Peacasso
Free open-source desktop UI for generating AI art with diffusion models on your own GPU.
Peacasso is worth installing if your goal is to see and touch a diffusion pipeline rather than just consume its output. The React Flow node canvas with minimap and keyboard node handling makes the pipeline inspectable, the advanced prompt controls keep tuning next to the prompt, and the built-in sample prompts kill the blank-page problem. It runs on your own GPU, so prompts and images stay local and cost nothing per render. Against that: the site labels it Beta, feedback goes through GitHub rather than a support desk, and it is a single-user local app with no shared workspace. If you want a polished hosted product, use a hosted image generator instead; if you have a GPU and want to learn,

Skip Peacasso if you need a shared team workspace or a hosted app you can open on any machine without a GPU, since everything here runs locally as a single-user Beta tool.
Peacasso is free and open source at $0, with no per-generation charge — the real cost is the GPU you run it on. Compared with hosted image generators that bill per render or per seat, it fits individual hobbyists, students and educators who already own capable hardware; it does not fit teams that would need to buy or rent GPUs to use it.
In short
Peacasso — Free open-source desktop UI for generating AI art with diffusion models on your own GPU. Best for Hobbyists exploring diffusion models, Artists learning how generation pipelines are assembled, Educators demonstrating AI image workflows. Free to use.
What is Peacasso?
Peacasso — Free open-source desktop UI for generating AI art with diffusion models on your own GPU. Best for Hobbyists exploring diffusion models, Artists learning how generation pipelines are assembled, Educators demonstrating AI image workflows. Free to use.
Peacasso is a free, open-source UI for generating art with diffusion models on your own machine. You write a prompt, optionally preview it with suggested additions, adjust advanced prompt controls, and generate a result. If you do not have a prompt in mind, the homepage ships a sample library — painterly leprechaun portrait, side-profile warrior chief, a Wyatt Earp portrait in the style of Eugene de Blaas and Ross Tran, a cinematic robot bust, a Victorian amphitheater of sand — that you can load with one click. The workflow area is built on React Flow, so generation steps appear as nodes on a canvas with a minimap you can pan; keyboard shortcuts let you select a node with enter or space, nudge it with the arrow keys, and delete it with delete or escape. The interface has a toggleable dark mode and adapts to smaller screens. Everything runs locally on a compatible GPU, so prompts and outputs stay on your own hardware and you do not pay per generation. It is labelled Beta and developed in the open on GitHub, with feedback routed through the repository. It suits hobbyists, artists learning how diffusion pipelines are assembled, and educators who want a whiteboard for generation settings — not teams needing shared workspaces or hosted storage.

Models under the hood
as of 2026-11-08
Limitations
- Peacasso's own page labels it Beta and asks for feedback, so expect rough edges.
- It runs locally on your own GPU, so generation speed and what you can realistically attempt depend on your hardware, and a weak card makes the tool impractical.
- Support is the GitHub repository rather than a support desk, so you rely on issues and community response.
- The reachable evidence is a single page plus a blog index, so treat claims about extensibility, API access or release cadence as unverified.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Peacasso actually fits — and what changes day-one when you adopt it.
Load the leprechaun portrait sample prompt, tweak the advanced prompt controls, and generate repeatedly to see what each setting does.
Outcome: You learn which control changes actually move the output without spending money per render, and your images stay on your own disk.
Lay the generation steps out as React Flow nodes, connect them by drag-and-drop, and use the minimap and keyboard shortcuts to rearrange the graph.
Outcome: You end up with a reusable visual arrangement of your generation process instead of a prompt you retype from memory.
Project the node canvas and the sample prompt library, then walk through how a verbose prompt like the 50mm warrior-chief portrait is composed.
Outcome: Students see both the prompt anatomy and the pipeline structure in one screen, which is hard to do with a black-box hosted generator.
Use cases
- Start from a built-in sample prompt such as the robot bust or the Victorian amphitheater and iterate from there
- Adjust advanced prompt controls and watch how each change shifts the output
- Lay out a generation pipeline as nodes and reuse the arrangement instead of retyping prompts
- Teach how a diffusion pipeline is assembled using the node canvas as a shared whiteboard
- Prototype visual concepts locally without paying per generation
- Keep prompts and generated images on your own GPU-backed machine
Setup time & first value
How long it actually takes to get something useful out of Peacasso — broken out by persona, not the marketing-page minute.
Hobbyists with a compatible GPU and GitHub access: expect an afternoon to install the project, get a first image out, and find your way around the node canvas. Educators planning to demo: budget extra time to rehearse the canvas and keyboard shortcuts before class. Without a working GPU, setup stops at the hardware.
