Daytona

Daytona is secure, elastic infrastructure for running AI-generated code. Daytona provides isolated sandboxes that spin up in milliseconds, giving your agents a safe place to execute shell commands, run code, work with files, and clone repositories — without ever touching your own machines.

Why Daytona?

  • Built for AI-generated code: Sandboxes are fully isolated runtimes, so untrusted or generated code can run safely with no risk to your infrastructure.
  • Fast, elastic sandboxes: Create a sandbox in under a couple hundred milliseconds, use it for one task or keep it alive across a whole session, and let auto-stop and auto-delete intervals clean up after you.
  • Complete toolbox: Execute shell commands, run Python, JavaScript, or TypeScript with a built-in code interpreter, transfer files in and out, and clone Git repositories — all through one API.
  • Programmatic lifecycle control: Create, list, start, stop, and delete sandboxes on demand, with snapshots, regions, resource sizing, environment variables, and labels.

Using Daytona in Sim

Sim's Daytona integration connects your workflows to Daytona with an API key. Twelve operations cover the full sandbox lifecycle and toolbox: create, list, get, start, stop, and delete sandboxes; run code and execute commands inside them; upload, download, and list files; and clone Git repositories.

Key benefits of using Daytona in Sim:

  • Safe code interpreter for agents: Let an agent write Python, JavaScript, or TypeScript and execute it in an isolated sandbox, then use the output downstream in your workflow.
  • Real file handling: Upload workflow files directly into a sandbox, process them with code or commands, and download the results as files other blocks can consume.
  • Repository automation: Clone a repository into a sandbox, run installs, builds, or tests, and report the results — perfect for CI-style checks and repo health monitoring.
  • Cost-aware lifecycle: Create sandboxes on demand, stop or delete them when work finishes, and use auto-stop intervals so idle sandboxes never run up your bill.

Whether you're building an AI code interpreter, validating generated code before it ships, analyzing data files in a clean environment, or automating repository checks, Daytona in Sim gives your agents real compute with strong isolation. Configure your API key, pick an operation, and start running code.

Usage Instructions

Integrate Daytona into your workflow to run AI-generated code in secure, isolated sandboxes. Create and manage sandboxes, execute shell commands, run Python, JavaScript, or TypeScript code, transfer files, and clone Git repositories.
