Vibe-Workflow

Vibe-Workflow is an image-generation tool - Free, open-source alternative to Weavy AI, Krea Nodes, Freepik Spaces & FloraFauna AI — node-based AI workflow builder for generative image & video pipelines.

Overview

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.

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 is open-source, written primarily in JavaScript, with 427 GitHub stars under the MIT license. It was last updated on 2026-06-02.
