Sandbox

The sandbox is the Expert’s isolated cloud execution environment. Whenever you have a conversation with an Expert that requires code execution or file management, the platform automatically allocates a sandbox for you. You don’t need to install any software or configure any environment — everything works out of the box.

​

What Can the Sandbox Do

​

Pre-installed Environment

The sandbox image comes pre-installed with commonly used development tools and frameworks, ready for the Expert to use:

​

Sandbox Isolation

Each user-Expert combination has its own isolated sandbox environment:

• User isolation: Your sandbox is completely isolated from other users and invisible to them
• Expert isolation: Sandboxes for different Experts are also isolated — Expert A’s files won’t appear in Expert B
• Security boundary: Code execution within the sandbox is protected by resource limits and security policies

​

On-Demand Startup

The sandbox uses a lazy start strategy — resource-intensive services are only started when needed:

1. Text-only conversations: No sandbox is started, no execution environment resources consumed
2. Code execution needed: Sandbox starts automatically (typically ready within seconds)
3. Website preview needed: Development server starts on demand after the sandbox is running

This design ensures you only consume compute resources when truly needed — regular Q&A conversations incur no extra overhead.

​

File Persistence

The sandbox uses a persistent cloud file system (CFS) for file storage:

• Code, documents, images, and other files generated by the Expert are automatically saved
• Files are not lost when you close the browser
• When you reopen a conversation with the same Expert, your previous files are still there
• Multiple sessions with the same Expert share the same workspace file system

​

File Sync

During a conversation, files created or modified by the Expert are automatically synced to your file panel. In the file browser on the right side of the conversation interface, you can:

• Browse the file directory structure
• Open and read file contents
• Download files to your local machine

​

Website Preview

When the Expert builds a website, you can view it in real time in the preview panel on the right side of the conversation interface:

• Live refresh: After the Expert modifies code, the preview updates automatically
• Hot reload: Supports HMR (Hot Module Replacement) for instant changes
• Full-screen view: The preview panel can be expanded to full-screen mode

​

Storage Limits

Sandbox storage is limited by your subscription plan:

​

Sandbox and the Sites Plugin

If you have the Sites plugin enabled, websites built by the Expert can be published to the public internet:

1. The Expert completes website development in the sandbox
2. You confirm the result in the preview panel
3. Click the “Publish” button
4. The website is deployed to the public internet with an accessible URL
