Open-source ComfyUI extension loads Civitai workflows in one click, auto-downloads missing models
Zealousideal-Bee-300 · reddit · 2026-10-02
A developer released ComfyUI-Civitai-Browser (MIT licensed), solving the familiar pain of downloading a Civitai workflow only to face red nodes and 20 minutes of hunting for models.
Key features:
- Browse Civitai inside ComfyUI's sidebar: workflows, checkpoints, LoRAs, embeddings, ControlNet, VAE, upscalers, with search, sorting, base-model filter and an NSFW toggle (off by default)
- One-click "Load & Set Up": downloads the workflow, loads it on canvas, and scans it for every required model
- Automatically downloads missing models into the exact folder and filename the workflow expects; also accepts pasted Civitai/Hugging Face links
- Lists missing custom nodes for ComfyUI-Manager install
- Saves workflows to My Library; safe delete only removes models downloaded for that workflow
No new nodes, no core file modification, no extra Python dependencies; the optional API key is only sent to civitai.com. Known limitation: Civitai search works on model names, so some models still need a pasted link.
