Install, platforms & data +
- platforms
- desktopwebself-hostedone-click install
- install
- Windows or macOS desktop installer, Windows portable archive, or manual Python install on Windows, macOS, or Linux
- setup
- A compatible GPU, enough VRAM and disk for multi-gigabyte models, and a working model/workflow must be chosen before useful output appears
- engines
- Local and downloadable image, video, audio, 3D, and text models including Stable Diffusion/SDXL/SD3.5, FLUX, Wan, LTX-Video, HunyuanVideo, CogVideoX, and Mochi; optional API nodes connect to hosted providers

InvokeAI
open sourceApache-2.0Local or hosted28kaug 2026Multiple local models, strong controls and an organized gallery; private means actually staying on your machine.
The catch vs Mage.SpaceIt offers a superior local canvas and organization, but no included cloud fleet or instantly available hosted community models.
Install, platforms & data +
- platforms
- desktopwebself-hostedone-click install
- install
- Install through Invoke's launcher on Windows, macOS, or Linux, or deploy the documented Docker setup
- setup
- The launcher is straightforward, but the user still needs a compatible GPU, a large model download, and sometimes a gated-model login or provider API key
- engines
- Local models including Stable Diffusion, SDXL, SD3.5, FLUX, CogView, Z-Image, Krea, Anima, Qwen Image, Ideogram, and segmentation models; selected hosted models such as GPT Image, Gemini/Nano Banana, and Wan use API credentials
- your data
- Models, images, boards, canvas state, prompts, metadata, and a SQLite database live in the local Invoke data directory; API-backed nodes send only the selected prompt and image context to their provider
- checked

Krita AI Diffusion
open sourceGPL-3.0Local or hosted10kjun 2026Krita with a local diffusion engine: layers, masks, generated pixels and no gallery watching you.
The catch vs Mage.SpaceIt is a real editor, but requires Krita plus a backend and lacks Mage.Space's no-install, feed-like model discovery.
Install, platforms & data +
- platforms
- desktopself-hostedone-click install
- install
- Install Krita, import the plugin ZIP through Krita's Python-plugin importer, then connect a managed/local ComfyUI backend or the optional cloud service
- setup
- Local use requires Krita, the plugin, a multi-gigabyte ComfyUI model bundle, and enough GPU memory; the easier cloud path requires an account
- engines
- ComfyUI-based Stable Diffusion, SDXL, FLUX, ControlNet, IP-Adapter, inpainting, upscaling, and segmentation workflows, plus models offered by the optional Interstice cloud
- your data
- The working image remains a local Krita document with layers and masks; local backends keep models and outputs on the machine, while cloud mode sends the prompt and relevant image/layer data
- checked

SwarmUI
open sourceMITSelf-host4.4kaug 2026A private multi-model generator with a simple tab up front and serious controls behind it.
The catch vs Mage.SpaceIt is flexible and private after setup, but model downloads and GPU management replace Mage.Space's hosted convenience.
Install, platforms & data +
- platforms
- desktopwebself-hostedone-click install
- install
- Run the Windows installer script, the Linux launch script, or install .NET/Python/Homebrew prerequisites and run launch-macos.sh on macOS; Docker is optional
- setup
- The backend and models still have to be downloaded, and non-Windows installs require command-line prerequisites such as .NET, Python, and Git
- engines
- Uses ComfyUI as its main backend for Stable Diffusion, SDXL, FLUX, Wan, LTX, MiniMax, ACE-Step, and other image/video/audio workflows; an Automatic1111-compatible backend is optional
- your data
- Configuration, users, models, workflows, generated media, and history live in the local SwarmUI installation and configured model/output directories
- checked

SDAI
open sourceAGPL-3.0Local or hosted1.2kaug 2026Mobile generation through local models, your own server or AI Horde; privacy depends on which route you choose.
The catch vs Mage.SpacePrivacy depends on the selected backend, and configuring that backend is much less immediate than signing into Mage.Space.
Install, platforms & data +
- platforms
- mobileone-click install
- install
- Install the Android or iOS app from an app store/F-Droid, or sideload the published APK; then select a local, self-hosted, or hosted provider
- setup
- The first screen is provider configuration: a non-expert must supply a server URL/API key or obtain and configure an experimental local model
- engines
- Automatic1111 and SwarmUI servers, AI Horde, Hugging Face, OpenAI Images, Stability, FAL, ArliAI, and experimental on-device Android ONNX/MediaPipe/stable-diffusion.cpp or Apple Core ML/MLX backends

