Cloud Based Coding Platform With AI Coding Assistant

What is CodeSandbox and what is CodeSandbox SDK?
CodeSandbox is a cloud-based development platform that runs code inside isolated sandboxes, enabling development, testing, and sharing from anywhere. It’s now part of Together AI, which has launched CodeSandbox SDK to bring code interpretation to generative AI. The SDK lets you programmatically spin up isolated sandboxes that can run any type of code, making it ideal for AI agents and scalable code playgrounds. Key capabilities include secure, isolated environments; scale-ready infrastructure for millions of concurrent VMs; continuous context through snapshots; fast start/auto-resume (sandboxes can be cloned and restored within about 2 seconds); support for AI agents (including parallel execution and forking for A/B testing); a Template Universe with popular stacks; and tools like AI code completion, a VS Code extension, and Sandpack.
What is a sandbox and how does it work?
A sandbox is an isolated development environment that runs code without affecting your main system. Each sandbox operates in isolation, so untrusted or experimental code can be executed safely. CodeSandbox uses microVMs, allowing you to create sandboxes from templates or from scratch, clone them, and restore them from snapshots. Sandboxes provide continuous context, so development can resume after periods of inactivity with no loss. You can start, clone, and restore sandboxes quickly to support fast iteration.
How fast can sandboxes start and resume, and how scalable is CodeSandbox?
Sandboxes can be started, cloned, and restored from snapshots within about 2 seconds. The platform is designed to scale, handling millions of concurrent VMs with straightforward provisioning, management, and decommissioning. This enables rapid, scalable development workflows in AI and software projects.
What can I use CodeSandbox sandboxes for?
- AI agents: give agents a sandbox to resolve prompts, run multiple agents in parallel, and fork for A/B testing.
- Development environments at scale: create a sandbox for each developer or student and run many in parallel without interference.
- CI/CD: run tests inside a sandbox and hibernate the sandbox when tests are done, then start it again when needed.
- General code interpretation and evaluation in a safe, isolated environment.
What is the Template Universe and what templates are available?
CodeSandbox offers a Template Universe to get you started quickly. You can begin with stacks like Angular, Docker, HTML + CSS, JavaScript, Next.js, Next.js + Postgres, Python, and React, among others. The universe also includes features like AI code completion (powered by Codeium), a VS Code extension, and Sandpack to accelerate prototyping and development.
What integrations and tools does CodeSandbox support?
- GitHub integration for seamless review and deployment of code
- VS Code Extension for a familiar development experience in the cloud
- Sandpack for fast, in-browser code editing
- AI code completion powered by Codeium
- Dev Containers that pre-configure environments with necessary tools and libraries
- Storybook integration and other ecosystem integrations
How can I get started for free?
You can start for free by signing up. Explore the Template Universe to begin with your preferred stack, and use sandboxes directly in your browser or through the VS Code extension to fit your workflow.
