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

🔌 API Integration

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

  1. SubmitPOST /api/v1/{model-endpoint} with prompt and parameters
  2. PollGET /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.

🎨 Supported Models

Model Endpoint Resolution Options
Nano Banana nano-banana
Nano Banana Pro nano-banana-pro up to 4K (Cinema Studio)
Flux Schnell flux-schnell-image
