What is Orca?
An open runtime for managed agents. You declare an agent, deploy it, and drive it through the API, the CLI or the SDKs. Every model and tool call travels through a governed gateway, and every step is appended to a log the session can replay from.
Is Orca open source?
Yes. Orca Agent Engine is open source under Apache-2.0. The AI Gateway runs beside it as a Docker image, and the docs cover getting started with both.
What does Orca cost, and is there a hosted version?
Orca Agent Engine is free and open source under Apache-2.0, and you run it yourself. StreamNative Cloud also offers it as a managed, Workspace-scoped service.

How does Orca relate to Claude Managed Agents?
Orca Agent Engine mirrors the Claude Managed Agents API surface, so Anthropic-compatible clients can point their base URL at an Orca workspace. The conformance matrix lists which operations Orca implements. Claude Managed Agents is an Anthropic product; Orca is a separate open-source project.

Which harnesses and models does Orca support?
Harnesses available now: Claude Agent SDK, Claude Code, Codex, Pi and your own harness from a JSON spec. Model providers available now: Anthropic, OpenAI, Azure OpenAI, Bedrock, Vertex and any OpenAI-compatible endpoint. Model calls go through the Orca AI Gateway.
Does Orca work with Claude Code?
Yes. Claude Code is one of the harnesses Orca Agent Engine runs, available now in the Developer Preview. The harness is a field on the Agent, so swapping it is one line.
Can I self-host Orca, and on what?
Yes. Orca Agent Engine runs where you run: the control plane and the event log stay with you. Clone it and bring up the local stack. Event stores: Kafka, Postgres or Pulsar. Sandboxes available now: E2B, local and OpenSandbox. On the roadmap: Cloudflare.
Self-hosted deployment
How is Orca different from a framework, or from a hosted agents API?
A framework is a library you still have to run. A hosted agents API brings its own harness and its own models. The pluggable platforms run several harnesses but keep the control plane — their service, their account, their audit trail. Orca is the layer underneath, and it is yours.
What's the current availability?
It is a developer preview: clone it, bring up the local stack and run agents today. roadmap.md lists the work still in progress, so read it before you plan a production rollout.
Who is behind Orca?
Orca is an open-source project sponsored by StreamNative. Orca Agent Engine is built in the open, in the orca-ae organization on GitHub.
