Cue is the runtime under Forge.
Forge is the codegen agent product. Cue is the open-source runtime Forge runs on — namespaces, secrets, triggers, MCP, and sandboxed execution. We operate Cue ourselves so Forge customers don't have to think about it. If you want the bare runtime without the codegen layer on top, you can self-host it.
You're a vertical SaaS platform and want to ship a codegen extension layer to your customers — scoped per customer, sandbox-safe, with the build-time agent harness, capability registry, lifecycle, and event delivery handled for you.
Request access →You're a developer building your own agent and want a runtime for tool calls, secrets, scheduled tasks, and isolated state — one namespace at a time. Self-host, no multi-tenancy needed, no codegen harness needed.
