Open Higgsfield AI — Open-Source Alternative to Higgsfield AI

The free, open-source alternative to Higgsfield AI. Generate AI images and videos using 200+ state-of-the-art models — without the closed ecosystem or subscription fees.

⬇️ Download Desktop App

One-click installers — no Node.js or terminal required.

Platform	Download
macOS Apple Silicon (M1/M2/M3/M4)	Open Higgsfield AI-1.0.0-arm64.dmg
macOS Intel (x64)	Open Higgsfield AI-1.0.0.dmg
Windows (x64 + ARM64)	Open Higgsfield AI Setup 1.0.0.exe

All releases: github.com/Anil-matcha/Open-Higgsfield-AI/releases

macOS Installation Guide

Because the app is not notarized by Apple, macOS Gatekeeper will block it on first launch. Follow these steps:

Step 1 — Mount the DMG and drag the app to /Applications

Step 2 — Open Terminal and run:

`1`	`xattr -cr "/Applications/Open Higgsfield AI.app"`

Step 3 — Right-click the app in /Applications → click Open → click Open again on the dialog

You only need to do this once. After that, the app opens normally.

Alternative (no Terminal):

Try to open the app — macOS will block it
Go to System Settings → Privacy & Security
Scroll down to find “Open Higgsfield AI was blocked”
Click Open Anyway → Open

Windows Installation — SmartScreen warning fix

Windows SmartScreen may show a warning because the installer is not code-signed:

Click More info on the SmartScreen dialog
Click Run anyway

The app will install silently to %LocalAppData% with a Start Menu shortcut.

Open Higgsfield AI is an open-source AI image, video, cinema, and lip sync studio that brings Higgsfield-style creative workflows to everyone. Powered by Muapi.ai, it supports text-to-image, image-to-image, text-to-video, image-to-video, and audio-driven lip sync generation across models like Flux, Nano Banana, Midjourney, Kling, Sora, Veo, Seedream, Infinite Talk, LTX Lipsync, Wan 2.2, and more — all from a sleek, modern interface you can self-host and customize.

Why Open Higgsfield AI instead of Higgsfield AI?

Free & open-source — no subscription, no vendor lock-in
Self-hosted — your data stays on your machine
200+ models — text-to-image, image-to-image, text-to-video, image-to-video, lip sync
Multi-image input — feed up to 14 reference images into compatible models
Lip Sync Studio — animate portraits or sync lips to any audio with 9 dedicated models
Extensible — add your own models, modify the UI, build on top of it

For a deep dive into the technical architecture and the philosophy behind the “Infinite Budget” cinema workflow, see our comprehensive guide and roadmap.

✨ Features

Image Studio — Generate images from text prompts (50+ text-to-image models) or transform existing images (55+ image-to-image models). Switches model set automatically based on whether a reference image is provided. Quality and resolution controls visible for models that support them.
Multi-Image Input — Upload up to 14 reference images for compatible edit models (Nano Banana 2 Edit, Flux Kontext Dev, GPT-4o Edit, and more). Multi-select picker with order badges, batch upload, and a “Use Selected” confirmation flow.
Video Studio — Generate videos from text prompts (40+ text-to-video models) or animate a start-frame image (60+ image-to-video models). Same intelligent mode switching as Image Studio.

🏗️ Architecture

The app is a Next.js monorepo with a shared packages/studio component library.

├── tailwind.config.js
└── package.json                # workspaces: ["packages/studio"]

The packages/studio library is also consumed by the hosted version on muapi.ai — model updates made in packages/studio/src/models.js apply to both the self-hosted app and the hosted version automatically.

🔌 API Integration

The app communicates with Muapi.ai using a two-step pattern:

Submit — POST /api/v1/{model-endpoint} with prompt and parameters
Poll — GET /api/v1/predictions/{request_id}/result until status is completed

Authentication uses the x-api-key header. During development, a Vite proxy handles CORS by routing /api requests to https://api.muapi.ai.

File uploads use POST /api/v1/upload_file (multipart/form-data) and return a hosted URL that is passed to image-conditioned models. For multi-image models the full images_list array is forwarded to the API in one request.

Lip sync jobs use the same two-step pattern: a dedicated processLipSync() method accepts image_url or video_url alongside audio_url, dispatches to the model’s endpoint, and polls until the output video URL is available.
