2/ CodeSandbox started back in 2017 as a React playground. With a lot of support from the community, we grew to 4.5 million monthly users in 2024. Which we never could’ve imagined and are extremely thankful for.

codesandbox.ioJoining Together AI and Introducing CodeSandbox SDKWe are starting a new chapter for CodeSandbox, building better tooling for our community.

3/ As the world entered the era of AI, we found that our VM sandboxes made for a perfect solution for executing code in agentic workflows. Both us and Together AI understood the immense potential of bringing code execution to LLMs, so we joined forces and today we’re also releasing CodeSandbox SDK.

codesandbox.iocodesandbox.ioGive agents a Devbox to resolve user prompts, or create autonomous agents running on Devboxes. You can run multiple agents in parallel without them interfering with each other. Using the forking mechanism, you can also A/B test different agents.

4/ With CodeSandbox SDK, you can programmatically spin up VM sandboxes that run inside our infrastructure. These VM sandboxes have memory snapshot/restore, fast VM cloning, FS persistence (with git version control), environment customization using Dev Containers, and more.

5/ But we’re just getting started! We have big plans for the SDK, including private previews, snapshot tagging, sessions, and an integration with Sandpack, so Sandpack can run VMs. The SDK repo is fully open source, so feel free to reach out or open an issue on GitHub!
