ComfyUI
The node-based editor itself. Save a graph once, re-run it forever, and change one node without touching the rest.
ComfyUI is the node editor most serious image pipelines are built on. The ecosystem around it is about one thing: not rebuilding the same graph every time. Browse for a workflow, run it somewhere with enough VRAM, or start from a layout you already drew.

Shared ComfyUI graphs with preview images. Search here before building anything from scratch.
Workflow and model library with an editor in the browser, aimed at people who want node control without a local install.
Runs ComfyUI workflows on rented GPUs. The usual answer when the graph does not fit on your card.
Installs the custom nodes a downloaded workflow assumes you already have. The first add-on most people install.
Draw a layout and edit the MOSS-Image JSON by hand, with nothing uploaded. Useful when a workflow expects positioned elements rather than a sentence.
Draw bounding boxes on a 0–1000 grid and export the FLUX 3 layout prompt as element JSON.
Listed in the order we would try them, not by who asked. Prices and free tiers change often — check the vendor's page before you commit. Tool Pantry tools run in your browser and upload nothing.
Not strictly — it runs in the cloud too — but locally it wants a decent card. If a workflow refuses to fit, RunComfy and similar services rent the hardware by the hour.
Start with Comfy Workflows or OpenArt and search the effect, not the tool name. A working graph with a preview image tells you more than a description.
It uses custom nodes you have not installed. ComfyUI Manager installs them; after that, restart and reload the workflow.
We add tools by hand, and only ones we have actually used. Send the link with one sentence on what it does better than the alternatives.
