Vibe Workflow is a free, open-source node-based AI workflow builder — the self-hostable alternative to Weavy AI, Freepik Spaces, Krea Nodes, and FloraFauna AI. Designed around "Artistic Intelligence," it gives creators and developers a visual, modular pipeline editor for designing, editing, and composing AI-generated images and video — with no vendor lock-in. Read the full story: I built Open Weavy because paid AI creative tools were getting ridiculously expensive.
🚀 Prefer a hosted version? Try Vibe Workflow instantly at muapi.ai/workflow — fully managed, with API and embed support to plug node-based AI workflows directly into your own platform. See Hosted Version below.
Looking for a Weavy AI alternative? A Krea Nodes alternative? A Freepik Spaces alternative? A FloraFauna AI alternative? Vibe Workflow is fully open-source, self-hostable, and free — with the same node-based visual editor you know and love.
Don't want to self-host? A fully managed, hosted version of Vibe Workflow is available at muapi.ai/workflow — zero setup, ready to use in the browser.
The hosted version also ships with: - API support — programmatically run workflows and integrate generative pipelines into your own apps and backends. - Embed support — drop the workflow builder directly into your own platform or product via an embeddable widget, so your users get a node-based AI editor without leaving your UI.
Use the hosted version if you want to skip infra and add node-based AI workflows to your own platform in minutes.

Paid AI creative tools have become ridiculously expensive. Vibe Workflow bridges the gap between complex generative AI capabilities and intuitive visual design. Where tools like Weavy AI and Krea Nodes offer powerful node-based systems behind paywalls, Vibe Workflow gives you the same power — open-source, flexible, and extendable:
Vibe-Workflow/
├── client/ # Next.js frontend application
├── packages/
│ └── workflow-builder/ # Shared UI library — the core node editor
└── server/ # FastAPI backend
For local development: - Node.js (v20+) - Python (v3.10+) - npm (v7+ for workspaces support)
Or use Docker (see Running with Docker).
Clone the repository:
bash
git clone https://github.com/samuraigpt/vibe-workflow.git
cd vibe-workflow
Install all dependencies (root directory):
bash
npm install
This installs dependencies for the client, the workflow-builder library, and links them via npm workspaces.
Vibe Workflow uses MuAPI (Vadoo AI) for generative AI capabilities. You need an API key.
Get your API Key from muapi.ai — sign up, navigate to API Keys, generate a key.
Configure the Backend:
bash
cd server
cp .env.example .env
# Open .env and set:
# MU_API_KEY=your_actual_api_key_here
Frontend (Next.js):
npm run dev:app
# Available at http://localhost:3000
Backend (FastAPI):
cd server
python -m venv venv
source venv/bin/activate # Windows: venv\Scripts\activate
pip install -r requirements.txt
# Run the server
uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
The easiest way to run Vibe Workflow is with Docker Compose.
Configure environment:
bash
cp .env.example .env
Edit .env and add your MuAPI key:
bash
MU_API_KEY=your_actual_api_key_here
Start all services:
bash
docker compose up --build
Access the application:
| Service | Image | Port |
|---|---|---|
| client | Node.js 24 Alpine | 3000 |
| server | Python 3.13 | 8000 |
docker compose down
bash
npm run build:libbash
npm run dev:appWeavy AI is a proprietary node-based creative AI platform. Vibe Workflow is its open-source equivalent — same visual workflow paradigm, fully self-hostable, MIT licensed, with no subscription fees.
Krea Nodes offers a powerful real-time generative canvas. Vibe Workflow brings a comparable node-based editor that is open-source, customizable, and extendable with any AI backend.
Freepik Spaces is a cloud-based AI creative suite integrated with Freepik's asset library. Vibe Workflow provides the workflow and pipeline layer as open-source infrastructure you control, with no asset-library lock-in.
FloraFauna AI offers a creative node canvas for generative media. Vibe Workflow replicates and extends that concept in an open-source, self-hosted package with full extensibility.
