Products that do what DiffCAD, a FreeCAD workbench to review model changes like code does
I'd like to share a new workbench I've been working on called DiffCAD. Coming from a software engineering background, not having the ability to properly diff my CAD model changes was driving me crazy. This project scratches my own itch, and maybe someone elses', too! I'm open to feedback, ideas, and contributions. Cheers!

My friend and I have been working on Arcad for some months now. It's a free browser-based parametric CAD tool aimed at hobbyists and makers. It has editable feature history, solid modeling powered by OpenCascade, STEP export and touch controls for tablets, although it's primarily made for PC use. Everything runs in the browser and you can try it without creating an account or installing anything. Currently in beta although we feel like it's ready for a full launch. Any feedback is appreciated! Link: https://app.arcad.studio Docs: https://www.arcad.studio/docs

I had a hard time figuring out CAD software like Fusion, OnShape, etc., and decided to go about making my own CAD modeling software that I can "program" my models similar to how I think about them in my head. I used Cursor to write like 95+% of this, giving it my YAML examples and making it implement the actual code to make those work. Currently 100% self-hosted, and it is just a static HTML/CSS/JS, so it might just work without running npm at all. Very few features working currently, basically just modeling a few primitive solids, and boolean operations.

I built this tool a couple days ago to temporarily hide your prints & comments. I wanted to focus on the core logic without having to constantly delete/add prints and comments. Lmk if you like it ;)

The main goal of this was to be able to not just run multiple Claude Code sessions at once, but actually manage them and keep track of what I was doing. Sometimes this is multiple attempts on the same task, sometimes I work several tasks at once. Really I was just sick of twiddling my thumbs waiting for the coding agent to finish, and I wanted it to be easy to work on/review/test another change while I waited.

process demo - https://i.redd.it/fbhlwsq1gcmg1.gif render demo - https://i.redd.it/smddwtryhcmg1.gif I love making creative software. I spent a few years making pixel art software but recently have gotten into 3d animation and 2d animation and really wanted a way to realize crazy ideas. Blockbench didn't feel quite right, spline is super well made but felt catered too much to just idle website animations, and I really didn't want to fall down a master class in Blender just to make some silly stuff. While I'm definitely not discounting Blender's literal…

My focus has been shifting towards the ML alignment space recently, and in particular the ability to translate large transformer models into human understandable circuits and algorithms. This problem potentially isn't solvable, but it is one that some groups have had success with after large amounts of effort. In attempting to address this issue, I've been developing Transpector. A tool scaling up and reducing the barrier to entry of techniques that these teams have been showing success with. Techniques aiming to understand the internal mechanics of the model. Currently this tool is focused…

Hi there! I'm building Diagrammatic, a simple and free online tool with the ambition to become a community for diagrams-as-code enthusiasts. Currently, it supports Mermaid, PlantUML, Dot (Graphviz), Vega-Lite, and Typogram, but I'm looking to add more languages. Please let me know if there's a particular one you use. I'd appreciate any kind of constructive feedback as well. Thanks in advance!

Hi, all I worked on this tool a couple of months. I always had trouble creating a logo for my next project so I decided to automate it. Appreciate any feedback. Cheers, Dan

Hello everyone, A couple of months ago I was introduced to Excalidraw and fell in love with it instantly. The only thing I didn't like was that I couldn't easily save my whiteboards and had to put everything in one whiteboard which started to lag my PC after a while. So I made ExcaliHub. It's exactly as it sounds: a hub for Excalidraw. It's free, open source, and I aim to keep it that way. Thanks in advance for any feedback!

Fully leaned into vibe coding this time around. Started on v0, at some point ejected into running locally (getting v0's exported folder to run locally was a challenge), then iterated with Cursor over the course of a few hours. Really neat how much can be accomplished just conversationally these days.

Hi HN, I’ve spent the last decade building hardware products like humanoid robots, 3D printers, and self-driving tractors. I needed a tool to navigate technical documents faster, so I created one with friends. This tool helps with component search, cross-referencing, comparison, and debugging. We’d love your feedback, whether you find it useful or not. Thank you! Try it here: www.convergelab.ai

Hey HN! I develop browser extensions, I suck at web design, and I've been exploring AI/LLMs. With my new found free-time since dropping work hours, I've developed a Design Copilot browser extension [0]. It does what it says on the tin - you choose a part of your website and the tool gives you instant expert design feedback - "change this font to that, add this much whitespace, use brighter colours .... etc" The tool is completely 100% free to use, its powered by bringing your own AI API Key, and the current LLM it uses is Google Gemini 1.5 Pro. I've yet to hit the free rate-limit and I…

I got the idea of [mindmap.so](http://mindmap.so/) out of my own frustration of managing my personal notes in Notion and Miro in parallel. I have built it 3 months back on top of excalidraw, posted it in Reddit a couple of times, and never looked back (was using it only for personal use). Little did I know that the small and nimble tool that I created has crossed 2000+ users (was so surprised when I saw the dashboard last week). It was all organic and word of mouth . Having 2000+ users trusting a product is no easy feat. That’s when I thought may be I should put some more…

Hi HN, I’ve been tinkering with this for a while and finally have it in a decent state. It’s a plotter robot that draws caricatures from photos. I trained a diffusion model (Flux Kontext LoRA) on caricature images, 3D-printed a Sharpie mount for my Ender 3, and hacked together a pipeline that goes photo → caricature → G-code. After a lot of trial and error it’s working pretty well, and I put up a little site where you can try it out. Happy to answer questions or hear any feedback. Thanks!

VSCode was my daily driver for years, but once I started running several coding agents across multiple projects at the same time, it got in the way. One workspace with terminals in the bottom tray, no idea which agent was doing what and I found myself needing all the code editing tools less and less. So I built my own IDE around that workflow. Terminals are a first-class citizen, every project stays alive in the background with visual statuses. Close the workspace and come back weeks later, everything is still in its place. I've been using it for weeks and it's a big productivity boost. The…

Hi everyone! I built this because I wanted a little bit more organization around my Claude sessions, worktrees and plans while staying in the terminal and not relying on another SaaS tool. Since it's a command line tool, the added bonus is that Claude can use `td` directly. The td calendar was just a fun add-on but the Claude session stats have been pretty interesting! Let me know what you think!
