GitHub Codespaces
Verified
Microsoft-hosted dev VMs that agents and humans already share.
GitHub Codespaces gives each workspace a cloud VM defined by a devcontainer. Humans use it as a remote IDE. Factories use it because the agent can get the same environment as CI-ish setup without a new vendor. It is a sandbox by accident of product history.

Editorial take
Codespaces is the sandbox you already pay for if you are on GitHub. It is not designed as an untrusted-code microVM product. Treat it as a warm, privileged workspace. Do not confuse it with Copilot’s coding agent just because both say GitHub.
Strengths
- devcontainer.json as the environment spec, shared with humans.
- Lives next to the repo and PR.
- No second vendor for basic remote compute.
Limitations
- Not a least-privilege exec API like E2B.
- Cost and idle policy are easy to get wrong.
- GitHub-only.
