Products that do what A Minimalist Coffee Bean Rating System Built with Go and Htmx does
Hey HN! After years of experiencing hit-or-miss coffee bean purchases, I built a simple solution to crowdsource coffee bean ratings. The problem is straightforward: buying new coffee beans is a gamble, and with rising prices, a bad bag is both disappointing and costly. The solution is a no-frills web app built with Go, HTMX, and Tailwind CSS. No accounts required, no JavaScript frameworks, just a simple 5-star rating system for coffee beans. Technical Stack: - Backend: Go - Frontend: HTMX + Tailwind CSS - No user accounts (intentionally) - Progressive web app I deliberately chose HTMX over a…

I brew coffee and I buy a lot of beans. I’m also a lazy person that doesn’t want to type in all the details in one of the available apps and track things to the grams. Luckily I found out that GPT-4o (free tier) is good enough to take a few photos I uploaded of a bag and parse it’s roaster, varietal, origin, tasting notes, roast date, etc. I tried with a dozen different bags and it works pretty well - even when it makes mistakes I can correct them with natural language conversation, which I enjoyed. Then I had to figure out storage. I don’t want to rely on the chat history / context as…

Hey there! I realized I was compiling a list of coffee shops with highly curated reviews in my personal notes: chair comfort, Wi-Fi networks and passwords, internet speed, noise level, bathroom cleanliness, etc... It worked fine for me, but when I wanted to share my list to some friends I realized the underlying problem. So I created Workffee for two reasons: 1. To allow me to save my reviews in a more convenient way and share them. 2. To connect with others who are interested in this information, and who knows, maybe share a coffee and a work session together eventually. I hope you like my…

Hi HN I built a fun little tool: It uses Groq’s LLaMA 3.3 + Puppeteer to analyze a website Then it roasts the design/content/UX with humor And finishes with 3–5 genuinely helpful improvement tips You can try it here: https://ai-roast-vert.vercel.app I wanted to: Practice fast idea-to-launch cycle (built in 2 days) Experiment with a viral-friendly product Monetize with a $0.55 pro version that gives a detailed roast + download Would love your feedback — on the idea, the tone, the usefulness — anything! Thanks in advance

Hi HN! We built RoastDB (https://roastdb.com) – think Discogs for specialty coffee. A searchable index of beans from independent roasters around the world. *The problem* We got into specialty coffee gradually. Whenever we tried something we liked — a washed Colombian, a natural Ethiopian — we'd save the bag. At some point we had drawers of empty coffee bags we couldn't bring ourselves to throw away. Our flow was simple: go to a cafe we liked, drink coffee, buy a bag of whatever they were roasting or stocking. Over time we started noticing patterns — we kept reaching for naturals,…

Primary link: http://hackerscoffee.org I thought Coder’s Coffee (http://news.ycombinator.com/item?id=4010355) was a great idea but disagreed with a few aspects of its execution (registration solely via linkedin, iOS app only, manual approval process, brittle: crashed every time I used it on my phone). I noticed the app had stopped working entirely last week, and went to the site (http://www.coderscoffee.com) to discover that the project seems to be no more. I re-implemented the concept, minus my grievances, in about 20 free hours I had last week (and also took the opportunity to make a…

I built a tool to roast landing pages with AI agents. I was gathering feedback from watching landing page roast videos, and figured out I could prompt LLMs to analyse a screenshot and roast based on the same criteria. It's not 100% accurate yet, but it has been really insightful when I've tested it on my own websites. Let me know what you think!

Hello again! I recently shared another device of mine (a focus timer based around an epaper display) and seeing all the positive feedback motivated me to keep building :) What you're looking at is a overcomplicated way of buying coffee a coffee scale that is connected to a coffee shop's (terminal.shop) API. You can order new coffee directly from the scale or even let it do that on its own once your bag starts to run low. It also allows you to weigh out single doses of coffee. Apologies if this sounds a bit too much like an advertisement for them, but that's the reason this is even a thing.…

For a while, I've struggled to really get into the Mobile ecosystem. With the duopology that Google (Android) and Apple (iOS) hold on the mobile ecosystem, it's very difficult for developers to build and maintain decent mobile apps, especially when you're a solo developer and UI/UX isn't exactly you're fore anyway. So I built (after some experiments with a friend @xuu) a little Go application framework that combines HTMX, DaisyUI/TailwindCSS and Service Workers with a little hack that works remarkably well that I've been able to build 3 quite nicely polished mobile apps (PWAs you…
