Inspiration

We noticed a growing disconnect between technical workflow automation and the clarity non-technical stakeholders need. Inspired by the worlds of UI/UX prototyping, game design, and visual storytelling, FlowCraft was born to make workflow design as expressive, interactive, and intuitive as building with Lego. It's a creative response to friction—between humans and their tools, and between ideas and execution.

What it does

FlowCraft is a visual workflow prototyping studio built on Node-RED that empowers teams to:

Rapidly map and test ideas using modular flow components

Integrate real-time data for dynamic decision-making

Present workflows with user-friendly narration and tooltips

Export production-ready Node-RED JSONs

Add human-in-the-loop logic with approvals and feedback capture

How we built it

We leveraged:

Node-RED subflows for modular design

Custom UI templates via node-red-dashboard

MongoDB Atlas for storing dynamic flow metadata

Draw.io for prototyping pre-build logic

Postman + custom scripts for API stubbing and testing

Git-based version control using Node-RED Projects Everything was stitched together using an iterative process—prototyping, user feedback, and gradual scaling.

Challenges we ran into

Ensuring dynamic payload adaptability across varying nodes

Managing flow state and rollback without overcomplicating logic

Keeping the visual interface clean while embedding business logic context

Avoiding edge-case errors in nested subflow executions

Balancing backend performance with frontend interactivity during simulations

Accomplishments that we're proud of

Created a reusable workflow boilerplate that slashes prototyping time

Enabled non-technical stakeholders to validate automation logic visually

Built internal debugging dashboards with actionable error trails

Successfully integrated Postman and MongoDB validation flows seamlessly

Reduced onboarding time for new contributors with visual story mode

What we learned

Visual clarity is as critical as logic accuracy in workflow automation

Teams collaborate better when logic has narration and context

Subflows are powerful, but require discipline to prevent nesting chaos

Real user feedback during prototyping improves the final flow quality exponentially

What's next for FlowCraft

A “FlowChoreography” mode to narrate each step as a process story

Natural language input to auto-generate flow skeletons

Integration with tools like Slack, Webflow, and Make.com

A deployable SaaS version with team management, audit trails, and flow sharing

Optional AI assistant (yours truly!) to recommend optimizations and catch anti-patterns
