Hosted plan fee plus metered base running time, active vCPU, RSS memory, used disk and egress. Standard $0, Pro $20/month, Startup $150/month, Enterprise custom. OSS engine free under Apache-2.0 plus own infrastructure.
- Free tier
- Not documented
Standard has $0 monthly plan fee and one-time $100 signup credit, no card. Pricing page + public JSON agree; cloud quickstart still says $10 monthly free usage, so recurring free credit is not treated as current.

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.

05 Coding harnesses Which agents and IDEs are documented to run here
Advertised integrations 1
- Codex CLI OpenAISupported
Advertised via a prebuilt registry base machine (a ready-to-run .smolmachine), not a bespoke integration.
Plausible compatibility 0
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.
No general shell access documented, so nothing is derived. Absence is not unsupported.
06 Compliance & regions Standards held, with ordinal rigor; never a score
Certifications held 2
- CCPAself-attestedhostedSelf-attested; hosted service only.
- GDPRself-attestedhostedSelf-attested in the privacy policy (rights honoured); no third-party report. Hosted service only — the OSS engine you run yourself is outside this scope.

Apache-2.0 engine is free plus operator hardware/infra. Linux x86_64/aarch64 needs KVM; macOS needs Hypervisor.framework entitlements; native Windows x86_64 needs WHP. Standalone engine/CLI/serve API has no production fleet scheduler, placement, failover, tenant management, billing or managed durability. GPU is local/self-host only: Vulkan host stack or NVIDIA driver for CUDA remoting; GPU sharing is not hardware-partitioned multi-tenant isolation. Branch/checkpoint limits depend on host, runtime version and attached devices; Windows branches require --freeze-source.

09 Sources & method How this entry was produced
Public surface only
Everything here was read from smolmachines.com's unauthenticated pages, docs, pricing and repository on 12 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.
