I made a simple personal finance API (like Yodlee)

In plain words

Finkin is a personal finance API that lets developers quickly access banking and financial data from multiple institutions via HTTPS. Designed for simplicity, it requires minimal setup time and stores no access credentials. Unlike more complex competitors, it prioritizes developer experience with straightforward integration. The service operates on a pay-per-request model and is currently in beta testing before moving to a dedicated infrastructure with guaranteed uptime.

From the sources

In the maker’s words, at launch

It's at http://finkin.com. The goal is to allow a developer to sign up in seconds, and within minutes begin querying data. It runs under https and stores no access information. From http://news.ycombinator.com/item?id=1431583, I realized that all those types of sites are not tailored to developers like the other…

  RayApr 2026 · rayfinance.app · ▲298

  I'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.

  FinBodhi – Local-first, double-entry app/PWA for your financial journeyNov 2025 · finbodhi.com · ▲40

  We built a local-first, private, multi-currency, double-entry based personal finance app. It will help you track, visualize, and plan your financial journey. Use the `Try demo` button, to try it without an account. Small screens (mobiles) are not supported yet. By local-first we mean, your data is on your system (we use sqlite over opfs, in browser). For synching across devices, the data is encrypted with your key before it leaves your device. You can backup the data locally (if you are using chrome) and/or to your dropbox. It's designed so that we (the people building it) can't access…

  Hi HN! I'm excited to share that Treasury (https://treasury.sh) is now available on the iOS App Store. Treasury is a personal finance app I've been building, and we just opened up our public beta. We'd love your feedback. Currently, Treasury has a set of core building blocks that let you create financial setups as simple or as complex as you want. You can track your net worth, analyze spending, spot recurring transactions, and build budgets that actually match how you think about money. Download it from the App Store and let me know what you think.

  Talanoa▲346

  Hi 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…

  I asked an HN member for feedback and she blew my mind▲453

  A few days ago, I responded to a comment by bloggergirl offering to read anyone's web copy and help. I shot off an email hoping for a paragraph or two of feedback on my startup's copy. Instead I received a professional, detailed deck of tons of invaluable well thought out feedback. It must have taken her an entire afternoon. Here's a link to it: http://www.slideshare.net/shereefb/recommendations-for-bettermeans To top it off, this isn't someone with a lot of free time on her hands, she's only days away from launching her own startup (page99test) This community blows my mind!

  Review my project: MarkUp, a tool to draw on any webpage.▲90

  Here's the website: http://markup.io/ We created MarkUp at Medium to help make the QA process better for sites we're working on. Grab the MarkUp bookmarklet, go to some page in your browser, then click it to draw on the page. Publish to make a link you can share. We've tried similar tools like BounceApp, Notable, and Skitch. Everything else we found is screenshot-based or takes us out of the browser. We wanted something that felt quicker than screenshots and more integrated with the browsing experience. Instead of taking a screenshot, MarkUp snapshots the DOM in the current page, strips the…
