Sandbox0

Sprites by Fly.io is a stateful sandbox platform for running arbitrary code in hardware-isolated Linux environments. A Sprite acts like a persistent Linux computer where developers can execute AI agents, user-uploaded binaries, scripts, applications, and other workloads. The platform supports checkpoint and restore, allowing environments to persist and resume instead of starting from scratch each time. Sprites use fast directly attached NVMe storage that continuously syncs to durable external object storage. Developers can create, manage, execute commands, and connect to Sprite consoles through the CLI, REST API, JavaScript, Go, Elixir, and Python tooling. Built for developers and AI infrastructure teams, Sprites gives applications a simple place to safely run code with persistence, sandboxing, usage-based pricing, and scalable execution.

ComputeSDK is a free and open-source toolkit designed to enable developers to safely run external or user-generated code within their applications through a unified and consistent interface. It provides a TypeScript-native API that abstracts multiple compute providers, allowing developers to switch between environments such as E2B, Vercel, Daytona, Modal, and others without modifying their core codebase. It is built around isolated sandbox environments, which ensure that executed code runs securely without impacting the host infrastructure, making it suitable for applications that require controlled execution of untrusted code. ComputeSDK supports key capabilities such as executing code and shell commands, managing filesystems, creating and destroying sandboxes, and integrating with modern web frameworks like Next.js, Nuxt, and SvelteKit.
