headless Docker farms.

Strengths
  • Extension-based nodes eliminate chromedriver version matching and complex Docker overhead.
  • Relay architecture allows controlling browsers on remote machines securely without VPN.
  • Network interception and site-scoped commands enable complex agent workflows easily.
Weaknesses
  • Requires manual Chrome extension installation on every single target machine.
  • Less scalable than cloud grids for massive parallel execution tasks.
