• Zero setup: no drivers, no browser downloads, works on any installed browser including mobile Safari on a real phone.
• Automatic waiting and stable selectors with very little configuration.
• Genuinely simple concurrency flag for parallel runs.

• The human fallback covers scenarios automation genuinely cannot reach.
• Anyone on the team can author a test.
• Results in minutes, integrated into the deployment pipeline.

• The proxy architecture occasionally breaks on apps with strict CSP, service workers or unusual auth flows.
• Smaller community and slower ecosystem growth than Playwright or Cypress.
• No component testing story.

• Human runs get expensive quickly at any real frequency.
• Human testers lack product context, so results need interpretation.
• Web only.

Small teams who want a working cross-browser suite with the least possible setup.

Teams that need broad release-gate coverage including flows nobody wants to automate.
