About CodeSandbox
Overview
CodeSandbox is a cloud development platform that enables developers to code, collaborate, and ship projects from any device. It provides instant development environments accessible through a web browser without requiring local setup or installation.
The platform addresses the friction of environment setup by offering pre-configured sandboxes where developers prototype ideas, run untrusted code safely, and collaborate in real time. CodeSandbox targets web developers, AI engineers building agents, educators, and teams needing scalable development environments.
Key Benefits
- Spin up isolated development environments in 2 seconds using microVM infrastructure.
- Run untrusted code safely in isolated sandboxes without affecting your system.
- Resume development instantly after inactivity through continuous context snapshots.
- Scale to millions of concurrent VMs while managing and decommissioning environments programmatically.
- Integrate with Storybook to embed live code playgrounds directly into documentation.
- Deploy AI agents with parallel execution and A/B testing through sandbox forking.
How It Works
You create a sandbox environment and write or paste code into the browser-based editor. The platform executes your code instantly within an isolated VM, and you can snapshot your work. When you return later, CodeSandbox restores your snapshot within the same sandbox, preserving all context and state.
Use Cases
- AI engineers deploying autonomous agents that resolve user prompts inside sandboxes without interfering with each other.
- Web developers prototyping frontend frameworks and experimenting with new tools before committing to production.
- Educators creating a separate sandbox for each student, allowing code execution in isolation across a class.
- Documentation teams embedding interactive code playgrounds in Storybook stories for readers to edit and run live.
- CI/CD operators running tests inside sandboxes and hibernating them to speed up re-runs when evaluating results.
- Security researchers and code evaluation platforms running untrusted code and popular evals with full isolation.
