Community extension: Next.js plugin built on top of the Workflow Builder Template

Hi everyone 👋

I wanted to share a community project built around the Workflow Builder Template.

Originally I opened an issue proposing a plugin marketplace (see #175), but the project has since evolved into a full Next.js plugin implementation demonstrating how to extend the template with modular integrations.

The goal of this project is to provide a practical example of how developers can extend the Workflow Builder using the same architecture and conventions defined in this repository.

Key ideas behind the project

• Modular integrations following the same directory structure (credentials, icons, steps, etc.) • Standardized step execution using the stepHandler pattern • Declarative configuration using configFields for consistent UI generation • Easily reusable plugins that developers can add to their own Workflow Builder deployments

Current development status

The project is currently in an active development phase and is intended to evolve into a richer extension of the Workflow Builder ecosystem.

Some foundational workflow nodes have already been implemented, including:

• Switch • Loop • Merge

The roadmap includes adding more built-in workflow utilities, MCP server and integrations, with the goal of providing capabilities similar to what tools like n8n offer, while staying aligned with the architecture of this template.

If useful for the community, it might be helpful to reference this project in the Resources or Community section of the README as an example extension built on top of the Workflow Builder Template.

Thanks again for providing such a solid foundation — it’s been great building on top of it. I’d love to hear any feedback!
