Live Hackathon · July 16 to 31, 2026 · Kickoff at NPKUA Community Conference

We're hacking PKU tools live, from the conference floor.

A virtual PKU Commons hackathon that kicks off from Team Phebe's table at the NPKUA Community Conference in Chicago (July 16 to 19), then runs online through the end of July. We take feedback from families in the room and improve the open phe-estimation tools in real time, while a community of developers builds alongside us, anywhere.

A hackathon that runs where the patients are

Most hackathons happen far from the people they're meant to serve. This one runs differently: our base of operations is a table on the NPKUA conference floor, and the feedback loop takes minutes.

When

July 16 to 31, 2026

The first four days run in parallel with the NPKUA "Living Our Best PKU Life" Community Conference at The Westin Chicago Lombard; the hackathon then continues online through July 31.

Where

Virtual + our table

Build from anywhere. Team Phebe anchors in person at our conference table, collecting real-time feedback and hacking on it live.

What

Improve the open tools

The phe-estimator Skill, the living food list, and the Bluetooth scale integration. Every improvement scores on the public accuracy benchmark.

Team Phebe, anchoring on the floor

We're in the room the whole time, turning what families tell us into working changes you can watch land. Team Phebe is running the hackathon and does not compete in it.

Organizer

Nina

PKU parent, lawyer, and full-stack / infrastructure developer. Founder of Phebe and PKU Commons.

Developer

Zach

Developer on Team Phebe, shipping the real-time changes as feedback comes in at the table.

Kitchen & lived experience

Ryan

Chef living with PKU, grounding every estimate in how real low-protein food is actually cooked and portioned.

Team Phebe is disqualified from winning. We host, we judge, and we hack in the open, and the prize pool goes entirely to the community. This is our infrastructure to steward for the community.

How to join

Two ways in, build remotely, or find us at the table.

  1. Fork the repo. Start from github.com/Cureledger/pku-commons and pick a target: the phe-estimator Skill, the food list, or the scale integration.
  2. Pick a problem worth solving. The suggested hacks on the home page map real PKU pain points to concrete builds.
  3. Score on the benchmark. Every change is measured on the public accuracy benchmark. Improvements merge only when they raise the score without regressing.
  4. Post your work in our Discord. Share what you built and the feedback you got. Team Phebe reviews entries and features them at the table.
  5. At the conference? Come by our table. Bring an app, bring a frustration, bring a recipe, and we'll hack on it with you on the spot.

Prizes

A founding prize pool of $2,000, put up by Phebe, goes entirely to community builders. Team Phebe does not compete.

Sponsor the pool

This is infrastructure that no single developer, and no single company, can build alone. That's exactly why it's worth sponsoring: the standard belongs to the whole community.

Sponsors get their logo on the open accuracy standard and a seat on the judging panel. Expand the pool, add a named prize, or send a clinician, dietitian, or developer to build with us.

Get involved

Why hack in real time?

The hardest problems in phe estimation appear away from the lab, in a grocery aisle, in a home kitchen, at a birthday party. By building at the table, feedback from a family becomes a tested change the same day, and the next family to stop by sees it working.

Every improvement outlives the event. Changes merge into the open PKU Commons repos and are locked in by the public benchmark, so a tool keeps working, and keeps being trustworthy, long after the conference ends.
