Burrow is a comprehensive development environment that operates entirely within a browser tab. Designed for accessibility and portability, it allows developers to write code, manage files, and execute applications without the need for complex local configuration or heavy software installations. The platform focuses on providing a streamlined coding experience that mirrors a traditional workstation while maintaining the flexibility of a web-based interface.

Burrow functions by providing an integrated terminal, file management system, and live preview capabilities within a single interface. It handles file operations through a project tree structure, allowing users to navigate through repositories and edit code files directly in the browser. The environment is built to support modern JavaScript and TypeScript development, specifically leveraging the Bun runtime for fast execution and server management.

Some of the key features are:

• Integrated Terminal: Provides full command-line access directly in the browser to run scripts, install dependencies, and interact with the file system.
• Live Preview System: Automatically detects servers started within the terminal, such as Bun.serve(), and hosts them in an embedded preview window.
• File Management: Includes a project tree structure for efficient navigation, creation, and editing of project files.
• Privacy Focused: Operates locally within the browser tab and explicitly states that it does not transmit user data or code to remote servers.
• AI Integration: Features built-in AI capabilities to assist with code changes, diff generation, and development workflows.

To use the platform, users simply navigate to the Burrow interface, which initializes a virtual development session. Users can open files from the file tree, edit them using the built-in text editor, or perform actions directly through the terminal console. When running a development server, such as a web application or API, the platform detects the process and makes the application available through the integrated preview pane. This eliminates the friction of switching between multiple applications or managing complex network configurations.

Some common use cases include:

• Rapid Prototyping: Quickly spinning up a new web project or testing code snippets in a persistent, isolated browser-based environment.
• Remote Pair Programming: Sharing a complete development environment through a browser link for collaborative coding sessions.
• Educational Labs: Providing students or workshop participants with a pre-configured, zero-install environment for practicing programming exercises.
• Lightweight Development: Enabling coding tasks on low-power devices or public terminals where installing a full IDE is not possible or desirable.
