Midjourney alternatives: 4 open-source picks
Midjourney costs $10/mo — $120 a year. These 4 alternatives replace it for $0, led by ComfyUI, InvokeAI and SwarmUI. All 4 are open source. License, stars and last commit checked by hand on 2026-08-10. No trials, no crippled tiers.
Can produce superb images with current models, provided you are willing to become the workflow designer.
licenseGPL-3.0
runson your machine
installDesktop app, Windows portable archive or Python source installation
enginesStable Diffusion, SDXL, SD3 and SD3.5, FLUX, Qwen Image, Hunyuan, Wan and many other local or custom-node backends
dataModel weights under the local models directories, outputs on disk, and reproducible workflows as JSON or embedded PNG metadata
the catch vs MidjourneyYou must choose and install models and design workflows yourself, and you lose Midjourney's unusually consistent house aesthetic and prompt simplicity.
setupLarge model downloads and a compatible GPU; custom nodes add dependency, security and workflow complexity

A polished local studio for strong open image models; better editing, less instant house style.
licenseApache-2.0
runson your machine
installInstall the Invoke launcher, then launch its local web application
enginesStable Diffusion 1.5, 2, XL and 3.5, FLUX, Qwen Image and supported API-backed image models
dataModel weights, application database, gallery boards, images and generation metadata live on the local instance
the catch vs MidjourneyIt is a better-controlled studio but requires model management and more decisions instead of Midjourney's fast, consistent house style.
setupA compatible GPU, launcher setup and large model downloads; API-backed models also need keys
facts verified 2026-08-10
A prompt-first local UI for current image models; you supply the model and GPU instead of renting the aesthetic.
licenseMIT
runson your machine
installRun the Windows install batch file or Linux or macOS install script
enginesComfyUI-backed local models including Stable Diffusion, FLUX and newer image or video models, plus supported remote backends
dataModels, configuration, generation history and output images live in the local SwarmUI installation
the catch vs MidjourneyIt gives you control instead of a house model, so you supply the GPU, models and aesthetic judgment that Midjourney hides.
setupA compatible GPU and model downloads; the application is still labeled beta and first launch installs its backend
facts verified 2026-08-10
The closest thing here to prompt-and-go; its defaults are friendly, its model stack less fashionable.
licenseGPL-3.0
runson your machine
installDownload the Windows archive and run run.bat, or install a Python virtual environment on Linux
enginesSDXL and compatible local checkpoints, including newer FLUX, Krea and other supported model families, plus LoRAs and styles
dataModels and outputs are stored in local application folders; generation settings can be embedded in image metadata
the catch vs MidjourneyIts defaults are approachable, but model quality and aesthetic consistency remain less predictable than Midjourney's curated service.
setupLarge automatic model downloads and a capable GPU; Linux installation is source and virtual-environment based