RuinedFooocus
open sourceGPL-3.0Local680jul 2026A low-friction local generator with styles, inpainting and reruns; Windows and Linux only.
The catch vs Mage.SpaceIt is easier than most local UIs, but runs only on Windows and Linux and cannot match Mage.Space's hosted model breadth and anywhere access.
Install, platforms & data +
- platforms
- desktopwebself-hostedone-click install
- install
- Extract the Windows release and run its launcher, or clone the repository and create the documented Python environment on Linux
- setup
- Windows needs a current 7-Zip extraction and a multi-gigabyte base-model download; Linux requires a manual Python environment, and macOS is not an official target
- engines
- Prompt-first local SDXL-compatible checkpoints with styles, LoRAs, inpainting, image prompting, and related Fooocus workflows
- your data
- Checkpoints, LoRAs, settings, presets, outputs, and image metadata live in local folders; generated PNG files can retain generation parameters
- checked

Install, platforms & data +
- platforms
- desktopmobileone-click install
- install
- Install the signed app from Apple's App Store on macOS, iPhone, or iPad
- setup
- Apple hardware is required, and the first model download is large; older devices can be slow or memory-limited
- engines
- Runs supported Stable Diffusion, SDXL, FLUX, and video models locally, including imported checkpoints and LoRAs; optional cloud compute can offload generation
- your data
- Projects, models, history, and generated media live in the app sandbox; on macOS model files are under the app container, while cloud offload sends prompts and media for processing

Easy Diffusion
freeproprietary, freeLocalA cross-platform local generator with queues, controls and custom models; no hosted convenience, no hosted bill.
The catch vs Mage.SpaceIt provides a familiar local form, but the user must maintain models and compute rather than choosing from Mage.Space's hosted catalog.
Install, platforms & data +
- platforms
- desktopwebself-hostedone-click install
- install
- Run the Windows installer, or extract the Linux/macOS package and start it with ./start.sh
- setup
- Windows may show SmartScreen, macOS/Linux use a terminal launcher, and the first runtime plus model download can consume roughly tens of gigabytes
- engines
- Local diffusion models including Stable Diffusion variants, FLUX, Z-Image, ERNIE, Lumina, Anima, and supported quantized/custom checkpoints
- your data
- Models, settings, prompts, and generated images remain in the local installation and output directories; the app contacts package/model hosts for dependencies and downloads but says it does not send prompts or images for analytics

Frequently Asked Questions
Direct answers · Mage.Space open-source replacements
What is the best free alternative to Mage.Space?+
The top free alternative to Mage.Space is ComfyUI (open source, GPL-3.0). The broadest local model support in the least browser-service-shaped interface imaginable. Other popular Mage.Space replacements include InvokeAI, Krita AI Diffusion, SwarmUI.
Can I self-host a free replacement for Mage.Space?+
Yes. Of the 8 free alternatives to Mage.Space, 8 can be self-hosted on your own server or local machine: ComfyUI (GPL-3.0), InvokeAI (Apache-2.0), Krita AI Diffusion (GPL-3.0), SwarmUI (MIT), SDAI (AGPL-3.0), RuinedFooocus (GPL-3.0), Draw Things (GPL-3.0), Easy Diffusion (proprietary, free).
Should I vibe-code or build my own Mage.Space clone from scratch?+
Our build verdict for Mage.Space is NOT REALLY (use a free alternative, save the tokens). Do not mistake the interface for the product. Mage.Space's durable value is proprietary model, inference, which a solo one-shot build cannot reproduce responsibly. The prompt therefore builds only the closest honest personal consolation tool.
What is the catch when switching from Mage.Space to ComfyUI?+
It supports more models, but loses Mage.Space's zero-install hosted GPU pool, account-based private gallery, and simple model browsing.
