Why Did I Build a Golf Tee-Time Tool Myself, and What Does the Era of Solving Your Own Frustrations Mean?

To book a single weekend round, I used to comb through more than a dozen sites one by one -- so I built a tool that compares tee times at 34 of Korea's popular golf courses on a single screen. I gathered, in real time, only the non-affiliated popular clubs that major booking apps don't cover, and with no intent to monetize, my friends and I now use it for actual bookings. The point is that we've entered an era where the person who feels a frustration can solve it themselves through vibe coding.

Why Were Popular Courses' Tee Times Always Scattered?

To book a single weekend round, I used to go through more than a dozen sites one by one. The more popular the course, the faster the slots vanish -- yet the tee-time information was scattered all over the place, so opening any one site never showed me the whole picture.

It's not that major booking apps don't exist. It's that the popular courses I actually wanted to play often weren't covered by them, so opening several sites in turn each week and repeating the same check had become part of my weekend routine.

So What Did I Build Myself?

So I built it myself: a tool that compares tee times at 34 of Korea's popular golf courses on a single screen. I selected only the non-affiliated popular clubs that the major apps don't cover, and gathered the scattered tee times into one place in real time.

There is no intent to monetize. My friends and I now use it for real bookings, and I'm content for it to remain simply 'a case of solving a small everyday frustration with AX.' It was never meant to be some grand service -- just a tool to remove one frustration I ran into every week.

What Change Does This Case Show?

Here's the point: we've entered an era where the person who feels a frustration can solve it themselves. In the past, a tool like this had to be requested from someone and waited for; now the person who feels the frustration most acutely can become the one who builds the fix right away.

This is exactly what I pay attention to as an AX consultant. The point isn't the tool itself, but the fact that the distance between 'feeling a frustration' and 'solving it yourself' has disappeared. I hope everyone can solve their own everyday frustrations directly through vibe coding.
