Introducing Sigma Public: a Platform to Build, Share, and Grow

Some of the best learnings in the data industry come from seeing what someone else has built and realizing, "I didn't know you could do that." Sometimes it's a fresh take on a problem you've been stuck on for weeks, and sometimes it's just an approach you would never have thought to try on your own. 

Oftentimes, these ideas are shared as static screenshots on LinkedIn, X, newsletters, and online forums. Sometimes they’re presented at conferences or shared in video overviews. This type of knowledge-sharing is a great starting point; it’s an easy way to get ideas out there. But it’s tough to make the leap from “I’m inspired by this project” to “I’ve learned how to build this myself” without getting hands-on.

For a long time, this was a limitation to many people who were curious about building data assets in Sigma. Without a Sigma license—purchased by your employer—you weren’t able to access Sigma’s AI Apps and agentic analytics workspace.

I’m happy to share that starting today, the situation has changed. We’re opening Sigma Public to the entire data community for free, which means anyone can build, share, and explore assets created in Sigma—no company login required. Now the only limitation to building in Sigma is your imagination. 

What is Sigma Public?

Sigma Public is a free version of Sigma where anyone can build AI Apps, agentic analytics, and data visualizations and share them with the world. There’s no paid license or warehouse connection required. We provide sample data to get you started, or you can bring your own via CSV upload or Input Table. Once you share your asset, anyone can explore your work, dig into how you built it, and get inspired.

After you set up a free account with Sigma Public, you’ll have access to a full builder toolkit, including:

• Sigma Assistant to help you build faster and automate workflows
• Sigma Agents to create guided, chat-based experiences for end users
• AI Query to run LLM-powered analysis directly on top of your data
• Charts and controls to visualize, filter, and explore data
• Input Tables to capture and update information directly in Sigma (like tracking game scores or submissions)
  

Why I'm excited about Sigma Public

The data community is an unusually generous place, in my experience. People share solutions to problems they spent weeks figuring out, swap techniques in public, and let strangers learn from their work. Early in my career, that's how I figured things out — someone would post something they'd built, I could open it up and poke around, and I'd see exactly how it all fit together. The hands-on piece is what made things stick, and along the way I met people who still shape how I think about data.

I'm just as excited about the experimentation side of building in Sigma Public. Plenty of times at work, a tricky problem has landed on my desk and I've had that "phew, I've got this" moment, because I'd already played with the technique on my own time. The muscle memory was there when I needed it, and what would have been a slow afternoon of trial and error turned into something I could ship by the end of the day. That kind of low-stakes practice is hard to fit into a workday, because the moments when you have time to try new things tend to also be the moments when something needs to go out the door. Sigma Public is built for that kind of practice: learning based on personal interest.

There's also a career impact to sharing work on public platforms. I know plenty of people looking for new roles right now, and plenty of others trying to hire. Sigma Public is one of the easiest ways to put real technical work in front of either group. You can build something a future employer can open, click around, and explore on their own, which is one of the strongest signals you can send when you're trying to land an interview or convince a candidate to take a role.

With Sigma Public, the Sigma community finally has a place built for all of these opportunities (and more!). I can't wait to see what shows up here.

Ideas for your first builds in Sigma Public

Try a feature you've been curious about

There are probably things you've seen in a demo or heard about in a webinar that you've never quite had time to test, and Sigma Public is a consequence-free space where you can figure out how something works before you bring it into a real project.

For example, learn how to build an Agent that turns social media reviews into actionable insights. You can test out new app layouts with page panels and the navigation element for easy guided exploration, or use repeated containers to create interactive cards.

Share a solution that took you a while to figure out

If you worked out a clever formula, a dynamic control setup, or a layout pattern that makes something complex feel simple, share it with the community, because somewhere out there is another analyst working through the same problem right now.

For example, in this build, I show off how to combine a context menu action with a parameter field and a robust formula to dynamically create groups. This lets folks create new groups on the fly to compare different collections. 

Build a portfolio piece

If someone were building a portfolio, it’d be a good idea to include work like Lynda Choa's Everest HR Overview. Sigma's 2026 Golden Goat winner built an HR app that brings workforce planning, candidate pipelines, and approval workflows into a single workbook, surfacing hiring risks early and routing approvals automatically when something needs a closer look. A hiring manager could click around in it and figure out exactly what kind of builder you are.

Settle something with data 

If you've ever wanted to prove a point with actual numbers, this is the place for it. It could be proving your favorite sports team or player is the best, playing a fun game, sharing your take on a TV show, or whatever else you've been sitting on and want to put the receipts behind.  Sometimes, the most fun is getting to dig into a topic just because you want to. 

Using data to dig into a personal obsession, this Sigma Public workbook turns Formula 1 history into an interactive deep dive, with a Race AI agent ready to talk through any race.

Join a community challenge

Workout Wednesday is a weekly community-run Sigma challenge. Each week, a community member shares a finished build along with a few simple prompts, and it's up to you to recreate it. It's one of the fastest ways to sharpen your Sigma skills, pick up new approaches from other builders, and have some fun along the way.

With Sigma Public, you can post your take on each challenge, browse what others have built, and see how different people approached the same problem.

What people are already building in Sigma Public

The best way to get a feel for what Sigma Public can do is to poke around and interact with what people have already built. It’s been exciting and inspiring to see the creativity and range come through in the early builds. There has been everything from simple solutions to everyday problems to full-on interactive games. Here is a small sample to get you started. 

Nutrition Calculator by Brian Davis

Punch in your stats, and this workbook does the caloric and macronutrient math that everyone tends to fudge when they're meal-prepping.

Mmmoon Baked Goods by Mariana Luna

This workbook turns picking the next office treat into a small, democratic event, with ranking and voting built in.

Plugs Electronics Heist by Chris Goodman

This app is a whodunnit you solve by querying suspect data and navigating filters as clues, which is probably the closest thing to a Sigma escape room out there.
