Vibe Workflow — Open-Source Alternative to Weavy AI, Freepik Spaces, Krea Nodes & FloraFauna AI

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.

Sample Workflow UI

Hosted Version

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.

Why Vibe Workflow Over Weavy AI / Krea Nodes / Freepik Spaces / FloraFauna AI?

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:

• Creative Professionals: Build custom AI pipelines for high-volume asset production.
• Studios: Maintain brand consistency across hundreds of generative variations.
• Developers: Extend and integrate generative AI into any existing workflow via API.
• Researchers: Self-host and experiment with any AI model stack — no usage caps.

Features

• Node-Based AI Workflow Editor — Visual, modular pipelines for generative AI, similar in spirit to Krea Nodes and Weavy AI workflows but fully open-source (inspired by Blender Nodes and ComfyUI).
• Artistic Intelligence — A design philosophy bridging human creativity and AI automation; the same creative-first approach seen in FloraFauna AI and Freepik Spaces.
• Generative Image & Video — Integrated support for image and video generation powered by MuAPI (Vadoo AI).
• Self-Hosted & Private — Run entirely on your own infrastructure. No data sent to third-party SaaS platforms.
• Extensible Architecture — Add new AI model nodes, connect external APIs, and build reusable workflow templates.
• No Vendor Lock-in — Swap AI providers freely. Unlike Freepik Spaces or FloraFauna AI, you own your stack.

Use Cases

• AI Image Generation Pipelines — Build workflows comparable to Freepik Spaces AI tools or FloraFauna AI canvas, on your own server.
• Video Generation Workflows — Sequence and automate video generation jobs just like Krea Workflows.
• Brand Asset Automation — Replicate what Weavy AI does for enterprise content production, without the SaaS subscription.
• Custom Model Integration — Connect LoRAs, custom diffusion models, or any external API as a workflow node.
• Creative Exploration — Experiment with generative art pipelines in the same visual style as Krea Nodes or FloraFauna’s node canvas.

Getting Started

Prerequisites

For local development:

• Node.js (v20+)
• Python (v3.10+)
• npm (v7+ for workspaces support)

Or use Docker (see Running with Docker).

Installation

1. Clone the repository:

   git clone https://github.com/samuraigpt/vibe-workflow.git
   cd vibe-workflow
   

2. Install all dependencies (root directory):

   npm install
   

   This installs dependencies for the client, the workflow-builder library, and links them via npm workspaces.

Configuration

Vibe Workflow uses MuAPI (Vadoo AI) for generative AI capabilities. You need an API key.

1. Get your API Key from muapi.ai — sign up, navigate to API Keys, generate a key.

2. Configure the Backend:

   cd server
   cp .env.example .env
   # Open .env and set:
   # MU_API_KEY=your_actual_api_key_here
   

Running the Project

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

Running with Docker

The easiest way to run Vibe Workflow is with Docker Compose.

Prerequisites

• Docker (v20+)
• Docker Compose (v2+)

Quick Start

1. Configure environment:

   cp .env.example .env
   

   Edit .env and add your MuAPI key:

   MU_API_KEY=your_actual_api_key_here
   

2. Start all services:

   docker compose up --build
   

3. Access the application:

   • Frontend: http://localhost:3000
   • Backend API: http://localhost:8000
   • API Docs: http://localhost:8000/docs

Services

Stopping

docker compose down

Development

• Workflow-Builder Library — To rebuild the core node editor:

  npm run build:lib
  

• Client App — Uses the local library. Rebuild the library after changes if not using a watcher:

  npm run dev:app
  

Comparisons

Vibe Workflow vs Weavy AI

Weavy 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.

Vibe Workflow vs Krea Nodes / Krea Workflows

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.

Vibe Workflow vs Freepik Spaces

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.

Vibe Workflow vs FloraFauna AI

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.
