You connect your site (Webflow, WordPress, Shopify, custom code via Git) once. Agents propose a change as a diff or a preview, you approve it (or let trusted agents ship automatically), and the change goes live with a one-click rollback safety net.
Every change runs through a sandboxed preview, a Lighthouse + visual regression check, and a typed schema validator before going live. If a metric drops, Halcyon auto-reverts within minutes.
Yes — upload a brand book, paste a few of your favorite pages, or just describe your style. Every agent is constrained by your guardrails.
Webflow, WordPress, Shopify, Framer, Wix, Ghost, and any static or custom site connected via Git or our REST API.
Never. Your content stays in your tenant. Agents run on isolated, instruction-tuned models with strict retention windows.
Connect your website, hire your first agent, and ship a real change before your coffee gets cold.
