Launch HN: Sonarly (YC W26) – AI agent to triage and fix your production alerts

Hey HN, I am Dimittri and we’re building Sonarly (https://sonarly.com), an AI engineer for production. It connects to your observability tools like Sentry, Datadog, or user feedback channels, triages issues, and fixes them to cut your resolution time. Here's a demo: https://www.youtube.com/watch?v=rr3VHv0eRdw.Sonarly is really about removing the noise from production alerts by grouping duplicates and returning a root cause analysis to save time to on-call engineers

How to get an AI to check your schematic

Z.ai/GLM-5: "if I needed a schematic checked for possible design issues, is sending you the netlist the best way ?" *No, sending just a netlist is usually not the best way.*While I can process a netlist, it is the equivalent of reading a phone book to understand the plot of a novel. You lose all the visual context, component values, and spatial relationships that are critical for catching design errors.Here is a breakdown of why the netlist is difficult to work with and the best

Show HN: Alexa-like voice interface for OpenClaw

I’ve been experimenting with running OpenClaw fully locally on a small PamirAI Distiller Alpha device. Something interesting happened: OpenClaw detected the device had an unused microphone + speaker, and I ended up wiring a full local voice interface on top of it, wake word, audio pipeline, and agent loop, all running 24/7 on-device.The result is a completely local, always-on AI agent I can talk to anytime (no cloud, no external APIs required). It executes real tasks, manages memory locally

Show HN: GPU-accelerated search for Bitcoin keys generated with weak entropy

Hey HN, I've been working on a CUDA pipeline that systematically searches for Bitcoin private keys generated by flawed software from Bitcoin's early years. The linked article is a technical deep dive into the GPU engineering — no source code (project is closed-source), but detailed pseudocode and architecture diagrams. The problem: Between 2009 and 2012, many Bitcoin wallet tools used predictable entropy — timestamp-seeded LCGs, brain wallets with simple passwords, the Debian OpenSS

Tell HN: A production-ready "Hello World" is now ~600 files

I recently ran an audit on our latest full-stack repo to figure out why "spinning up a new project" felt like such a heavy lift. I counted every file required just to reach a "production-ready" baseline—before writing a single line of unique feature code.The count was roughly 600 files.To be clear, I'm not talking about a `create-react-app` sandbox. I mean a compliant, scalable SaaS foundation: Next.js frontend, Node.js/NestJS backend, mobile wrapper, CI/CD pip

Show HN: Recursive – AI support agents for small businesses

I'm a solo developer who's been writing code for 26 years, mostly consulting work in computational geometry and CAD software these days. A month or two ago I watched a YouTube video about using an AI agent as a resume assistant, and thought it sounded like a fun idea. More importantly, it sounded like something I could actually learn to build quickly.Around the same time my longest-running client, a small company that makes a SolidWorks plugin, needed a better way to handle technical

Tell HN: We analyzed our dev time.80% is still infrastructure'setup',notfeatures

We recently did a deep dive into our engineering time allocation for a standard 5-person team building a B2B SaaS application. The results were pretty depressing: we spent roughly 960 hours (annualized) on "setup" tasks—environment config, auth flows, RBAC, CI/CD pipelines, and database scaffolding—before we built a single unique feature that actually differentiated the product.I’m sharing this because I think we’ve become numb to the "Setup Tax" in web development. We a

To ReAct or not to ReAct?

Recently I've been learning about [LLM-powered ReAct architecture](https://arxiv.org/pdf/2210.03629) for designing software solutions. I've also worked on a high-scale production implementation of this approach, which got me thinking about all the applications I've built in the past.Theoretically, any of them could be implemented using the ReAct architecture(I encourage you to go through the same though exercise), but I'm still grappling with when this mak

The End of Nue Framework

Hello HN. I want to share something I’ve been thinking about for a while now. I’m stepping away from Nue [1][2] development to work on something new. This wasn’t an easy call, but I think it’s the right one. Here’s why.[1]: https://github.com/nuejs/nue [2]: https://nuejs.orgThe ecosystem chose React and TailwindI spent two years making the case for a simpler, standards-based alternative. Better architecture, faster builds, less complexity. None of it mattered. The f

Ask HN: Feedback Loop with Coding Agents?

I've been using Claude Code ever since it came out, and I've seen good success with it. However, Matt Shumer's recent article [1] included a piece I'm curious about:When describing his workflow now, he says "Then, and this is the part that would have been unthinkable a year ago, it opens the app itself. It clicks through the buttons. It tests the features. It uses the app the way a person would."Unless I missed a major development, do these coding agents have the ab

Ask HN: How are you working now?

Anders Ericsson argued that high-touch mastery - elite human capabilities - takes on the order of 10k hours of focused development.I personally started adopting LLMs into my workflow with Sonnet 3.5, which was released June of 2024. Sonnet 3.6 was released in October of the same yearTry as I might, I couldn't plug 625 hours per week of deliberate practice in that window. I never achieved Sonnet 3.5 mastery.---There has a steady stream of blog content on the "How I program with LLMs (in

Show HN: LockFS is a flexible file-by-file encryption for secure storage

It is currently in its early development phase. However, the core implementations are ready for testing and ready for feedback but it's not yet feature complete yet.<p>If this fits your workflow, feel free to use it and stress-test it. Questions, suggestions, and contributions are welcome to help make LockFS better.

Outreach

We had a call with a large accountancy firm and they gave us some really good feedback. However, we couldn’t convert them into a development partner because of IT security and compliance constraints. Right now, we are testing and getting traction with mid-sized and smaller accountancy firms, but their processes are not as complex, so automation does not feel like a major value add for them. Bigger firms are where the real complexity and value are, but they are much harder to work with early on.

Built and shipped an iOS app from my phone while traveling Japan

My wife and I built and shipped a simple iOS app without writing a single line of code in the traditional sense.She hates when I bring my laptop on trips. I love building things. This was our compromise.I had been wanting to experiment with building an iOS app using Claude Code. I had never built for iOS before, and the idea of exploring it through AI-assisted development felt like a new frontier for me. But bringing a laptop to Japan again would not go unnoticed, and not in a good way.So I made

How I See Front End Evolving

Many posts claim that "development is becoming obsolete" but they rarely discuss what software evolution actually looks like.Yes, a growing portion of development, especially frontend boilerplate, is becoming automated. But automation doesn’t eliminate development; It changes its shape. The real question isn’t whether coding disappears. It’s: What does development become when repetitive UI work is largely automated?Here’s one direction I see emerging: the rise of variable frontends.Tod

Show HN: 7-day jam became a 14-month build. satirical gun dating SIM (free)

It's political satire about American gun culture, toxic masculinity, and radicalisation pipelines, built by a distributed async dev team across multiple continents. The project started as a 7-day game jam entry and spiralled into 14 months of development. Whoops.It hit #2 on Steam's Upcoming Releases page before launch with 6,400+ wishlists.Some things that might interest this community:The scope creep from 7 days to 14 months is a case study in how small projects grow Unity, yarn We l

Show HN:AIP Protocol–Solving the agent revocation problem in distributed systems

I realized something uncomfortable while running agents in production:APIs authenticate the process making a request.But with LLM agents, the process no longer decides the request — the model does.So when an agent is prompt-injected or misaligned, authentication still succeeds. The system verifies who executed the call, not who chose it.Rotating keys or adding revocation checks doesn’t fix this. You’re still trusting the wrapper while the decision lives inside the model.The missing primitive isn
