What is Testing Agent?
Automated full-site or feature-focused visual checks run from the workspace, optionally driving a real browser. Catches regressions AI iteration introduces faster than manual clicking.

Staging Environment
A non-production copy for testing changes before release. Staging must be authenticated or noindexed so preview URLs never compete with the live site.
Live Preview
A running browser view of the generated site updating as code changes. Immediate feedback is the core loop of AI building: prompt, see, refine.
Accessibility Checker
Automated WCAG scanning (contrast, labels, alt text, empty controls) as an audit baseline. Machine checks catch the common failures; manual review covers what tools cannot detect.
One-Click Deployment
Publishing a site to production hosting without manual configuration. BYOB deploys to an edge network with rollback to known commits when a release misbehaves.
Custom Domain
Your own address (you.com) instead of a builder subdomain, with automatic SSL. The trust baseline for anything commercial: subdomains convert worse and rank no better.
Visual Editing
Clicking page elements in a live preview and asking the AI to refine text, spacing, or layout. It keeps non-developers in flow while the underlying code stays standard and editable.
