Wildcard Pipeline
Modular procedural prompt generation — wildcards, fixed values, combines, derivations and constraints resolved in a context pipeline, with a manager UI for a reusable module library.

When Your Wildcard Picks the Resolution, Not Just the Words
Plain wildcards pick every part of a prompt on its own, so you get a snowy beach at noon under the stars. Wildcard Pipeline builds the prompt step by step, and each step can see what the earlier ones picked. If the weather comes out as rain, the mood can lean gloomy and the lighting can follow. Every Generate gives you a fresh prompt that still hangs together.
Install
- ComfyUI Manager (recommended): search for Wildcard Pipeline by dumiflex, click Install and restart ComfyUI.
- By hand: download the zip from the
latest release,
unzip it into
ComfyUI/custom_nodes/and restart ComfyUI.
A git clone has no built frontend, so you need Node.js and pnpm:
cd ComfyUI/custom_nodes
git clone https://github.com/DumiFlex/ComfyUI-Wildcard-Pipeline
cd ComfyUI-Wildcard-Pipeline
pnpm install
pnpm build
Quick start
- Open the Wildcard Pipeline manager from the ComfyUI sidebar and create a
wildcard called
subjectwith three options:a cat,a dog,a fox. - On the canvas, chain WP Context → WP Prompt Assembler →
CLIP Text Encode. Add your wildcard to the Context node and type
a photo of $subjectinto the Assembler. - Queue a few times. Each run picks a new subject.
The Quick Start wiki page walks through a fuller example.
How it works
You stack modules inside a WP Context node. Each module sets one or more
$variables, and the WP Prompt Assembler drops them into your template.
| Module | What it does |
|---|---|
| Wildcard | Picks one option from a weighted list. |
| Fixed Values | Sets variables to values you choose, like a style or quality tags. |
| Combine | Builds one variable out of others, e.g. $style $subject. |
| Derivation | If/else rules: "if $weather is rain AND $time is night, set $lighting to neon". Conditions can be grouped with AND / OR. |
| Constraint | Makes an earlier pick change the odds of a later one, or rule options out entirely. |
| Bundle | A saved group of modules you can drop in as one piece. |
Options can point at other modules with @name, so a wildcard can nest another
one. If the module you want doesn't exist yet, pick Placeholder from the @
list and connect it later.
Nodes
| Node | What it does |
|---|---|
| WP Context | Holds your module stack and outputs the picked variables. Chain several together. |
| WP Prompt Assembler | Fills $variables in a template. Also supports inline {a\|b\|c} picks. |
| WP Context Loop + WP Seed List | Run the whole chain N times from one Generate, each with its own prompt and seed, or sweep every combination of chosen wildcard options. |
| WP Context Injector | Turns any ComfyUI output (text, a number) into a $variable. |
| WP Model Info | Reads the loaded checkpoint into $model_family / $model_variant (Pony, Illustrious, …) so rules can pick LoRAs and tags per model. |
| WP Image Filter | Pauses the run so you pick which images go on to the upscaler. Their latent, conditioning, prompt text and Context are filtered with them, and you can edit a prompt or paint a mask before they go on. |
| WP Prompt Cleaner | Tidies the final prompt: spacing, stray commas, empty (), nested weights, LoRA tags, duplicates, a blocklist. |
| WP Debug | Shows what happened during a run (see below). |
| WP Var → Int / Float / Bool | Use a variable to drive a number or switch, like image size or steps. |
Most nodes have a help page in ComfyUI's node info panel, and the wiki covers nodes, modules and concepts in depth.
The manager
Open it from the ComfyUI sidebar. It's where your modules live between workflows.
<p align="center"> <img src="public/images/docs/spa_manager.png" alt="Wildcard Pipeline manager dashboard with module counts, quick create buttons and recently opened items" /> </p>- Library: create, edit and search your modules, bundles and prompt templates. The Tags page groups them into collections, and you can rename or merge a tag across the whole library.
- Test Runner: try a set of modules over many seeds without generating images. See how often each option comes up and which rules fired, save a baseline, and after an edit see exactly which outputs changed.
- Community: browse and install modules other people have shared on the community site, and publish your own.
- Import / Export: move modules between machines as JSON files, or bring in
wildcard packs from A1111 or Forge on the Wildcard packs tab. Dynamic Prompts,
PPP and Impact Pack
.txt,.yamland.jsonfiles (or a.zipof them) become wildcards, with__references__turned into links. A folder of related lists merges into one wildcard whose options are tagged by list, with a tag group per folder level. You review the plan first (each wildcard's role, what was merged and how exactly it carries over), and the pack's entry points are filed into bundles per folder. - Documentation: the full guide, built into the app.
Checking a run
Connect WP Debug to a Context node and generate. It shows:
- Variables: every value, and which step set it.
- Trace: each step, and why it did what it did: which derivation rule fired, a wildcard's odds and what re-weighted them, where a nested pick came from.
- Warnings: anything that went wrong, linked to the step that caused it.
- Raw: the underlying data, for bug reports.
Help and sharing
Discord is the place for all of it: there are channels for questions, bug reports, feature requests and showing what you made. You can also report bugs on GitHub Issues.
Made something you like? Post your images and workflows on Discord, and publish your modules on the community site so others can install them from the manager's Community page.
Privacy
Everything runs locally. The extension only goes online to check for updates (you can turn this off in Settings), when you open the Community page, or when you choose to download the optional tag list for autocomplete. Details are in docs/network-access.md.
