What is Code Sandbox?

CodeSandbox is a cloud-based platform designed to provide secure, scalable, and isolated development environments for executing code. It enables users to run code in sandboxed virtual machines (VMs) without affecting their local systems, making it ideal for scenarios requiring strict security and isolation. The tool is primarily used by developers, AI researchers, and organizations needing to test, execute, or generate code at scale. It solves problems related to unsafe code execution, resource management, and the need for rapid, reliable environment provisioning. By leveraging microVM technology, CodeSandbox allows for instant code execution, resuming of sessions, and efficient handling of millions of concurrent environments. Its integration with Together AI highlights its role in enabling secure code interpretation for generative AI applications, expanding its utility beyond traditional development workflows.

How it works

CodeSandbox is a cloud service that creates isolated virtual machines for executing code securely. It is part of Together AI's ecosystem, focusing on enabling AI agents and tools to run code safely and at scale. The platform's primary purpose is to provide developers and organizations with a secure, scalable environment for code execution, testing, and generation. It ensures that untrusted or experimental code runs in isolation, preventing system-wide risks while maintaining performance and reliability. CodeSandbox supports secure code generation at scale by isolating environments, allowing millions of concurrent VMs. It uses microVM infrastructure to spin up, clone, and restore environments within seconds, enabling rapid iteration. Features like continuous context and snapshots allow resuming sessions without data loss.

How to use it

  1. 1Access the CodeSandbox platform via its web interface or integrate it with AI workflows through its SDK. 2. Define environment parameters, such as resource limits and security settings, via the API or configuration files. 3. Deploy code to the sandbox, which automatically provisions an isolated VM. 4. Monitor execution, leverage snapshots for resuming sessions, and manage environments through the dashboard or automation scripts. Practical tips include using the SDK for programmatic control, configuring hibernation schedules to optimize resource usage, and leveraging snapshot features for long-running tasks. For AI agents, ensure sandboxed environments are pre-configured with necessary dependencies to streamline code execution.

Frequently asked

What is CodeSandbox and how does it differ from traditional development environments?

CodeSandbox is a cloud-based platform that provides isolated virtual machines for secure code execution. Unlike traditional environments, it prioritizes scalability and security by isolating each sandboxed session, allowing millions of concurrent VMs. It is designed for scenarios requiring strict isolation, such as AI agents or untrusted code, whereas local development environments typically run on user machines without such safeguards.

How does CodeSandbox ensure secure code execution?

CodeSandbox isolates each code execution environment in a dedicated virtual machine, preventing interference with the host system or other sandboxes. All environments are configured with strict security policies, and untrusted code runs in a locked, resource-limited context. The platform also supports secure API integrations, ensuring that only authorized workflows can interact with sandboxed environments.

How can I run a simple script in CodeSandbox?

To run a script, first access the CodeSandbox platform via its web interface or API. Define the script's parameters and resource limits, then deploy it to a new sandboxed VM. Use the platform's SDK or CLI tools to automate this process. For example, a Python script can be executed by submitting it through the API, which provisions a VM, runs the script, and returns the output while maintaining isolation.

How does CodeSandbox compare to alternatives like Replit or Docker?

CodeSandbox focuses on secure, scalable sandboxing for code execution, particularly for AI and enterprise use cases, while Replit emphasizes collaborative coding in browser-based environments. Docker provides containerization for local or cloud deployments but lacks the built-in isolation and scalability of CodeSandbox. Unlike Docker, CodeSandbox abstracts VM management, making it easier to handle large-scale, untrusted code execution.

What should I do if my CodeSandbox environment fails to start?

If an environment fails to start, check for insufficient resource allocation or configuration errors. Verify that the requested VM size and dependencies are supported. If the issue persists, review the platform's logs for specific error codes and consult the documentation. For API integrations, ensure correct authentication tokens and endpoint configurations. Contact support if the problem remains unresolved.
