sandbox-sdk vs background-agents
Cloud sandbox SDK and background coding agents compared
sandbox-sdk provides building blocks for Workers to run code in Linux containers on Cloudflare, with file and storage operations around those environments. background-agents is a deployable system for teams to run coding agents asynchronously, connect them to collaboration tools, and use configurable sandbox providers.
sandbox-sdk: Run Sandboxed Code on Cloudflare's Edge
Cloudflare Sandbox SDK runs untrusted or generated code in Linux sandboxes built on Cloudflare Durable Objects and Containers. It gives Workers control over sandbox ownership, network access, and credentials, with tools for files, bucket mounts, and backups.
background-agents: Run Coding Agents in Background Sandboxes
Open-Inspect is a background coding agent system inspired by Ramp’s Inspect, built around Cloudflare Workers and sandbox runtimes such as OpenCode and Anthropic’s Claude Agent SDK. It connects web, Slack, GitHub, Linear, and webhook workflows to coding sessions for trusted teams.

Key differences
- sandbox-sdk focuses on container and storage primitives for application-managed sandboxes; background-agents coordinates coding-agent sessions, integrations, and team workflows.
- sandbox-sdk targets Cloudflare Workers, Durable Objects, and Containers; background-agents uses Cloudflare for its control plane and supports several sandbox infrastructure providers.
- With sandbox-sdk, the application manages sandbox selection and Container startup; background-agents requires configuring a control plane, sandbox infrastructure, integrations, and model access.
- sandbox-sdk supports workflows such as command execution, file transfer, storage mounts, and directory backups; background-agents emphasizes asynchronous coding tasks, repository changes, collaboration, and pull requests.
- sandbox-sdk reports a NOASSERTION license in repository metadata, while its README describes Apache License 2.0; background-agents lists an MIT license.
- background-agents is designed for trusted, single-tenant organizational deployments; sandbox-sdk provides building blocks for per-user, per-task, or per-session environments, with network access and authentication managed by the application.
Choose sandbox-sdk if you…
- need Cloudflare-specific building blocks for running code in Linux containers from Workers.
- want file transfer, S3-compatible mounts, or directory backups around a container environment.
- need the application to manage sandbox selection, startup, network access, and credentials.
Choose background-agents if you…
- want a deployable system for asynchronous coding-agent work across repositories.
- need session entry points through a web app, Slack, GitHub, Linear, or authenticated webhooks.
- can operate a trusted single-tenant deployment and configure its sandbox, integrations, and model access.
