VibesOS - a GUI for Claude Code that makes unhackable mini-apps

Instantly make your own small multi-user apps, without a backend. For apps made with Vibes, the front-end is the app.

What is Vibes?

Vibes is a vibe coding framework made for coding agents. It collapses application code and application state into a single HTML file that runs anywhere.

Why does this matter? AI doesn't make apps - it makes text. By embedding the database in JavaScript (via TinyBase), your coding agent can describe an entire app - including its persistence layer - in one shot. No server setup, no schema imports. Just a working app.

Your data lives locally in the browser, encrypted and portable. It syncs across users automatically. Share your creations with a simple link and friends can jump in immediately.

Installation

MacOS users can download the desktop app.

If you want to run it as a plugin, register the marketplace first:

/plugin marketplace add popmechanic/VibesOS

Then install the plugin:

/plugin install vibes@VibesOS

Restart Claude Code after installation.

Plugin Quick Start

After installation, open Claude Code and enter /launch, then choose the Editor option. Claude will then open a web GUI designed to help you produce secure, vibe coded apps.

It's still Claude Code under the hood, we just help you with a nice user interface. Use the GUI to turn your ideas into simple deployable multiplayer apps that don't require a server. (So you don't have to be a Linux genius to run a great app.)

Skills

Skills are model-invoked - Claude automatically uses them when your task matches the skill's purpose. Just describe what you want to build.

vibes

Generate a complete, working app from a prompt. Perfect when you have a clear idea and want to see it working quickly.

Creates a single HTML file with inline JavaScript, TinyBase for local-first reactive data, and Tailwind CSS styling. No build step - just open and run.

Example prompts:

• "Make a chore chart for my roommates"
• "Build a potluck sign-up for Friendsgiving"
• "Create a trivia game about reality TV"

Commands

Commands are user-invoked — run them explicitly when you want a specific skill.

Command	What it does
/vibes	Generate a React web app with TinyBase
/launch	Build and deploy a SaaS app end-to-end using Agent Teams

Why Vibes?

Every vibe-coded project starts in the vibe zone - the AI understands you, progress is fast, each change moves the app forward.

Then something small goes wrong. A fix that mostly works. An edge case layered on top. You correct it, then correct the correction, and suddenly progress slows to a crawl.

You've drifted out of the vibe zone.

Vibes OS keeps things simple enough that you stay in the vibe zone. Single-file apps. Local-first data. No server complexity. The AI can see and understand everything it needs to help you.

How Data Works

Vibes apps use TinyBase, a reactive data store for local-first apps:

• Offline-first: Apps work without internet, sync when connected
• Reactive: Automatic re-rendering when data changes via React hooks
• Shareable: Real-time sync across users via WebSocket relay
• Portable: Simple table/row data model, easy to export

The hidden settings menu (gear icon) lets you configure sync for collaboration.
