Introducing the Fabric Extensibility Toolkit Contest 🎉

[slindsay]

Showcase Your Creativity. Build Something New. Shape the Future of Fabric.

We’re thrilled to announce our newest community challenge: the Fabric Extensibility Toolkit Contest - your chance to build innovative workload items, inspire the ecosystem, and help ignite the momentum behind Fabric extensibility.

Over the past few months, interest in the Fabric Extensibility Toolkit has exploded. Let’s keep that momentum going!

We designed this contest with one core goal in mind: ✨ Inspire creativity across the Fabric community ✨

The Toolkit puts the full flexibility of the platform into your hands - whether you’re building new UX components, interacting with Fabric APIs, spinning up Notebooks, creating shortcuts, or shaping entirely new item types. Getting started takes about an hour, and a solid idea can come to life over a weekend of work.

What You’ll Build

This contest is not about shipping a fully polished, production-ready Fabric workload. Instead, it’s about ideas brought to life - showing what’s possible, not delivering a GA-ready product.

You can submit:

✔️ A partially implemented or simplified workload
✔️ A prototype that demonstrates your concept
✔️ A mocked or partially functional UX flow
✔️ A demo video walking through the scenario
✔️ A lightweight GitHub repo with sample code, scaffolding, or stubs
✔️ Visuals like screenshots, diagrams, or GIFs to convey the experience

Building with the Toolkit is quick to start (often under an hour), and many concepts can be explored in a weekend.

The judging will focus on:

• Creativity of the idea
• Integration with Fabric
• Value to customers
• Potential for reuse

The judging will not focus on: completeness of implementation.

Bottom line: Build something interesting, show your idea clearly, and help us imagine what’s next for Fabric.

Submission Requirements

When you’re ready, submit an entry in the Extensibility Toolkit gallery that includes:

Required

• Workload Description
   What it does, what problem it solves, who it’s for.
• Demo Video
   A short walkthrough of your concept (recorded however you like).

Optional

• GitHub Repository
   Code, scaffolding, or even conceptual stubs. Fully working code is not required.
• Publishing Link
   If you’ve deployed it to your tenant and want us to explore it.
• Screenshots, GIFs, or UX Mockups
   Anything that helps communicate the idea.

Judging Criteria (0 - 10 points each)

• Creativity
• Fabric Integration (Lakehouse, RTI, APIs, etc.)
• Value to customers
• Shareability (published experience or GitHub repo)

Selection Process

1. Preselection of the top 5 workloads (blind-rated by judges Gerd Saurer, Teddy Bercovitz, and Aviv Ezrachi)
2. Final review by celebrity judges Kim Manis and Amir Netz!

Resources to Help You Build

Here’s everything you need to hit the ground running:

• Fabric Extensibility Toolkit Docs: https://learn.microsoft.com/fabric/extensibility-toolkit
• Starter Kit: https://github.com/microsoft/fabric-extensibility-toolkit
• Samples Repo: https://github.com/microsoft/Microsoft-Fabric-tools-workload/

The Toolkit repo is AI-enabled - meaning you can ask it how to get started, how to scaffold a new item, or how to design your UX component… and it will help you generate code right inside the environment.

Why You Should Enter

Beyond bragging rights, visibility, and community recognition, top entries will:

• Be showcased on the Fabric Community Blog
• Promoted across LinkedIn and partner channels
• Featured in community livestreams and partner sessions
• The top entry will win a free conference pass to FabCon ATL!

Ready to Build the Next Great Fabric Workload?

We can’t wait to see what you come up with - whether it’s a new developer tool, a smart deployment workflow, a customer-facing experience, or something entirely unexpected.

You’re helping shape the future of how developers extend Microsoft Fabric.  Let’s build something incredible together. 🚀
