I built a tool to manage and compare credit card rewards
This is a free tool that helps you manage and visualize your credit card rewards across different categories. You can input the cards in your wallet and see how they complement each other, spot gaps in your setup, and also see the best card to use for a given merchant. I’m also a founder at OneCard, where we’re building a smart card that’ll eventually handle all of this automatically, routing each purchase to the best card in real-time. Would love feedback from the HN community!
In plain words
This free tool helps users manage and compare credit card rewards across different spending categories. Users input their cards to visualize how they complement each other, identify gaps in coverage, and determine the best card for specific merchants. The tool is designed for people with multiple credit cards who want to optimize their rewards strategy by understanding their complete portfolio and making informed spending decisions.

- WBWe Built a Dashboard for Merchants to Track and Optimize Payment Fees2025 · hypersense.io · ▲15
Hello HN Viewers, So this all started when we got super frustrated trying to figure out payment fees. You know how it goes – you have got a bunch of payment providers, each with their own fee reports, and trying to make sense of all that mess is quite challenging and complex. We thought, why not just build something that pulls all those fee reports together, cleans them up, and makes them actually understandable? So we built a tool that pulls in fee reports from multiple providers, standardizes fee names, and makes it easier to understand all fee types. You can drill down to see the exact…
- IBI built a tool to talk to Stripe data2024 · dataraccoon.io · ▲7
Hey HN! I am a developer working on a startup doing lots of payment integration stuff with payment providers like Stripe. I built a tool to talk to Stripe data, just so that I can answer questions from our team. I turned that into analytics tool (sort of) to answer questions about MRR, churn, revenue etc. (https://www.dataraccoon.io/). There is a two minute demo video on the page if you want to see how it works, or you can use free trial without needing a credit card. I was wondering if you would use such a tool directly in Slack or prefer receiving messages about your metrics…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
