When you ask your agent to build a website, it packages the result as a .webapp artifact — a self-contained static site that LabFrame deploys to a public URL.

​
How it works

  1. You ask: “Build a course homepage for CSCI 564”
  2. The agent writes HTML, CSS, and JavaScript into the workspace
  3. The agent packages the output as csci-564.webapp
  4. You click the artifact in chat — LabFrame deploys it and opens it in a new tab
The deployed site is available at a URL like: 
https://csci-564.labframe.ai/
Anyone with the link can view the site. No LabFrame account required.

​
Opening a web app

There are three ways to open a deployed web app:
ActionWhere
Click the .webapp link in a chat messageChat
Single-click the .webapp file, then click Open AppWorkspace
Double-click the .webapp fileWorkspace
If the site hasn’t been deployed yet (or the content changed since the last deploy), LabFrame deploys it automatically before opening. You will see a brief loading page while this happens.

​
Workspace preview

Single-clicking a .webapp file in the workspace shows a card with:
  • The app’s title and description (from the manifest)
  • An Open App button to open the deployed site in a new tab
  • A Copy URL button to copy the public URL to your clipboard

​
Updating a web app

Send a follow-up message to change the site:
Add a dark mode toggle to the course homepage.
The agent edits the source files, repackages the .webapp, and the next time you open it, LabFrame deploys the updated version.

​
Slugs

Each web app gets a slug — the subdomain in the URL. The slug comes from the app’s manifest and is globally unique. If your preferred slug is already taken, LabFrame appends a suffix like -2 or -3.

​
What’s inside a .webapp

A .webapp file is a ZIP archive containing a manifest and a static bundle: 
csci-564.webapp
  webapp.json          # title, slug, description, entry point
  bundle/
    index.html         # required
    assets/...         # CSS, JS, images, fonts
Static content only — no server-side code.
