Nimbus▲89Hi HN, I'm Anil. Nimbus is a desktop browser with an AI agent built into it. The UX is shamelessly inspired by Claude Code: a chat bar at the bottom, an agent log above it, and the webpage itself when its needed. This is mainly a UX experiment for me. And also the reason it isn't a Chrome extension: once you have a chat bar that understands intent, the URL field is redundant. You shouldn't have two places to tell the browser what you want. I didn't want to bolt an agent onto an existing browser's chrome and end up with duplicated controls everywhere — I wanted full freedom to redesign the…

Hey HN, We’re two developers (co-founders) with a team of 20 who got tired of spending hours reviewing PRs, so we built Infinitcode.ai, an AI-powered code reviewer that: - *Summarizes PRs in plain English*: No more deciphering 1,000-line diff jungles - *Catches more than bugs*: Security holes, performance pitfalls, code smells, even typos (yes, we’ll flag “vurnerabilities” and vulnerabilities) - *Zero onboarding*: Works instantly—no “let me learn your codebase for weeks” nonsense. Why we’re posting: We’re in alpha and need brutal honesty. Roast our tool, mock our UI, or tell us why AI will…

Hi HN, I built Reviewskits because of a recurring frustration I faced while working for a web agency in Switzerland. Our designers created beautiful, pixel-perfect layouts, but when it came to testimonials, we were stuck with rigid, pre-made widgets from tools like Senja or Trustpilot. Hacking them with CSS to match our UI was a nightmare. When we looked at their API pricing to build our own components for 100+ clients, the cost was astronomical ($90 to $300+/mo). Later, as an indie dev building my own SaaS, I simply couldn’t afford those prices. So I built Reviewskits: High…

I’ve spent the last 2.5 months building a product that runs LLM-powered code reviews on my pull requests — and I just launched it. The tool is built specifically for solo developers. You install it on your repo, trigger a scan by creating a pull request, and it leaves structured review comments using OpenAI under the hood. Funnily enough, I used the dev version of this app to review its own pull requests while building it. It helped me spot bugs, simplify structure, and keep quality high — all with minimal need for another human in the loop. Things I want to try out in the next months : -…

I’ve always found it funny how simple feedback widgets end up as $20–$30/month products. The tech is dead simple, infra is cheap, and most of us here could rebuild one in a weekend. So as a “principle experiment” I built my own today as a side project and priced it at 1 dollar. Just because if something is cheap to run and easy to replicate, it should be priced accordingly, and it’s also fun marketing. 1$ feedback tool. Shipped today, got the first users/moneys today, writing this post today. Side Sunday project, then back to the main product tomorrow.

As a product manager I've used different feedback tools and almost never liked the design and experience of the widget. And pricing of some existing tools is just way too high, at least for indie makers or small businesses ($35 for 100 responses...). That's why I've launched Freddy Feedback (today!). You can find it on www.freddyfeedback.com. Curious to hear your feedback (very meta ;-)).

Backsy.ai▲11I got tired of endless survey forms that nobody wants to fill out. So I built Backsy, an AI-powered feedback tool where people can just type (or speak) their thoughts, and AI auto-scores the relevant product attributes—no need for structured forms or manual analysis. Backsy also works with bulk feedback (think scraped Reddit threads, support emails, app reviews, etc.), making it easy to extract trends from raw user comments. Would love to hear your thoughts—especially if you’ve struggled with feedback fatigue or collecting useful insights at scale!
