Open Higgsfield AI — Open-Source Alternative to Higgsfield AI

The free, open-source alternative to Higgsfield AI. Generate AI images and cinematic shots using 20+ state-of-the-art models — without the closed ecosystem or subscription fees.

Open Higgsfield AI is an open-source AI image and cinema studio that brings Higgsfield-style creative workflows to everyone. Powered by Muapi.ai, it supports models like Flux Schnell, Flux Dev, SDXL, Ideogram, Midjourney, 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
• 20+ models — access more AI models than any single closed platform
• Extensible — add your own models, modify the UI, build on top of it

✨ Features

• Cinema Studio — Higgsfield AI-style interface for photorealistic cinematic shots with pro camera controls (Lens, Focal Length, Aperture)
• Multi-Model Support — Switch between 20+ AI image generation models (Flux, Nano Banana, Ideogram, Midjourney, SDXL, and more)
• Smart Controls — Dynamic aspect ratio and resolution pickers that adapt to each model's capabilities
• Generation History — Browse, revisit, and download all your past generations (persisted in browser storage). Now with a persistent sidebar in Cinema Studio.
• Image Download — One-click download of generated images in full resolution (up to 4K)
• API Key Management — Secure API key storage in browser localStorage (never sent to any server except Muapi)
• Responsive Design — Works seamlessly on desktop and mobile with dark glassmorphism UI

🚀 Quick Start

Prerequisites

• Node.js (v18+)
• A Muapi.ai API key

Setup

# Clone the repository
git clone https://github.com/Anil-matcha/Open-Higgsfield-AI.git
cd Open-Higgsfield-AI

# Install dependencies
npm install

# Start the development server
npm run dev

Open http://localhost:5173 in your browser. You'll be prompted to enter your Muapi API key on first use.

Production Build

npm run build
npm run preview

🔌 API Integration

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

1. Submit — POST /api/v1/{model-endpoint} with prompt and parameters
2. 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.

🤔 How is this different from Higgsfield AI?

Higgsfield AI is a proprietary AI video and image generation platform. Open Higgsfield AI is a community-driven, open-source alternative that provides similar creative capabilities without the closed ecosystem:

	Higgsfield AI	Open Higgsfield AI
Cost	Subscription-based	Free (open-source)
Models	Proprietary	20+ open & commercial models
Self-hosting	No	Yes
Customizable	No	Fully hackable
Data privacy	Cloud-based	Your data stays local
Source code	Closed	MIT licensed
