§ 02OPEN-SOURCE REPLACEMENTS5

Self-hosted, free, or freemium tools that cover the same workflow. Every entry is real software with a public repo and an active community.

Stable Diffusion WebUI (Automatic1111)FREE / OSS145k★AGPL-3.0

Default Midjourney replacement if you have a GPU. Largest community + extension library.

  • Most-used SD frontend
  • Massive extension ecosystem
  • img2img, ControlNet, LoRA training
git clone, run webui-user.bat / webui.sh
! caveat: Needs 8GB+ VRAM for usable speeds. Setup is fiddly.
ComfyUIFREE / OSS65k★GPL-3.0

When you want full control over the diffusion pipeline. Power-user choice.

  • Node-based image/video pipeline
  • SDXL, Flux, video diffusion models
  • Reproducible workflows you can share as JSON
git clone + Python deps
! caveat: Steep learning curve vs A1111.
FLUX.2 [klein] 4BFREE / OSSApache-2.0

Fast, fully-open (Apache-2.0) Midjourney alternative you can run locally. The 4B 'klein' is the commercially-usable variant.

  • 4B rectified-flow transformer from Black Forest Labs
  • Text-to-image + multi-reference editing in one model
  • Sub-second generation on consumer GPUs
Download FLUX.2-klein-4B from HuggingFace; run in ComfyUI or via github.com/black-forest-labs/flux2
! caveat: Only the 4B klein is Apache-2.0 - the 9B klein and FLUX.2 [dev] are non-commercial. Needs ~13GB VRAM (RTX 3090/4070+).
FooocusFREE / OSS42k★GPL-3.0

If you want Midjourney's simplicity without ComfyUI's complexity.

  • Midjourney-feel UX (one prompt, presets)
  • Built-in style library
  • Minimal config - just run
Download zip, run run.bat / run.sh
! caveat: Less customizable than A1111/ComfyUI.
InvokeAIFREE / OSS24k★Apache-2.0

Cleanest UI in the SD ecosystem. Best for design-pipeline use.

  • Polished web UI
  • Canvas/inpainting workflow
  • Studio-grade install experience
Installer .exe / .pkg / launcher script
! caveat: Needs 8GB+ VRAM. Smaller extension ecosystem than A1111/ComfyUI.
