How to run an exported ComfyUI workflow as simple controls with HEISS UI

Import a graph you built in ComfyUI and use it from the studio with a clean set of controls.

Short answer: Build and test the graph in ComfyUI, then export it in API format (the regular workflow file also works); then open the Workflow Gallery from the dock and drop the file on it, or paste the JSON; check the connections under Change connections, then import. All steps.

Authorization notice. HEISS UI is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.

Remote script. The import review warns about nodes that run code, touch files or go online, so read those warnings before running a workflow you did not build yourself.

Who it is forA ComfyUI user with a custom workflow who wants teammates or themselves to run it without opening the graph.

The problemA custom graph is hard to hand to someone who only needs a prompt box and a result.

The outcomeYour workflow appears in the model menu under Your workflows, with prompt, size, seed and steps as controls, while your graph runs underneath.

What you need first

  • A ComfyUI install that is running, such as ComfyUI Desktop, or reachable at a known address
  • A Windows, macOS (Apple Silicon) or Linux computer, or Node.js 20.9+ if you install from source
  • Enough disk space for the model files you choose to download

Steps

  1. Build and test the graph in ComfyUI, then export it in API format (the regular workflow file also works).
  2. Open the Workflow Gallery from the dock and drop the file on it, or paste the JSON.
  3. Check the connections under Change connections, then import.
  4. Install any nodes the workflow needs, then find it under Your workflows in the model menu.

Prompt for your agent

Using the HEISS-UI repo (github.com/tristmeister/HEISS-UI) running on a local ComfyUI, import the exported workflow file <path to workflow.json> through the Workflow Gallery and review the flagged connections. Report which inputs were guessed, which nodes run code or go online, and whether the workflow appears under Your workflows. Verify that one test render completes.

Caveat. The workflow only shows up under Your workflows after the nodes it needs are installed, so a missing node pack will hide it until you add that pack.
