Post a build

Post yoursThe screens, one line on what it does, and what’s left to make it real. Below.

In response to I built a fantasy trading-card pack opener with Claude Code, one small request at a time by @sjurskarphol. Credit stays with them.

The screens

We host these, so nothing has to be deployed. An app that only runs on your laptop counts.

Drop your screenshots or a screen recording here

PNG, JPEG, GIF, WebP, MP4, MOV or WebM. Up to 8, 8 MB each.

Tip: a 10–20 second recording of the app working makes the best cover. Put it first.

What it is

TitleSay what you did, not what it is called. “I built a timer with one giant dial” beats “Tomato”

What happened?Two or three sentences: what you built, why, and what came out — at least 20 characters

What made it work?Optional. One point per line — shown as bullets near the top. This is the part other builders copy

A question for people who see itOptional, one line. It goes up as the first comment, so the thread starts with you

The prompt that did the heavy liftingOptional, and the thing people come here for — paste the one that got it working

What’s left to make it real

Optional. Where it goes next — what the real version needs, said specifically enough that somebody could pick it up instead of starting again. “Needs a live feed instead of the CSV I exported by hand” says more than “needs work”.

Who can see it?

You can change this later on the build’s page.

Add more detailsOptional: tools, time spent, how you made it, links. You can add these later.

AI tools usedComma separated

Time spent

ModelIf you know it, the model behind the prompt

How did you make it?

What was difficult?

Live linkIf it is deployed somewhere

RepoIf it is public

This posts as a response to another build. Credit stays with the original, and it appears on their page.

I’ve read the rules and this build follows them. It’s my own work, and the screenshots show no real people’s data or secrets. If it resembles somebody else's product, it copies none of their logos or assets and does not touch their systems. Read the rules

A build is your responsibility. If a company asks us to remove it, we will — see the rules.
