Invoke AI
Free, open-source, self-hosted AI image generation engine with a Unified Canvas and node-based workflows.
If you own a capable GPU and want your image pipeline to stay yours, Invoke AI is the strongest free pick in this category. The Unified Canvas does inpainting, outpainting, brush work, and compositing in one workspace, and the node workflow editor turns lucky prompts into repeatable pipelines — neither is something Midjourney offers. Apache 2.0 licensing means commercial use without per-seat fees. But if you want a managed cloud service with SSO and role-based access, look at Leonardo or Adobe Firefly instead; Invoke expects you to run and update the software yourself.

Skip Invoke AI if you want a browser-based tool with no install, or if your team needs managed cloud hosting, SSO, and role-based access control rather than software you run and update on your own GPU hardware.
The software is free, but a capable GPU is the real entry cost — a machine that runs Flux.2 and SD 3.5 Large comfortably is a hardware purchase, not a subscription.
At $0 under Apache 2.0, Invoke AI undercuts every subscription image platform: Midjourney, Adobe Firefly, and Leonardo all charge monthly per seat, while Invoke charges nothing and imposes no per-seat limit. The trade is capital and time — you supply a capable GPU and handle installs and updates yourself. Studios running several artists on one workstation come out far ahead; solo users without a GPU may spend more on hardware than a year of hosted subscriptions would cost.

About Invoke AI
Invoke AI is an Apache 2.0 licensed, free creative engine for AI image generation that you install and run on your own hardware. It launches a locally hosted web server with a React UI, so prompts, models, and outputs stay on your machine. The project's GitHub repository shows 28.3k stars and 19,177 commits, and the vendor states it 'serves as the foundation for multiple commercial products.' The centerpiece is the Unified Canvas, a single workspace covering text-to-image, image-to-image, inpainting, outpainting, brush tools, and compositing, so you can build on sketches, photography, and renders instead of discarding each prompt. Alongside it sits a node-based workflow editor for building, saving, and sharing repeatable generation pipelines. Model coverage is broad: SD 1.5, SD 2.0, SDXL, SD 3.5 Medium and Large, CogView 4, the Flux.1 family (Dev, Schnell, Kontext, Krea, Redux, Fill), Flux.2 Dev plus Klein 4B and 9B, Z-Image Turbo and Base, Krea 2 Turbo and Raw, Anima, Qwen Image and Edit, Ideogram 4, and ERNIE-Image, with API-only models including Nano Banana, GPT Image, and Wan. It loads ckpt, diffusers, and some gguf formats, and includes upscaling tools with embedding and model managers. Boards and galleries organize assets, images drag onto any image-based UI element, and SAM/SAM2 segmentation gives precise selection for targeted edits. The trade-off is real: you need a capable GPU, and installation, model downloads, and dependency updates are yours to maintain.
Behind the Verdict
Invoke AI is the rare open-source image tool that behaves like production software rather than a demo. The Unified Canvas is the reason most people stay: inpainting, outpainting, brush tools, and compositing live in one canvas, so a retouch, an expansion, and a style pass don't require three separate tools. The node-based workflow editor is the second pillar — you build a generation pipeline once, save it, and share it with collaborators, which is how studios get consistent character and style output instead of re-rolling prompts. Model breadth is genuinely unusual for a self-hosted tool. The vendor's own repository lists SD 1.5, SD 2.0, SDXL, SD 3.5 Medium and Large, CogView 4, the Flux.1 family (Dev, Schnell, Kontext, Krea, Redux, Fill), Flux.2 Dev and Flux.2 Klein 4B/9B, Z-Image Turbo and Base, Krea 2 Turbo and Raw, Anima, Qwen Image and Edit, Ideogram 4, and ERNIE-Image, with Nano Banana, GPT Image, and Wan available as API-only models. It loads ckpt, diffusers, and some gguf formats. SAM and SAM2 segmentation give you pixel-level selection for edits. Boards and galleries keep assets organized with rich metadata so you can recall the exact prompt and settings behind any image. Where it strains: installation is not plug-and-play, a capable NVIDIA GPU or Apple Silicon machine is effectively required, and there's no managed hosting, SSO, or role-based access control. Model downloads and dependency updates are ongoing chores. The node editor in particular rewards patience — newcomers used to a single prompt box will find it heavy. The Apache 2.0 license and the fact that prompts and images never leave your machine are the reasons privacy-sensitive client work and studios with per-seat cost concerns keep choosing it anyway. If those negatives sound like dealbreakers, a hosted competitor will serve you better; if they sound like acceptable costs of ownership, nothing free comes close.

Real-world workflow fit
Concrete scenarios for the personas Invoke AI actually fits — and what changes day-one when you adopt it.
You install the launcher, point Invoke AI at your local Flux.2 and SDXL checkpoints, sketch a silhouette on the Unified Canvas, then use inpainting and outpainting to extend it into a full scene while keeping a client's unreleased character design off any cloud service.
Outcome: A finished composite stays on your machine, and the image metadata lets you recall the exact prompt and settings if the client asks for a variation two weeks later.
You build one node workflow for your game's sprite style, save it, and reuse it across dozens of assets, generating batches of sprites and textures and then using SAM/SAM2 selection to fix edges on individual pieces.
Outcome: Consistent art direction across the asset set without re-rolling prompts each time, and no per-seat fee as your team grows.
You standardize the team on Invoke AI, share node workflows so everyone generates in the same pipeline, and keep boards organized by project for review.
Outcome: Repeatable output at zero licensing cost, with the caveat that installs, GPU provisioning, and updates are your team's responsibility.
Use Cases
- Generate concept art for games and films from text prompts
- Edit and composite images with inpainting and outpainting on a unified canvas
- Build consistent character designs by fine-tuning with LoRA

Ideal for
Digital artists, indie game developers, and studios with their own GPU hardware who want full image generation with no subscription or per-seat fee.
What this tier adds
Free entry point under Apache 2.0 — includes the Unified Canvas, node workflows, and full model support with no paid tier above it.
Where the pricing makes sense
The company stage and team size where Invoke AI's pricing actually pencils out — and where peers do it cheaper.
At $0 under Apache 2.0, Invoke AI undercuts every subscription image platform: Midjourney, Adobe Firefly, and Leonardo all charge monthly per seat, while Invoke charges nothing and imposes no per-seat limit. The trade is capital and time — you supply a capable GPU and handle installs and updates yourself.

Setup time & first value
How long it actually takes to get something useful out of Invoke AI — broken out by persona, not the marketing-page minute.
Expect a meaningful install: download the launcher, then work through the vendor's documentation to get the web server and UI running — an afternoon for a comfortable GPU owner, longer if you hit dependency issues. Model downloads for Flux.2 or SD 3.5 Large add time before your first generation. A non-technical user following the FAQ and Discord for help should budget a full day to reach a first
Switching to or from Invoke AI
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Automatic1111 (Stable Diffusion WebUI): copy your existing ckpt checkpoints into Invoke's model manager, then rebuild your favorite settings as a saved node workflow.
- →From ComfyUI: convert node graphs to Invoke's workflow editor, then keep using the Unified Canvas when you want a direct painting surface instead of a graph.
- →From Midjourney: import your prompt ideas as text-to-image starting points, then use the Unified Canvas to composite and refine results rather than accepting the first output.
- ↗To ComfyUI: export your saved prompt and model settings, then rebuild pipelines as ComfyUI graphs if you want a lighter-weight node-only interface.
- ↗To a hosted service like Leonardo or Adobe Firefly: re-upload your reference images and recreate prompts there if you need managed cloud hosting, SSO, and role-based access control.
