What it does
Prism is a stateless payments library that connects your app to multiple payment processors. You can integrate once and point to any payment processor; add fallbacks for redundancy, switch processors based on routing rules - all by swapping a few lines of code. No sign-up needed. No infra setup needed. Actively maintained within the Juspay Hyperswitch production environment. Apache-2.0 licensed, polyglot ready, with SDKs for Node, Python, Java and Rust.
One library | Many payment processors | Scale to multiple processors with few lines of code. - juspay/hyperswitch-prism

- Prism.Tools – Free and privacy-focused developer utilitiesJan 2026 · blgardner.github.io · ▲380
Hi HN, I'm Barry and I've built Prism.Tools (https://blgardner.github.io/prism.tools/) – a collection of client-side developer utilities that respect your privacy. Many of these tools were used way back in the days when I ran a BBS and started my communities first ISP, serving three local communities with Dial-Up Internet, Web Hosting etc. The tools have been refined to reflect the changes in tech since then and designed for the Novice and Pro alike. As I locate more tools others may find useful I will refine and add them to the collection. Use them, Share them, or not.…
We built an open source, zero webhooks payment processorNov 2025 · github.com · ▲405Hi HN! For the past bit we’ve been building Flowglad (https://flowglad.com) and can now feel it’s just gotten good enough to share with you all: Repo: https://github.com/flowglad/flowglad Demo video: https://www.youtube.com/watch?v=G6H0c1Cd2kU Flowglad is a payment processor that you integrate without writing any glue code. Along with processing your payments, it tells you in real time the features and usage credit balances that your customers have available to you based on their billing state. The DX feels like React, because we wanted to bring…

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…

Parallel agents, diff reviewer, and multi-model comparisons
Dev tools · May 2026 · kilo.ai



Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
