Built the app I've always wanted in a day
I've always wanted this app called QLab on Windows, it's a mac-only audio and video cueing app used in live performance and really useful for a lot of things but the devs refuse to make a windows version. I've also always wanted to be able to build a self-contained executable app I could hand off and run anywhere. I never had time to attempt to build any of it until now. ## Spec before scaffold Shout out to @Ari Evergreen and @Noah Taylor , I applied the Spec writing guidelines and vibe coding rules they shared and that really helped write a strong spec document. I didn't have enough background to choose a stack on my own, laying out the spec gave Claude enough to work through the tradeoffs and help me make the call. This also helped break down the build into 5 phases that made it manageable, worked with the $20 tier Claude session limits, and in 1-shot built the image display portion of the program. ## Use case determining build order I wasn't sure how long it would take me not having built a full app before, so I prioritized feature build out by what I expected to be used the most. That single constraint resolved phase order, feature priority, and stack choice simultaneously. ## Full app built in a day while multi-tasking at work What I didn't expect was to have the app working after phase 1. That was super exciting, and what was even cooler was I was able to continue building in the background while at work, answering questions and tweaking behavior as needed while doing my normal work. By end of day the full app was built — a fully self-contained .exe, QLab on Windows, tailored exactly to how I work. --- attached is short video demo and a simplified step by step of how to think about building an app for yourself. This is assuming you've build the file system architecture from Foundations. Thanks so much to @Jake Van Clief and Ari and Noah and @David Vogel , in the last 2 weeks it feels like the world is completely different now.
