A one-person lab for sites, apps & AI
Undefined Labs turns loose ideas into custom websites, apps, and AI tools. Send a few sentences today and a designed page comes back tomorrow, free.
un·de·fined adj.
ant. launched
Recent work. None of it looks alike, which is the point.
Lab product
Personalized picture books starring the kid you know best.
Parents put their child’s favorite people, pets, and wild what-ifs into an illustrated story. The same characters look the same from book to book, and the family approves every edition before it prints.
Lab product
An app for furnishing a home with other people.
Moss replaces the group chat full of furniture links. Save a find from any store with your phone’s share button, sort it into a room, then vote and decide with your household or your designer.
Client site
A booking site for a working guitarist that also works during the gig.
Dave plays waterfront bars, weddings, and community events across Southwest Florida. His old site was a page-builder template. The new one gets him booked, and then it comes to the show.

A wedding, run like software
The guest site was the easy part. Behind it, RSVPs sync to a spreadsheet and every vendor gets a run of show with only their own cues.
An AI lesson planner for teachers. Prep went from two or three hours to under ten minutes, and the first version shipped in six weeks.
A quiz with one question, asked repeatedly. Featured on Product Hunt in 2018. The lab’s oldest surviving experiment.
left: llama. right: alpaca. probably.
Three kinds of things, all made to order.
01
Custom sites for businesses, performers, events, and anything else with a story to tell. Each one is designed around your real material, launches in a few weeks, and costs almost nothing to keep online.
See: Dave J Rocks
02
Most small operations juggle tools that don’t talk to each other. The lab wires them into one workflow, so information gets entered once and shows up everywhere it’s needed. When the missing piece doesn’t exist, it gets built.

03
ChatGPT has never heard of your business. The lab builds a private home for everything your operation knows, and an assistant that works from it. You approve every change before it becomes fact.

Posted on the wall. Followed, mostly on purpose.
01
Your site should look like your business and nobody else’s. Scroll up and compare the three above.
02
The domain, the code, and the hosting live in your accounts. If you ever leave, everything leaves with you.
03
The press kit fits on one page. The picture book keeps the dog the same color in every chapter. Somebody has to care about this stuff.
04
The lab builds with AI every day and builds AI for clients. Anything that matters still gets a human’s yes first.
05
Most sites launch in a few weeks. That speed comes from years of learning which parts a project doesn’t need.
Justin
Founder, designer, engineer, and the person who answers your email.
Justin spent eight years building software at a healthcare startup, joining as an intern when it was ten people and staying as it grew past a hundred. That meant leading engineering teams, building the system every other team builds on, and now leading the company’s shift to working with AI.
That work involves sensitive medical records, where “it works on my machine” doesn’t cut it. The same standard applies to a guitarist’s website.
also the janitor
From “sort of an idea” to a live link.
01
A few sentences is plenty. Half-formed is fine. That’s what the name is for.
02
One designed page made for your project, plus a straight answer on fit, timing, and a fixed price. The mockup is yours to keep either way.
03
A live preview link arrives in the first week. Feedback usually shows up in the next day’s version.
04
It goes live in accounts you own, and nothing on it expires or needs patching. Want a change later? Send an email.
Bring something undefined. Get a free mockup in 24 hours.
A few sentences is enough, and rough is fine. Within a day a mockup lands in your inbox: one designed page, made for your project. You see the direction before any money changes hands.
a real person reads every one of these
Got it. Consider it defined-ish.
Your mockup lands in your inbox within 24 hours, read and answered by Justin directly.
Your email app should have opened with everything filled in. If it didn't, send those answers to hello@undefinedlabs.dev and the clock starts the same.
The mockup is free and yours to keep. There's no obligation to go further.
