I'm working on a mockup and demo creation tool straight on your phone so you can build in public easily.

Built a free toolkit that grew into 5 sites, 200+ tools, no signup required I started this a few days ago to build a free invoicing tool for freelancers because everything I found was gated behind a signup wall or a "free trial." It turned into a small portfolio of 5 sites, each aimed at a different kind of solo operator: Ledgerline: invoicing, contracts, and tax calculators for freelancers Rentline: rent increase letters, late fee calculators, and lease guides for landlords Sellerline:

I vibe coded a demo for grading, not in a great shape but it's fun to play a bit.

KiCad, a PCB EDA suite is now working in a browser, you can try it at the link, there's a demo project or you can bring your own. Firefox is best, Chrome is good, Safari is "working". We’re Emergence Engineering, a dev shop from Hungary, mostly working with rich text editors, CRDTs. PCBJam started as my (Viktor, CTO, ex-electrical engineer) hobby project but as time went on I put more and more energy into it, and a product started shaping up in my head, in the last few months we’ve started to focus on this project a bit more, and this is the first MVP~ish result. This project is a ton of fun, ton of learning, ton of improvements over improvements: - I thought there must be ways to emulate the PCB canvas OpenGL code on the web. And yes, there are a lot of ways, all of them very buggy. Turns out it’s faster to just write WebGL code that works with KiCad’s Graphics Abstraction Layer if you add the right intermediate debugging steps. I (with Claude) implemented the features and compared

Why spend hours making demo videos? Paste a URL and let AI do it These days everyone is building products, but promoting them is a completely different challenge. Recording demos, editing videos, adding captions, and making content for Shorts, TikTok, Reels, or ads takes a lot of time. So I built Screenzy.pro. Just paste your product URL, and it automatically creates product demo videos that explain what your product does. It works well for social media content, launch videos, tutoria

by @golnik is the best vibe-coded software project I've seen, both in its aesthetics and the difficulty of its accomplishment. You can see the finished output of his work here:
