I use a ton of 3D Files as I love 3D printing in my spare time and I usually exchange them over Gmail and store them in Google Drive etc.. Google does not have a 3D Preview of files so I've built a small Google Workspace Addon that opens the file into a clean "Google like" web app that supports most files. Other solutions existed but they were full of ads and looking absolutely terrible. It got a bit of traction (around 400 users) on the store so thought I would share it here! Would love to have feedback! Each file is treated purely in the browser for maximum privacy

Hey HN! I’m Gabriel, and I’m excited to share a project I’ve been working on for the last few years. Flowcode is a visual programming platform that tries to combine the best of both worlds (code and visual). Over the years I found myself repeatedly drawing architectures and logic. It was always my dream to just press “run” instead of having to write them in code afterwards. But none of the visual tools I found were flexible and transparent enough for building real products. I think that visual programming fits perfectly with modern backend dev tasks that revolve around connecting different…

Hi all, I'm a PM by day who taught themselves to code over COVID. One of the things I enjoyed during that process was learning how to make basic games in Unreal Engine using Blueprints. I found visual scripting was such an intuitive way to express what I call "mid-tier complexity" logic and I felt there really wasn't a great equivalent for the web - so I built one over the last few months and this is my MVP. Tools like Zapier etc are great and easy to use, but they're heavily limited when it comes to expressing any kind of complex logic or trying to follow coding principles like DRY. On the…
