Boxy

Boxy was CodeSandbox’s built-in AI assistant for developers, designed to help you turn ideas into working code faster inside a cloud workspace.

Code understanding in project context

Boxy could read the current file and related modules to provide context-aware explanations. This was useful when working with unfamiliar repositories, legacy code, or complex architectures.

• Explain code snippets and project logic
• Highlight dependencies and potential issues

Generate and refactor code

You could ask Boxy to create new functions, components, or tests from a text prompt, or improve existing code without changing behavior.

• Generate features and components from descriptions
• Refactor for structure, readability, and maintainability
• Suggest optimizations while preserving functionality

CodeSandbox integration and status

Because it ran inside CodeSandbox, Boxy could take the project environment, dependencies, and settings into account while you worked.

• Note: Boxy was officially discontinued in July 2024. AI features in CodeSandbox are now available via Codeium.
