Replace Midjourney with ComfyUI / Invoke
The best open-source alternative to Midjourney is ComfyUI or Invoke, self-hosted on Railway. Images you generate. ComfyUI is GPL; Invoke is Apache-2.0 — Midjourney without the render in someone else's Discord.
Estimated save $1,200 a year.

How Midjourney compares
| Midjourney | ComfyUI / Invoke | |
|---|---|---|
| Pricing model | Hosted subscription | Open-source or fair-code license; you pay the host |
| Hosting | Vendor cloud | Self-hosted on Railway or any VPS |
| Rough monthly cost | Public list price not verified this run | Hosting only — no SaaS seat meter in this repo |
FAQ
- Is it free?
- The ComfyUI / Invoke licenses are open source or fair-code. You still pay hosting (Railway or any VPS) and any APIs the stack calls. There is no Midjourney seat or task bill on this path.
- Can I migrate from Midjourney?
- Yes. Start with the workflows or data you actually use, then cut over. The ComfyUI / Invoke stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old Midjourney links until they expire.
- How do I deploy it?
- Open the ComfyUI / Invoke stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). Placeholder: ComfyUI or Invoke plus a volume for models. A GPU helps; CPU is slow. No one-click template in this repo yet — Start on Railway. Chat UIs stay on /stacks/open-webui-litellm.
- What does this replace?
- Midjourney. The published small-team estimate on this stack is $1,200 a year.
