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.

The Card Caddie2025 · thecardcaddie.com · ▲11I’m relatively new to the whole “credit card game” but over the past year I’ve been optimizing my daily spending for points. In August I’m heading to Southeast Asia for a year, and I have all my flights covered using points earned just from everyday spending. Keeping track of all the different rewards categories was confusing, so I built The Card Caddie, a free tool that helps you figure out which credit card to use for each purchase to maximize points and perks. It’s pretty simple right now, but I’d love feedback, ideas, or any suggestions for features that would actually help you. Website:…
- 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…

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.…
