What it does
Unlike most financial simulators, FinSim shows you two side-by-side scenarios so you can see exactly how carrying debt, having children, and your retirement timeline interact over decades. Debt— model your payoff timeline and see how it frees up wealth long-term. Child costs—powered by real NDCP childcare data specific to your county. Financial independence age—based on the 4% rule, updated in real time as you adjust your inputs. Built by a solo developer in SwiftUI. Free, no ads, no purchases.

I spent 2 years building a personal finance simulator2023 · projectionlab.com · ▲766Hey 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…

FinP4l - AI-assisted Financial Modeling2025 · finp4l.com · ▲7We are launching FinP4l, a life-long financial planning tool built with two core principles: actionable complexity and data sovereignty. Scenario Modeling Over Probability: We found Monte Carlo simulations to be too abstract for real life planning. Instead, our engine focuses on deterministic scenario modeling. You model specific, high-impact risk events and what-if scenarios (e.g., "What if the market crashes 50% in year 3 and inflation spikes to 8%?") to build stronger contingency plans and derive actionable conviction. 100% Local-First: Your sensitive financial data never leaves your…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
