Self-hosting — one command, bundled ComfyUI workflows, gateway modes

docker compose up runs the whole app; --profile gpu adds a ComfyUI sidecar. Wan 2.2 (I2V, first+last frame, GGUF) and LTX-2 graphs ship in selfhost/comfyui and are chosen per job. Admin → Gateway sets Official / Custom / Hybrid.

Needs: Docker for the container path; SELFHOST_ENDPOINT for the self-hosted model path. Without it this feature reports that it is unavailable rather than failing silently.

### One command

docker compose up -d builds and runs the app on port 3000 with SQLite in a named volume and FFmpeg installed, so the local processing tools work out of the box. Copy .env.example to .env first and fill in whatever keys you have; nothing is required to boot.

docker compose --profile gpu up -d adds a ComfyUI sidecar on port 8188 (needs the NVIDIA container toolkit) and mounts ./models into it. Point SELFHOST_ENDPOINT at it.

### Bundled workflows

Five ComfyUI graphs ship under selfhost/comfyui/: Wan 2.2 image-to-video (fp8), Wan 2.2 first+last frame, Wan 2.2 GGUF Q4 for 12 GB cards, LTX-2 text-to-video and image-to-video. For a video job the adapter picks one — first+last frame → FLF, one frame → I2V (the GGUF graph when SELFHOST_VRAM_GB is under 24), text only → LTX-2 — fills the placeholders with the job's prompt, seed, size and frames, and sends the bound graph alongside its generic body. Set SELFHOST_WORKFLOW=<id> to force one. Drop your own .json in the folder to add one; the admin page lists what it found and which model files each needs.

### Gateway modes (Admin → Gateway)

  • Official — cloud providers only; a self-hosted endpoint is ignored even if set.
  • Custom — self-hosted only; cloud keys are ignored. Refuses to switch on until SELFHOST_ENDPOINT is set, because otherwise every render would be refused.
  • Hybrid — self-hosted preferred where it can do the job, cloud for the rest.

It is a hard gate in the router, so Custom means custom: a render that cannot go to your endpoint fails with the reason rather than quietly going to the cloud. Local FFmpeg passes (upscale, HDR, social cuts) run in every mode.

Director World — 360 panoramas, Gaussian splats and voxel sets

Turn one frame into a set: a 360° panorama, a Gaussian-splat reconstruction or a voxel scene. Lock camera positions, capture frames as a shot's pose reference, restyle a voxel set with one word.

Analyze — sketch detection, reverse prompt, pen marks, shot analysis, audio separation

Pixel-level tools that cost nothing: is this a sketch or coloured, what is its palette, where are the red/green/blue/yellow pen marks, where are the cuts in a video. Reverse prompting uses a vision model when configured. Audio separation needs the self-hosted endpoint.
