Frustrated with ComfyUI, Developer Spent a Year Building Open-Source App Stimma
stimma · reddit · 2026-08-06
As generative AI workflows become increasingly complex, the native ComfyUI falls short in areas like file management and multi-GPU scheduling. To address this, the author spent a year developing Stimma, an open-source desktop application designed to create a more efficient media production environment.
Core Features & Highlights
- Asset & Index Management: Tackling the chaos of generated files, Stimma indexes media using CLIP + AuraFace embeddings, supporting tags, boards, and Lightroom-style multi-dimensional search.
- Multi-GPU Load Balancing: Includes a custom ComfyUI node pack that transforms workflows into tools accessible by both humans and agents, with load-balancing across multiple ComfyUI instances.
- Agentic Orchestration: Features a built-in chat window interface allowing AI agents to take over tedious tasks and iteratively work on text-based formats like HTML and SVG, bringing the coding agent experience to media creation.
- Stimma Tools Protocol (STP): Described as an MCP for media tools. The protocol is fully open-source with reference implementations in multiple languages, currently adapting around 30 popular ComfyUI workflows.
