Working workflow
You bring an existing ComfyUI workflow that already produces the result your product or customer project needs.
Productionization handled for you
Your workflow works. We make the runtime ready.
A working ComfyUI workflow is the starting point. Comfy Rail turns its models, custom nodes and dependencies into a reproducible, tested and maintained RunPod Serverless runtime behind a documented API.
01 · What you bring
Start with the creative result you already proved.
Product requirements
You identify the required models and custom nodes, expected inputs and outputs, image limits and the product scenario the runtime must support.
02 · What Comfy Rail handles
We take on the infrastructure project behind the workflow.
Runtime mapping
We map the agreed workflow contract, models, custom nodes, package dependencies and target GPU profile into a bounded runtime specification.
Reproducible build
We pin compatible revisions, package the agreed stack and record model and component provenance for the intended commercial use.
RunPod integration
We prepare the image, endpoint configuration, API behaviour, input and output paths, health checks and supported RunPod deployment profile.
Runtime verification
We test reference inputs, validation failures, cold and warm execution, resource use, timeout behaviour and the accepted serverless path.
03 · What you receive
Acceptance is based on evidence, not a container tag.
Verified delivery
You receive private access to the agreed runtime image, its immutable digest, deployment guidance, the documented API contract and reference-test results.
Release boundary
The release record identifies supported profiles, known issues, component and model inventory, documented changes and the rollback path.
Technical acceptance
Each used runtime profile is verified with the agreed workflow and at least one complete RunPod job before technical acceptance.
Maintained runtime
After acceptance, Comfy Rail maintains the agreed release boundary through compatible updates, release notes and runtime-defect support.
04 · Who owns what
Clear responsibility after deployment.
Comfy Rail
Runtime engineering, packaging, RunPod integration, verification, release evidence and maintenance of the accepted stack.
Your organisation
The creative workflow and target result, integration of the documented API, users, billing, customer experience and product operation.
RunPod
GPU capacity, platform availability, regions, storage, network services and direct infrastructure billing through your own provider account.
