General
Section titled “General”What is editor-web?
Section titled “What is editor-web?”An AI-powered editor for building, previewing, and shipping website changes by describing them in plain language. It includes a multi-pane workspace with live browser preview, task planning, sub-agents, testing, and more. See What is Coframe Agent?.
Do I need to know how to code?
Section titled “Do I need to know how to code?”No. You describe changes in everyday language and the editor builds them. If you do read code, you can review what it produces in the Files panel.
Does the preview affect my live site?
Section titled “Does the preview affect my live site?”No. The preview is an isolated Chromium browser. Nothing reaches real visitors until you publish.
How is this different from v0 or Lovable?
Section titled “How is this different from v0 or Lovable?”Those tools focus on building new apps from scratch. Coframe Agent works on your existing website — editing your production codebase, creating variants for A/B testing, and optimizing what’s already live. See the full comparison.
The workspace
Section titled “The workspace”What panels are available?
Section titled “What panels are available?”Eight panels: Chat, Tasks, Requirements, Preview, Files, Sub-agents, Skills, and Tests. You can arrange, resize, and toggle them. See the workspace overview.
Can I rearrange the layout?
Section titled “Can I rearrange the layout?”Yes. Drag panels to rearrange them, split horizontally or vertically, or collapse panels you don’t need. The layout persists within a session.
Working in a session
Section titled “Working in a session”My change isn’t what I expected
Section titled “My change isn’t what I expected”Refine it with a follow-up instruction — see Iterating on a change. You can also click on elements in the preview and annotate what’s wrong.
The preview looks broken or empty
Section titled “The preview looks broken or empty”Give larger changes a few seconds to apply. The preview uses a real Chromium browser that needs time to render. If it still looks wrong, describe what you see in chat and the agent will adjust.
Can I undo something?
Section titled “Can I undo something?”Yes. Ask the agent to undo the last change or go back to an earlier point in the session.
What are sub-agents?
Section titled “What are sub-agents?”When the agent gets a complex request, it can delegate parts to sub-agents that work in parallel. You can watch each sub-agent’s progress in the Sub-agents panel.
How do skills work?
Section titled “How do skills work?”Skills are reusable packages of knowledge and workflows. Install them from a repo, URL, or local path, and the agent uses them automatically when relevant. You can toggle skills on/off per session.
Can I run tests?
Section titled “Can I run tests?”Yes. The Tests panel runs vitest suites in the sandbox. Results stream in real time and are mapped to your requirements.
Publishing
Section titled “Publishing”How do I make a change live?
Section titled “How do I make a change live?”Publish it from your session once it looks right in the preview. See Publishing a change.
Can I keep editing after publishing?
Section titled “Can I keep editing after publishing?”Yes — continue in the same session, or start a new one for unrelated work.
For developers
Section titled “For developers”Can I embed editor-web in my app?
Section titled “Can I embed editor-web in my app?”Yes. There are multiple integration options including iframe embed, REST SDK, WebSocket streaming, annotation surface, and a session client for building completely custom UIs.
Can I use the API without the UI?
Section titled “Can I use the API without the UI?”Yes. The REST SDK lets you start sessions and collect results from your backend without any UI.
