The Best Code You’ll Never Ship

I clicked on a Hacker News thread the other day. The title was simple: “Ask HN: What programs have you written by yourself that you use regularly?”

I expected a few answers. What I got was a confession booth.

Developer after developer described the software they built for exactly one person — themselves. An expense tracker. A custom Telegram bot. A digital clock on an ESP32. A notification service that calls them via Twilio when something breaks. A file renamer that handles their exact naming scheme. A server package written entirely in C that powers their personal projects.

None of this code will ever be sold. Not a single user will ever see it. And yet, these developers spoke about these tools with a quiet, almost embarrassing pride.

The most valuable software you’ll ever write is the software nobody else will ever use.

Think about that. The tech industry worships scale. Every pitch deck promises millions of users. Every SaaS product chases the elusive product-market fit. But here, in this thread, was proof that the deepest satisfaction comes from solving a problem that matters to exactly one person — you.

This is selfish coding. And it’s the single most underrated force in software development.

Here’s why it works. When you write code for yourself, there are no stakeholders. No product managers asking for features you don’t need. No investors demanding a growth curve. No users complaining about dark mode. The only requirement is: does this make my life better right now?

The absence of stakeholders is a feature, not a bug. It allows you to iterate on a real personal pain point with atomic precision. You don’t need to abstract, generalize, or package. You just need to fix the thing that’s annoying you.

One developer in the thread built a notification service that calls him when specific events happen. He didn’t build a generalized alerting platform. He built a phone call that says “Hey, the server is down.” That’s it. It works perfectly for him. It’s a tiny, ugly, beautiful piece of code.

Another developer wrote a file renamer. Not a fancy one. Just a script that renames files the way he likes. It doesn’t support drag-and-drop. It doesn’t have a GUI. It’s a command-line tool that does one thing and does it exactly right. When you code for yourself, every line has a purpose.

But here’s the twist. This ‘selfish’ coding is actually the R&D lab for some of the most successful products in the world. The first version of almost every great software tool was built to scratch an itch. Slack started as an internal tool for a gaming company. Instagram started as a check-in app called Burbn that the founders used themselves. Even Unix was built because Ken Thompson wanted a better environment to play a game.

What looks like a side project is often the seed of something bigger. But even if it never grows, it’s still worth building. The act of solving your own problem creates a level of understanding that no amount of user research can replicate.

You’ve probably felt this frustration. You open an app store, search for a tool that does one specific thing, and you find either a bloated enterprise solution or a half-baked free alternative. You think, “I could build this myself in an afternoon.” And you’re right. So why don’t you?

Because we’ve been conditioned to think software is only valuable if it’s shared. That’s a lie. The quiet pride of self-reliance is a feeling no App Store review can match.

I’m not saying you should quit your job and build a personal OS. I’m saying that the next time you reach for a tool that almost works, stop. Ask yourself: what if I took two hours this weekend and built exactly what I need?

You don’t need to be a startup founder. You don’t need a business plan. You don’t need users. You just need a problem that bugs you and the willingness to write a few lines of code.

That’s it. That’s the whole secret.

So go ahead. Write the software nobody will ever see. It might be the most important code you ever write.
