Puter is an open-source “internet operating system” that runs entirely in the browser, providing users with a full cloud-based desktop environment. It is designed to act as a personal cloud computer where users can store files, run applications, and access tools from anywhere without needing traditional local installation or server setup.

The platform combines cloud storage, file management, web apps, and AI capabilities into a single unified system. Users can interact with a desktop-like interface directly in the browser, where they can manage files, install or run apps, and use built-in services such as AI chat, image generation, and automation tools.

A core idea behind Puter is removing backend complexity for developers. It provides serverless primitives such as authentication, storage, databases, and AI APIs that can be used directly from frontend code without managing infrastructure. This allows developers to build full-stack applications entirely in the browser while delegating backend responsibilities to Puter’s cloud layer.

Puter also functions as a privacy-focused alternative to traditional cloud services, emphasizing user control over data and eliminating the need for personal server management. It is designed to be extensible, enabling developers to build and publish web apps, tools, and games directly inside the ecosystem.

The system is positioned as both a personal cloud operating system for users and a development platform for building serverless web applications.

Key features include:

• Full browser-based desktop operating system (cloud computer)
• Built-in file storage, apps, and application management
• Serverless backend services (auth, storage, database, hosting)
• Integrated AI tools (chat, image generation, and more)
• Open-source and self-hostable architecture
• Developer SDK for building frontend-only full-stack apps

Common use cases include:

• Using a cloud desktop from any device
• Building serverless web applications
• Storing and managing files in a personal cloud
• Deploying AI-powered apps without backend infrastructure
• Running lightweight web tools entirely in the browser

Puter is developed as an open-source project and positioned as an "Internet OS" that merges cloud computing, developer infrastructure, and personal computing into one browser-based environment.
