The fastest way to get more from Invoke AI

Invoke is what serious Stable Diffusion users graduate to. Instead of one text box, you get a node-based Workflow canvas: chain models, controlnets, inpainting, and face fixers into repeatable pipelines. It's open-source and self-hostable, so your data and models never leave your machine. There's also a hosted tier if you don't want to run GPUs.

Who it's for: Artists, concept designers, and studios who need reproducible, controllable pipelines and model ownership.

Key features

Workflows Node-based Workflows

Build visual pipelines linking models, controlnets, and post-processing into reusable, shareable graphs.

Control Precision control

Regional prompting, inpainting, outpainting, and ControlNet guidance for exact compositions.

Self-host Self-host or cloud

Run free on your own hardware, or use Invoke's hosted tier — your choice.

Open Open source & auditable

Apache 2.0. Fork it, extend it, own your assets and models.

The honest take

✓ What works

  • Unmatched control via node-based workflows
  • Fully open-source and self-hostable — data stays yours
  • Great for reproducible, production pipelines
  • Active community and frequent releases
  • Free to run if you have the hardware

✗ What doesn't

  • Steeper learning curve than Midjourney
  • You supply and manage your own models/GPUs (self-host)
  • UI less polished than commercial rivals
  • No phone app; desktop/GPU focus

Verdict

Invoke is the pro's Stable Diffusion cockpit. If you want Midjourney simplicity, look elsewhere; if you want control, ownership, and repeatable pipelines, it's the best open-source option. Free to self-host.
