    The project is called QueryStorm. It uses Roslyn to offer C# (and VB.NET) support in Excel, as an alternative to VBA. I've posted about it before, but a lot has changed since then so figured I'd share an update. The current version includes a host of new features, namely a C# debugger, support for NuGet packages, and the ability to publish Excel extensions to an "AppStore" (which is essentially a NuGet repository). The AppStore can be used by anyone with the (free) runtime component. Another great addition is the community license, which is a free license for individuals and small companies…

    Srcbook (”source-book”) is an open-source TypeScript notebook that runs locally, powered by Node.js. It shines for rapid prototyping, code exploration, and collaborating on ideas. It’s inspired by Python’s Jupyter and Elixir’s Livebook. Key features: - Full npm ecosystem access - AI-assisted coding (OpenAI, Anthropic, or local models), it can iterate on the cells for you with a code diff UX that you accept/reject for a given code cell, generate entire Srcbooks, fix compilation issues, etc… - Exports to valid markdown for easy sharing and version control Try it now: `npx srcbook start`…

    I built this as a small side project to learn and experiment, and I ended up with this! I used a subdomain from my personal portfolio, and everything else runs on free tiers. The project uses Nuxt, SVG, Cloudflare Workers, D1 (SQL), KV, Terraform, and some agentic coding with OpenAI Codex and Claude Code. What started as a joke among friends turned into a fun excuse to build something end to end, from zero to production, and to explore a few things I’d never touched before. I’d really appreciate any feedback or suggestions.

    Today we’re releasing a full AI app builder in Srcbook. We released our TypeScript notebook a few months ago (https://news.ycombinator.com/item?id=41291700) and the response was encouraging, but we kept hearing that people wanted to build interactive apps. Today we are releasing just that. You can think of it as an open-source and local version of vercel’s v0. We actually think of it as something in between an IDE and that, because we believe the code matters and don’t shy away from that: you can view and edit the code in a full editor, but prompt your way forward if that's…

    I, like Andrej Karpathy, became super frustrated by how annoying it was to deploy projects that were previously an absolute joy to make with Claude Code. That is why I made open-passkey, an MIT licensed passkey repo with support for 33 languages and frameworks (examples included) that makes adding simple secure auth to a project easy. We are also releasing gateway (https://gateway.locke.id) a "backendless" hosted auth server that frontend apps can consume for free so that you can ship a React or Angular app using a CDN like Netlify without needing to configure a server at all. We…

    Hey HN, A few months ago I realized licensing my app wasn't as straightforward as I expected. There was too much setup just to create a license, and the customer experience was not great. All I wanted was for licenses to be generated automatically when I got paid, and for customers to manage their own licenses. So I built Keyforge, a simple software licensing platform for developers. It integrates with Stripe so that licenses are created automatically when someone purchases or subscribes to your product. There's also a self-serve customer portal where users can manage their licenses,…

    TL;DR- Libninja will generate world-class client libraries for you, without you needing to fiddle with openapi-generator, maintain build pipelines, and so forth. If you just want Rust, reach out, and I'll create your client library at no cost, because I want to help Rust's ecosystem grow. -- Hi HN, I got into Rust in a big way about 9 months ago. While the language is quickly maturing, one large gap in the ecosystem is immature or non-existent client libraries for common API services like Plaid, Stripe, Twilio, Github, Slack, and so on. The existing openapi-generator templates create Rust…
