computer vs sandbox-sdk
Cloudflare agent workspaces and code execution compared
computer provides a durable workspace with optional container or Worker execution. sandbox-sdk focuses on running code in Linux containers, with file transfer and storage operations managed around those containers; the Worker owns sandbox selection and startup.

computer: Give Agents a Durable Virtual Filesystem and Runtime
Cloudflare Computer gives agents a virtual filesystem backed by SQLite in Cloudflare Durable Objects, with execution through Workers or Linux containers. It suits developers building agent workspaces that need persistent files and a choice of runtime.

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.

Key differences
- computer stores authoritative filesystem state in Durable Object SQLite and can be used without an execution backend; sandbox-sdk centers on running code in Cloudflare Containers.
- computer offers container, Worker shell, and JavaScript Worker execution backends; sandbox-sdk focuses on Linux containers.
- sandbox-sdk includes file transfers, S3-compatible mounts, and directory backups to R2; computer emphasizes a persistent workspace shared across execution backends.
- computer is explicitly preview-only, with unstable APIs and no production recommendation; sandbox-sdk's version 1.0 requires the application to manage the Durable Object and start the Container.
- Both are written in TypeScript and target Cloudflare services; sandbox-sdk reports `NOASSERTION` metadata while its README describes Apache License 2.0, and computer reports an MIT license.
Choose computer if you…
- need durable workspace files that persist across executions.
- want to compare container and Worker-based execution against the same workspace.
- are prototyping agent workflows on Cloudflare and can work with preview-only APIs.
Choose sandbox-sdk if you…
- need to run generated or untrusted code in Linux containers on Cloudflare.
- want Worker-managed file transfer, S3-compatible mounts, or directory backups to R2.
- need per-user or per-task sandboxes and are prepared to manage sandbox selection and Container startup.
