Deductly
Hey HN, I'm a tech founder — 15 years building software, fintech background, been through the early startup grind before. I thought I knew how to run a business. Then I opened a restaurant. And I got humbled fast. Nothing in my background prepared me for how financially opaque restaurant operations actually are. Sales looked fine. Cash kept disappearing. By the time my P&L landed, the damage from a bad food cost week had already compounded twice. I was running a margin business in the dark. So I did what I always do: I went deep. Down to the penny. I connected every data source I had — Toast…

RayApr 2026 · rayfinance.app · ▲298I've been using this daily for 4 months and figured others might find it useful. This is my first open source project so would love any feedback. Ray connects to your bank via Plaid, stores everything in an encrypted local SQLite database, and lets you ask questions about your finances in natural language. No cloud, no account, your data is stored on your machine. Before anything reaches the LLM, all PII is stripped — your name, companies, transaction details are redacted and replaced with tokens, then rehydrated locally in the response. The AI never sees who you are.

Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn't cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven't written real code in years. Fast forward to now. I'm a Buffett nerd — big believer in compound interest as a mental model for life. I run compound interest calculations constantly. Not because I need to, but because watching numbers grow over 30-40 years keeps me patient when markets get wild. It's basically…
Write It Down – Personal finance tracker2025 · write-it-down.com · ▲271Everyone’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…
Fina2023 · fina.money · ▲257Fina lets you build your own tracking system with live financial accounts all without using a spreadsheet. You can build and share custom templates the same way you can in notion.
Quanta2025 · usequanta.com · ▲120Hello! I’m an engineer who has spent the majority of my career building financial systems and ledgers in fintech. A theme across those years was how painful traditional accounting software was to use, so I set out to build something better with Quanta. The best way to get started was by building software that would enable the best full-service accounting experience, as well as help business owners understand their business. If you have a software business, I’d love for you to check out our free trial. Any feedback appreciated. Thank you!

The site hit #1 on HN about a year ago. Got enough traffic that I turned it into a proper API. What's there: - REST API — 35k products, manually filterable by category, free key, 60 req/min - CLI — npx anycrap random -c food - faker.js plugin — bundled, no API call, works offline - HuggingFace dataset — full 35k rows for ML/training https://anycrap.shop/developers

I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
