Overview
CodeSandbox is a cloud development platform that provides instant, isolated development environments, known as sandboxes. These sandboxes can be spun up programmatically via APIs, making them suitable for a wide range of use cases, from individual coding projects to large-scale AI agent execution. The platform is designed to handle millions of concurrent virtual machines, offering features like snapshots, auto-resume, and customizable hibernation to manage resources efficiently.
CodeSandbox fits into the modern development ecosystem by bridging the gap between local development and cloud-based collaboration. It enables developers to code, collaborate, and ship projects of any size from any device, without the need for complex local setup. With its recent integration into Together AI, CodeSandbox is also positioned as a tool for AI-driven code generation and interpretation, expanding its utility beyond traditional development workflows.
Best for
- Developers who need instant, disposable environments for testing or prototyping without local setup.
- Teams looking for a collaborative platform to work on code in real-time, with the ability to share and review code easily.
- AI engineers and researchers who require secure, isolated sandboxes to run untrusted code or execute AI agents.
- Educational institutions or training programs that need to provide consistent development environments to many students.
- Organizations that need to run CI/CD tests in isolated, scalable environments.
Key capabilities
- Programmatic sandbox creation: Use APIs to spin up isolated development environments on demand, enabling automation and integration with other tools.
- Secure isolation: Each sandbox runs in its own isolated environment, allowing safe execution of untrusted code without affecting the host system.
- Scalability: The platform is built to handle millions of concurrent VMs, making it suitable for large-scale deployments.
- Snapshots and auto-resume: Sandboxes can be snapshotted and resumed quickly, preserving state and reducing downtime.
- Customizable hibernation: Control when sandboxes hibernate after periods of inactivity, optimizing resource usage.
- Template universe: Start with pre-configured templates for popular stacks, accelerating project setup.
Common workflows
- AI agent development: Developers create sandboxes for AI agents to resolve user prompts, run multiple agents in parallel, and use forking to A/B test different agent versions.
- Secure code interpretation: Run untrusted code in a sandbox to interpret or evaluate it, ensuring system safety. This is useful for executing code from external sources or running evals.
- CI/CD testing: Spin up sandboxes to run tests, then hibernate them when done. This allows for quick restarts when tests need to be rerun or results evaluated.
- Collaborative development: Teams use sandboxes as shared development environments, enabling real-time collaboration and code review without local setup.
- Educational environments: Instructors provision sandboxes for each student, providing consistent environments for assignments and projects.
What to evaluate
- Supported stacks and templates: Check if the available templates cover the programming languages and frameworks you use.
- Cloud vs. local workflow: Consider how the cloud-based environment integrates with your existing local development tools and version control systems.
- Collaboration features: Evaluate how real-time collaboration works, including permissions, sharing, and versioning.
- Integration with existing tools: Assess the availability of APIs and integrations with CI/CD pipelines, IDEs, and other development tools.
- Resource management and cost: Understand how sandbox provisioning, hibernation, and scaling affect resource usage and potential costs.
Getting started
- Visit the CodeSandbox website and sign up for an account.
- Explore the template universe to start a new sandbox with your preferred stack.
- Use the sandbox to write and run code, and share it with collaborators or integrate it into your workflow via the API.
