CodeSandbox
CodeSandbox is an online code editor and prototyping tool that makes creating and sharing web apps faster.
About CodeSandbox
CodeSandbox provides cloud-based development environments and infrastructure for running code in isolated sandboxes. Its SDK allows programmatic creation of these sandboxes, which run as microVMs that can start or restore from a snapshot within seconds and hibernate after configurable periods of inactivity. The platform also offers Sandpack for live in-browser coding and a Storybook integration for embedding code playgrounds into component stories.
The product targets use cases including AI agents that need isolated execution environments (including running multiple agents in parallel or forking sandboxes for A/B testing), secure interpretation of untrusted code, running evals, CI/CD test execution, and providing individual development environments for students or developers at scale. CodeSandbox is part of Together AI, following the companies joining forces to launch the CodeSandbox SDK for code interpretation in generative AI applications.

Frequently asked questions
What is CodeSandbox used for?
CodeSandbox provides instant cloud development environments and sandboxes for prototyping, learning, CI/CD, and running AI agents. It also offers a Storybook integration and browser-based live coding via Sandpack.
Is CodeSandbox safe for running untrusted code?
Yes, every sandbox environment runs in isolation via microVMs, so untrusted code can run without affecting the host system.
Can CodeSandbox scale for many concurrent environments?
Yes, its infrastructure is built to handle millions of concurrent VMs, making it easy to provision, manage, and decommission them at scale.
Who owns CodeSandbox?
CodeSandbox BV is a Together AI company, following CodeSandbox joining forces with Together AI to launch the CodeSandbox SDK.
How is CodeSandbox used with AI agents?
AI agents can be given sandboxes to resolve user prompts or run autonomously, with support for running multiple agents in parallel without interference, including A/B testing via forking.
