Grafly.io – Free online diagramming tool
Hey, I'm Nenad. I built Grafly (https://grafly.io) because I kept reaching for different tools just to sketch out a quick architecture diagram and hating either the UI, color schemes, usage patterns or that I had to log in, or have my doodles stored on someone's server. It's a React/React Flow app that runs entirely in the browser meaning that everything saves to localStorage, nothing leaves your machine. You get basic shapes, AWS/GCP icons, edges with waypoints and shareable URLs that encode the whole diagram in the query string (no backend, just LZ compression). There…

What it does
Grafly is a free browser-based diagramming tool. In my view diagrams are purpose-driven tools for communication and clarity. I've tried to accomplish this with Grafly. Create flowcharts, generic diagrams for stuff (we all do stuff), AWS architecture diagrams, GCP cloud diagrams and more. No account needed, everything saves locally, you can share diagrams via smart URLs and it's fully open source.

A gallery of graphs built with React and D3.js2023 · react-graph-gallery.com · ▲297Many JS libraries exist to build graphs on the web (Vega, chartJS, Plotly...). They allow to make charts quickly. But you lose flexibility: you're limited by the options they offer. I just created a gallery with hundreds of graphs made with d3.js and React. - Examples are split by graph types - They all come with explanation and code sandboxes - Gradual complexity to ease the learning curve It took me ages to create this project! Feedback welcome!
I reverse engineered top websites to build an animated UI library2025 · reverseui.com · ▲156Looking at websites such as Clerk, I began thinking that design engineers might be some kind of wizards. I wanted to understand how they do it, so I started reverse-engineering their components out of curiosity. One thing led to another, and I ended up building a small library of reusable, animated components based on what I found. The library is built in React and Framer Motion. I’d love to hear your feedback

Talanoa▲346Hi 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…
