CodeSandbox SDK Alternative for AI Agents

CodeSandbox SDK is a platform designed for creating programmable development environments, offering features like sandboxed development, concurrent VMs, and AI agent runtimes. While it excels in providing fast, isolated environments for quick code execution and browser IDE setups, its limitations become apparent when more durable, long-lived environments are required. Freestyle VMs serve as a robust alternative, offering a hardware-virtualized Linux environment that supports long-running tasks, persistent state, and complex agent workspaces. These VMs enable SSH access, parallel forking, and the ability to route HTTPS traffic, making them ideal for products that require a seamless integration of user and agent interactions in a real Linux environment. The choice between CodeSandbox SDK and Freestyle depends on whether the primary need is for quick, transient execution or a comprehensive, persistent workspace that can support AI coding agents, application building, and internal automation tools.
