What is the “Why does my browser agent fail on the cookie banner every single time?” problem in 2026?

Computer Use, Operator, and Claude in Chrome trip on the same mundane web furniture: cookie banners, captchas, modal popups, hover menus. Reliability hovers below 50%.

Existing players in this space

  • Skyvern — Open source, still trips on banners
  • Browse AI — Templates, not general
  • Operator / Computer Use — General, low reliability

What existing players are missing

A "web furniture" pre-handler: detect and resolve banners, modals, captchas before the agent thinks. Plus a flake-replay dashboard that surfaces the top 10 failures across the user's workflows and patches them.
