21st.dev▲1,211I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!

v0 for iOS▲655While using iTerm2 while busy working today, I once again felt frustrated by having too many tabs and losing the overall perspective of what tasks were in progress. So, I used v0 + Opus 4.5 to envision an ideal Terminal tab management UI in my mind, to demonstrate the best way for me to manage tabs in the terminal. What do you think?

We’ve been working on Vaev, a minimal web browser engine built from scratch. It supports HTML/XHTML, the CSS cascade, @page rules for pagination, and print-to-PDF rendering. It even handles calc(), var(), and percentage units—and yes, it renders Google.com (mostly). This is an experimental project focused on learning and exploration. Networking is basic (http:// and file:// only), and grid layouts aren’t supported yet, but we’re making progress fast. We’d love your thoughts and feedback.

Hey folks, I'm building a free and open-source monorepo template for "production-grade Next.js apps". Basically everything you need to go from "new idea" to "Series A level product" very quickly. It's almost at 500 stars on GitHub so I thought I might share it here. It comes pre-configured with analytics, auth, a blog, dark mode, transactional email, feature flags, monitoring, ORM + database, payments and heaps more. It's quite opinionated but very fast and very neat. I hope it helps you make something awesome.

Once UI 1.5▲299When I started my career and built my first design system, I was beyond excited. It took a lot of iterations, learning and 6 months of work to launch it internally. In the next job, I did it again, then at the following job, again… And no matter which company I worked for, 80% of the design system was the same. I’ve decided to work full-time on the design system I’ve always wanted, and today I’m launching and open-sourcing it. You can use it to build Next.js apps faster, and I’ve designed it in a way that it’s hard to go wrong with it: you can choose any settings, and you’ll end up with a…

Modo▲148I’ve built hardware projects for years, and the gap between “I want X” and “parts ordered, files ready to print” always took weeks. Modo compresses that. Describe what you want (e.g. “a portable CO2 monitor with a display and buzzer”) and it generates: - A bill of materials with real components (MPNs, not hallucinated parts) - A printable enclosure generated from actual part dimensions - Wiring diagrams, firmware boilerplate, and assembly instructions - Design validation (power budget, pin conflicts, mechanical fit) Everything streams in real time as each phase completes. The key idea is…

SvelteShip▲122Hey, I built svelteship after long hours trying to find the right tech stack and integrations for my apps. I created it for myself and others with documentation so whenever an idea comes to mind you can get started quickly. It is a batteries-included boilerplate so you can focus on your apps. Any feedback is welcome!

This has been an experiment to see if I could create everything using scripts and AI. If AI couldn't do it I'd get it to create the code such as API calls and so on. This websvg.com site was completely created using these AI tools. Including the DNS being applied, the Cloudflare Pages were automatically set up and the the web site was a Svelte 5 application generated by v0.dev and Cursor. Every image was generated in Midjourney and converted to SVG. I have now taken all of these scripts and can create a similar landing or directory site in less than a minute, provided I have the data. Anyway…

This is a personal project I've been working on and off for the past few years. It's a set of tools that have allowed me to prototype quickly small (and increasingly bigger) kernels, and create userspace programs to interact with them. Supports riscv64, amd64 and i386. The intel port has been tested and used on real hardware, from big dual-socket Xeon machines to an old X220. It is all C, I have plan to make rust bindings for the kernel library. But again, they're plans at this stage. Porting to new architectures is relatively simple, a basic port to riscv took me a couple of weeks of…

Made an ARM Thumb CPU from scratch in a digital circuit simulator for fun and decided to push the joke a little further and run real stuff on it, like a Web server, a Scheme interpreter, a MIDI player, and a VT100 emulator. This is basically a how-did-we-get-here blogpost, it's my second one of this kind, I'd love any feedback you might have.
