Local sandboxes: free (incl. commercial). Cloud sandboxes: pay-as-you-go, metered per second by vCPU+memory size, no recurring subscription fee; one-time promotional compute credit at signup; BYO model-provider keys (inference billed by your provider). Org governance: separate paid subscription (sales).

AI coding agents in isolated sandboxes (cloud SDK catalog: Claude Code, Codex, Cursor, Devin, Gemini CLI, OpenCode; Console also advertises Hermes; other dedicated agent pages describe local sandboxes) · Agents requiring a private Docker Engine, subject to documented cloud docker exec/compose exec/healthcheck filesystem limitations · Programmatic code execution via REST API and JavaScript/TypeScript SDK · Detached cloud agent tasks · On demand HTTP apps behind public HTTPS ports with account supported auto resume

- Partially supported — Exists with caveats: gated, thin, or enterprise-only.
- Not supported — Checked and not offered.
- Not assessed — Scanned before this capability was tracked. Not a lack.

Proposed, not verified
Capabilities the scan saw but the registry does not track yet. A key is admitted only once two distinct products exhibit it. These are not scored.
- Private Docker Engine inside every sandbox (agents can docker build / compose up without a host socket mount)nested-docker-engine
“Every sandbox has its own Docker Engine. Build, run, compose. No socket mounting, no host privileges.” docker.com
- Copy a sandbox filesystem between local and cloud (sbx move; not memory/process migration)local-cloud-portability
“It doesn't transfer running processes or memory, and it leaves the source sandbox in place.” docs.docker.com

Plausible compatibility 7
Derived, not stored: the product passes SSH access, so any CLI coding agent is installable inside it. This is plausible compatibility, not a supported integration.

08 Sources & method How this entry was produced
Public surface only
Everything here was read from docker.com's unauthenticated pages, docs, pricing and repository on 8 Oct 2026. Nothing behind a login was used.
Statuses, not scores
Capabilities are pass, partial or fail against a written rubric (features v21). “Not assessed” means the scan predates the key.
Confidence is separate
Each fact carries its own confidence. Low-confidence facts are shown, never hidden, so you can weigh them.
