+# Reflection: ComfyUI Integration (Level 2)
+
+## Summary
+Added ComfyUI as an optional service using Docker Compose profile `comfyui`, proxied via Caddy at `COMFYUI_HOSTNAME`. Default CPU support, optional GPU planned. Updated `.env.example`, `docker-compose.yml`, `Caddyfile`, `scripts/04_wizard.sh`, `scripts/06_final_report.sh`, and `README.md`.
+
+## What Went Well
+- Followed existing installer patterns (profiles, Caddy host blocks, env generation/wizard/reporting) with minimal, clear edits
+- Simple reverse proxy through Caddy; WebSocket support expected to work without extra config
+- Compose config validated successfully
+
+## Challenges
+- No single “official” Docker image; community images differ in volume layout and flags
+- Volume paths for models/output/custom_nodes vary by image; chose a conservative mount point for persistence
+- GPU enablement requires NVIDIA toolkit and compose device reservations (not universally available)
+
+## Lessons Learned
+- Keep defaults CPU-first to minimize friction; add GPU as an opt-in
+- Abstract image details behind a validation checklist (port 8188, volume paths, CLI flags)
+- Document model storage and persistence expectations explicitly
+
+## Improvements / Next Steps
+- Consider adding a GPU-specific profile variant (e.g., `comfyui-gpu-nvidia`) when environment supports it
+- Evaluate switching to a more widely adopted/maintained image and standardize volume mappings
+- Extend final report with quick pointers to model directories and basic usage tips
+
+## Verification Checklist
+- Implementation reviewed end-to-end: YES
+- Successes documented: YES
+- Challenges documented: YES
+- Lessons learned documented: YES
+- Process/Technical improvements identified: YES
+
+## Impact
+- New optional service enabling visual Stable Diffusion workflows in the installer with minimal complexity

+## New Task: Add ComfyUI Service (Node-based UI for SD Workflows)
+
+### Description
+Integrate ComfyUI as an optional service in the installer, proxied by Caddy at a configurable hostname. Default to CPU-only for simplicity; allow optional GPU via NVIDIA Container Toolkit if present.
+
+### Complexity
+- Level: 2 (Simple Enhancement)
+- Type: Add-on service via Docker Compose profile + Caddy
+
+### Options Considered (Research)
+- Dockerized ComfyUI service using a maintained community image (e.g., ghcr.io/ai-dock/comfyui or equivalent)
+- Bare-metal Python install managed by scripts (higher maintenance, not aligned with project patterns)
+- Integrate as an extension of AUTOMATIC1111 (not applicable to this project’s stack)
+- Build our own image from source (heavier maintenance)
+
+→ Recommended: Use a maintained ComfyUI Docker image exposing port 8188, mount persistent volumes for models and custom nodes, reverse-proxy with Caddy. GPU support remains optional via compose flags when host supports NVIDIA.
+
+### Technology Stack
+- Image: Maintained ComfyUI Docker image (to be validated during tech gate)
+- Port: 8188 (internal)
+- Reverse proxy: Caddy with HTTPS at `COMFYUI_HOSTNAME`
+- Storage: Named volume `comfyui_data` (models, input, output, custom_nodes)
+- GPU: Optional via NVIDIA toolkit (compose device reservations)
+
+### Files to Modify
+- `.env.example`: add `COMFYUI_HOSTNAME`
+- `docker-compose.yml`: add `comfyui` service with `profiles: ["comfyui"]`, volumes, healthcheck, optional GPU stanza
+- `Caddyfile`: add host block for `{$COMFYUI_HOSTNAME}` → `reverse_proxy comfyui:8188`
+- `scripts/04_wizard.sh`: add `comfyui` option with description
+- `scripts/06_final_report.sh`: add ComfyUI section with URL
+- `scripts/03_generate_secrets.sh`: generate default hostname `COMFYUI_HOSTNAME`
+
+### Implementation Steps
+1) `.env.example`
+   - Add `COMFYUI_HOSTNAME=comfyui.yourdomain.com`
+2) Wizard
+   - Add `comfyui` to selectable services list
+3) docker-compose
+   - Add `comfyui` service (image, port 8188, volumes: `comfyui_data:/data` or image-appropriate paths)
+   - Add `comfyui_data:` to top-level volumes
+   - Optional GPU: add NVIDIA device reservations when available
+4) Caddy
+   - Add site for `{$COMFYUI_HOSTNAME}` with `reverse_proxy comfyui:8188`
+5) Final report
+   - Print ComfyUI URL when profile active
+6) Secrets script
+   - Generate/populate `COMFYUI_HOSTNAME` similar to other hostnames
+
+### Potential Challenges
+- Large model storage footprint; ensure persistent volume and document where to place models
+- GPU optionality: only enable when NVIDIA toolkit exists; keep CPU default to avoid install friction
+- WebSockets: Caddy generally handles WS automatically; verify UI works via proxy
+
+### Technology Validation Checkpoints
+- [ ] Confirm maintained image name and tag
+- [ ] Verify port 8188 and container paths for volumes (models/custom_nodes)
+- [ ] Validate Caddy reverse proxy works (incl. websockets)
+- [ ] Optional: Validate GPU flags on a host with NVIDIA toolkit
+
+### Testing Strategy
+- Start only Caddy + ComfyUI with profile enabled
+- Access `https://COMFYUI_HOSTNAME` and verify UI loads and basic workflow runs
+- Confirm persistence of uploads/outputs in `comfyui_data`
+
+### Next Mode Recommendation
+- Implement Mode (no creative phase required)
+
+### Reflection Status (ComfyUI)
+- [x] Implementation thoroughly reviewed
+- [x] Successes documented
+- [x] Challenges and solutions analyzed
+- [x] Lessons Learned documented
+- [x] Process/Technical improvements identified
+- [x] reflection-comfyui-integration.md created
+- [x] tasks.md updated with reflection status
+
+### Reflection Highlights (ComfyUI)
+- **What Went Well**: Minimal changes following established patterns (profiles, Caddy, wizard, README, final report); compose validated successfully.
+- **Challenges**: Lack of a clearly “official” image; differing volume paths across images; optional GPU support trade-offs.
+- **Lessons Learned**: Default to CPU for broad compatibility; keep image choice abstract to allow swapping; add validation checklist for volumes and websockets.
+- **Improvements**: Consider adding a GPU sub-profile and documenting model storage locations; later evaluate swapping to a more authoritative image with stable volume conventions.
