Introduction
CodeSandbox Cloud Development Infrastructure
- Core Functionality: Provides APIs to create isolated, secure microVM-based development environments (sandboxes) for running any type of code.
- Performance & Speed: MicroVM infrastructure allows for spinning up, cloning, and restoring snapshots within 2 seconds.
- Scalability: Capable of handling millions of concurrent VMs with easy provisioning, management, and decommissioning.
- Persistence: Supports state snapshots and resume-from-inactivity features; users can control auto-hibernation settings.
- Security: Environments are fully isolated, allowing for the safe execution of untrusted code without impacting the host system.
- AI & Agent Support: Designed for AI agents to resolve prompts or run autonomously; supports parallel agent execution and A/B testing via forking.
- Use Cases:
- Parallel development environments for teams, students, or individual developers.
- Running code interpreters and automated evaluations/tests.
- Building full-scale projects in an online editor environment.
- User Feedback: Highly regarded for its performance under high load, local-like development experience, and productivity improvements compared to traditional IDEs like VS Code.
