Personal Software
I used to track my expenses in an excel sheet and later in YNAB. The bank i use remains unsupported there, and i had to enter my transactions manually, no biggie, i was already used to it.
Back in May 2026, YNAB updated their Transactions screen and it got properly annoying to enter transfers manually between my own accounts. And i was not the only one. LHV has this nifty feature where it rounds up every transaction to the nearest euro and sends the difference to an investment account. I had two investment accounts. So for every transaction, i had to manually input three transactions to YNAB. I don't usually count the number of "inputs" required to complete an action if it makes sense, but in this case it really didn't.
So when LHV announced they have an MCP server1 to read data from your accounts, i also noticed that you can access them via an API. Hello there! A few prompts and i had data going from LHV to YNAB. A few evenings later i had it deployed on my home server syncing my LHV accounts with YNAB every 10 minutes. Years of manual input no longer needed, neat. And i got to tinker with designing and animating a CLI, even though it ended up running headless anyway.
Thinking
The thing i kept pondering was how accessible coding has become. In the past your options would have been to learn to do it yourself, buy what someone else made and / or pay someone to do it for you. Today it's enough to just have the tools and, in my case, to be annoyed at something. I have no commercial interest or motive here, and anyone else can do the same. Whether you start by copying an open-source project and adjusting it or build something from scratch, you can make it your own.
On the flip side, i can totally see some personal software become the r/DiWHY of code. It's not stupid if it works though.
