What is a Vibe?
Web apps that AI can build and operate
Last updated: March 2026
The platform
vibe-coded.ai is a hosting platform for web applications. You describe what you want, the Vibe Builder's AI agents build it, and the result is a live app with hosting, storage, and an API — no infrastructure to manage.
We call these apps vibes. Each vibe gets its own URL and storage. Full-stack vibes also get AI-callable tools via the Model Context Protocol (MCP), so AI assistants like Claude, Cursor, or any MCP client can interact with your app's data directly.
Three types of vibes
Vibes come in three flavors, depending on what you need:
| Type | What it includes | MCP tools |
|---|---|---|
| Static HTML | A single index.html file. Great for landing pages, one-pagers, and simple tools. |
No |
| Vue + Vite SPA | A full frontend with components, routing, and a build step. Uses Vue 3 and Vite. | No |
| Full-stack | Frontend + a backend with storage and API endpoints. Backend functions are automatically exposed as AI-callable MCP tools. | Yes |
Most vibes built by the Vibe Builder are full-stack, since they typically need to store and retrieve data.
URL structure
Every vibe gets a unique URL based on your username and the vibe's name:
https://{your-username}--{vibe-name}.vibe-coded.aiFor example, if your username is alice and you create a vibe called recipe-book, it lives at:
https://alice--recipe-book.vibe-coded.aiWhat you get out of the box
- Hosting — Your vibe is deployed to a global edge network. No servers to manage.
- Storage — Key-value storage included on all plans. A dedicated SQL database and file storage available on Pro.
- MCP tools — Full-stack vibes automatically expose backend functions as AI-callable tools, discoverable by any MCP-compatible client.
- OAuth 2.1 — Built-in authorization server so AI clients can securely access your vibe's tools.
- Access control — Share vibes with collaborators using role-based permissions.
