Sandbox

Secure, isolated execution environments for running AI coding agents. Every task runs in its own containerized sandbox with pre-configured tools and languages.

Sandbox Types

Choose the right sandbox size for your workload. Start small for quick tasks or scale up for demanding builds and complex operations.

Small

  • Fast startup times
  • Cost-effective for most workflows

Custom

  • Configure your own instance specifications
  • Choose memory, storage, and CPU resources
  • Install custom tools and dependencies
  • Tailored to your specific requirements
