Shadow

Shadow is a French cloud computing company founded in 2015, launched commercially in 2016, and chaired by OVHcloud founder Octave Klaba. It streams complete high-end Windows desktops (Shadow PC, Shadow PC Pro), sells Nextcloud-based storage as Shadow Drive, and sells sovereign GPU compute as Shadow GPU — an OpenStack 2024.1 platform running across seven regions in France, Germany, the United States and Canada. Shadow GPU is programmable only through the standard OpenStack API: a Keystone v3.14 identity endpoint answers anonymously at https://auth..os.shadow.tech/v3, fronting Nova (compute), Neutron and Octavia (networking / load balancing), Designate (DNS), Cinder and Glance (storage and images), Placement, Barbican (secrets), CloudKitty (rating) and the Skyline / Horizon dashboards, driven with the upstream openstack CLI, Terraform, Ansible, Pulumi or Cluster API. Shadow publishes no OpenAPI, AsyncAPI, first-party SDK, MCP server or A2A agent card of its own.

Shadow publishes 1 API on the APIs.io network. Tagged areas include Company, Cloud Computing, GPU, Cloud Gaming, and Infrastructure.

Shadow’s developer surface includes documentation, getting-started guide, support, engineering blog, pricing, authentication, and 13 more developer resources.

scored 2026-09-08 · rubric v0.20.0
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/shadow: open an issue to ask a question, or submit a pull request to add artifacts.

  description: 'Shadow GPU is Shadow''s sovereign GPU cloud, delivered as a curated OpenStack 2024.1 deployment rather than
    a bespoke REST API. Every programmatic action — launching NVIDIA RTX 2000 Ada or RTX A4500 GPU instances, attaching Cinder
    volumes, wiring Neutron networks and Octavia load balancers, managing Barbican secrets, reading CloudKitty usage — is
    performed against the standard OpenStack service APIs. Authentication is Keystone: a domain-scoped user (user#domain)
    or, for automation, an Application Credential, delivered as a clouds.yaml or openrc.sh downloaded from the dashboard.
    The Keystone identity endpoint answers anonymously and self-identifies at https://auth.<region>.os.shadow.tech/v3; the
    rest of the service catalog is returned only inside an authenticated token response, so per-service endpoints are not
    publicly enumerable. Shadow publishes no OpenAPI document for this surface and points users to the upstream OpenStack
    API reference.'
