Daytona is an open-source infrastructure layer for running AI-generated code inside isolated sandboxes. You create a sandbox through its CLI, API, or SDKs, run code inside it, inspect the filesystem and processes, and tear it down when the task is done. The current product is aimed at LLM agents and automation systems rather than interactive developer workspaces.
The original project (daytonaio/daytona v0.x) positioned itself as a self-hosted alternative to GitHub Codespaces and Gitpod, built around the open devcontainer.json standard. In 2024 Daytona pivoted toward AI sandboxes, and the current SDKs are available for Python, TypeScript, Ruby, and Go. The underlying engine still provisions isolated container-based environments, but the product focus is now secure programmatic code execution.
In the CDE space it sits alongside Gitpod, Coder, DevPod (which has a similar devcontainer-based model), and GitHub Codespaces. For AI agent sandboxing it overlaps with E2B and Modal.
