The ComfyUI workspace plugin that worked itself out of a job

What it does

Comfyspace was a browser extension for ComfyUI that turned the node-based UI into something resembling an IDE workspace. It saved workflows to disk, tracked version history like a lightweight git, organized subworkflows via drag-and-drop, and added a model browser that could install checkpoints from Civitai with one click. Everything lived in a side panel inside the ComfyUI tab.

The interesting bit

The project treated a generative-AI web UI like a software project, complete with folder-based organization, two-way filesystem sync, and per-workflow asset galleries. It proved the concept so thoroughly that ComfyUI eventually built the same ideas into its core frontend, rendering the extension obsolete in April 2025.

Key highlights

• Workflow version history with instant revert to any past save
• Drag-and-drop subworkflow insertion into active graphs
• One-click model installation from Civitai with thumbnail previews
• Two-way sync between the browser workspace and a local /my_workflows folder
• Per-workflow image and video galleries with cover-photo selection

Caveats

• Declared obsolete in April 2025; the maintainer announced ComfyUI’s native workspace manager replaces it and stopped maintenance
• Version history and gallery metadata are stored in browser IndexedDB, so switching browsers strands your project history
• Safari is explicitly unsupported; Chrome is recommended

Verdict

Existing ComfyUI users who relied on this should treat it as a migration notice and move to the native workspace tools. For everyone else, it’s a useful snapshot of what happens when a community plugin prototypes features so well that the core project absorbs them.
