In plain words
This is an open-source API for financial ledger management built with Clojure. It's designed for developers who need to integrate ledger functionality into applications. The software provides programmatic access to financial record-keeping through a web API, making it suitable for fintech projects, accounting software, or any system requiring transaction tracking and balance management. Being open-source, it allows developers to inspect, modify, and contribute to the codebase.

- AAAn API to store balances and transactions2020 · ▲151
Hey everyone! I'm Rob and I want to share what I've built - a solid ledger behind simple API: https://decimals.app The ledger is a key piece of any financial system and is easy to get the design wrong, resulting in troubles for making sure money movements are adding up. I took a lot of inspiration from good designs from Square, Uber, and others for the scalability and security aspects. And on the usability side, I applied many concepts from the Ledger CLI, making it very easy to use. I'm really happy I get to show this to you all, thank you for reading about it! Please let me know…

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.

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Almost eight years ago I launched an online “Linux sysadmin course for newbies” here at HN. It was a side-project that went well, but never generated enough money to allow me to fully commit to leaving the Day Job. After surviving the Big C, and getting made redundant I thought I might improve and relaunch it commercially – but my doctors are a pessimistic bunch, so it looked like I didn’t have the time. Instead, I rejigged/relaunched it via a Reddit forum this February as free and open - and have now gathered a team of helpers to ensure that it keeps going each month even after I can’t…
