Hey everyone! After another year of building as a solo dev on nights and weekends, I'm back with an update on this post: https://news.ycombinator.com/item?id=31083093. TL;DR - ProjectionLab (https://projectionlab.com) is a privacy-friendly personal finance planning tool where you can create financial plans that go beyond the standard online retirement calculators. And by popular request, it now supports self-hosting for Lifetime users! Something I'm grateful for is that our community here on HN is the difference between PL existing and not. There was actually a time…

Everyone’s chasing AI hype. I built a Google Sheet and it quietly took off. In 2020, I made it to track my own finances for income, expenses, savings, yearly summaries etc. I shared it once on Reddit, forgot about it for a year… When I checked back, it had over 130k views and I was honestly stoked! No launch. No funding. No AI. Just a spreadsheet people actually stick with and find useful. I finally gave it a proper home: write-it-down.com Now, more than 2,300 people use it. It’s intentionally boring and that’s why it works. People don’t always need AI. They just need something that actually…

My Expenses is a very simple app to track expenses for one-time budgets. Let's say you're going on vacations in Italy and you want to allocate $1.500 to this trip. You create a budget "Italy" in 30 seconds and you're ready to go. Each time you make an expense in Italy, you add it to the app in a few seconds and you instantly know you're remaining budget. I'm bored of super complex apps. Yes, they do a lot of things, but it often takes a while to get used to the app and understand all its features. That's why I created this app. I want people to be able to track their expenses in seconds, as…

Hey everyone! I'm back with an update on this post [0]. Last year, I quit my corporate job and went full-time on ProjectionLab, the long-term financial planning app I've been building for the past 4 years, which some of you may recognize. The decision to go all-in felt like a huge leap. But it was the right call, and it's been a good year. And without the HN community, it would not have happened. As I mentioned last time [0], the feedback on my original Show HN is THE reason I'm still here working on this. I'm really grateful for that. And I hope the way I’ve grown PL -- staying bootstrapped…

Hi everyone, I’ve been on Hacker News for a good number of years, but this is my first “Show HN”. I changed jobs recently. Tax is weird in Europe (and maybe other places as well?) in that different amounts go out at different times and repeat at various intervals. I needed to make sure I had enough cashflow to make all upcoming payments, I didn't want any surprises. So I created a little tool for my own purposes, then had fun putting a small HTML frontend on it as I thought it might be useful for someone else. I'm a backend developer in my day job, as you can probably tell from the design :)…

For years, I have struggled to understand my cash flow and save for the future. In addition to that, my wife has many credit cards and accounts that complicate matters. I am building a tool that connects all our accounts, helps us create a budget, and tracks and adjusts expenses on the fly. I am also sprinkling some AI magic on it for financial suggestions. I am looking for feedback on the implementation. More importantly, I am looking for more beta testers to improve the product.
