Link is delivered as single-tenant managed infrastructure — each instance is dedicated to one organization and serves one contract, with no multi-tenancy inside an instance. It comes in two editions that differ in what the instance is allowed to serve.

Editions

Bundled

Provisioned together with a Specter instance and locked to serving that instance’s backends. It scales automatically with the connected Specter and is billed as part of it — there is no separate Link contract.

Standalone

The full open runtime. Run any Hellgate-curated protocol, import your own protocols that conform to the Link protocol schema, and put other load through the instance — independent of Specter.
Unlocking. A Bundled instance is dedicated to its Specter instance. To run other protocols or send other load through it, unlock it into a Standalone instance — contact your account representative.
Managed backends. You operate your own backends on either edition. If you’d rather not, Hellgate can operate backends on your behalf — ask your account representative.

Tiers

Each edition runs on two environment tiers, each a separate instance:
  • Production — your live environment for real provider traffic.
  • Test — an environment for development, integration testing, and quality assurance, including mock backends that need no external provider.
Each tier is a distinct instance with its own configuration. Protocols and backends registered in Test are not shared with Production.

Getting access

To request a Link instance, contact your account representative or reach out via hellgate.io/demo. For plan and pricing details, see hellgate.io/cpa/link or contact your account representative. Once your instance is provisioned, Hellgate Support provides:
  • Your instance URL — https://{instance-name}.{env}.on-hellgate.cloud, where {env} is currently eu1 and {instance-name} is your unique slug
  • Client credentials (client ID and secret) to request access tokens
