Hello everyone! I'm a solo developer who's been doing UI/UX work since 2007. Over the years, I watched design tools evolve from lightweight products into bloated feature-heavy platforms. I kept finding myself using a small amount of the features while the rest just mostly got in the way. So a few years ago I set out to build a design tool just like I wanted. So I built Vecti with what I actually need: pixel-perfect grid snapping, a performant canvas renderer, shared asset libraries, and export/presentation features. No collaborative whiteboarding. No plugin ecosystem. No enterprise…

OpenUI▲322Thesys just open-sourced their generative UI rendering engine. Interesting timing given where Google a2ui and Vercel's json-render are headed. The difference worth noting: a2ui and json-render both treat JSONL as the contract between the LLM and the renderer. Thesys is betting that's the wrong primitive. Their engine uses a code-like syntax (OpenUI Lang) instead — LLM writes it, renderer executes it. The argument is that LLMs are fundamentally better at generating code than generating structured data, so you get cleaner output and ~67% fewer tokens. The broader vision seems to be a…

Xano▲390Hi HN — I’m Daniel, DevRel at Xano. Three years ago, Xano started as an internal tool at a software agency. We were rebuilding the same backend infrastructure for every client—auth, databases, APIs, file storage, scaling, security—over and over again. To save time, the team built a platform that could generate production-grade backends in days instead of months. That internal tool evolved into Xano, which now powers products used by both startups and large enterprises. Companies like Deriv, an online trading broker with over 3 million customers, use Xano to ship features faster without…

Design Rails▲211Hey HN, we're building Design Rails. It's a chat-based brand builder. You describe your project, iterate with an AI designer, and walk away with a logo, color palette, typography, and style guide - all formatted as specs you can drop into your project for Claude Code, Cursor or whatever you're coding with. Free tier gets you a full logo (PNG) and basic palette. Paid tier ($49 one-time) - everything you need for your next project - full coding-agent ready specs, SVG logos, icon variants, etc. Built with Next.js, Vercel AI SDK, and Inngest for the async generation jobs. Would love to hear your…

This is a recent addition to Vexlio which I think the HN crowd may find interesting or useful. TL;DR: easy creation of interactive diagrams, meaning diagrams that have mouse click/hover hooks that you can use to display pop-up content. The end result can be shared with a no-sign-in-required web link. My thought is that this is useful for system docs, onboarding or user guides, presentations, etc. Anything where there is a high-level view that should remain uncluttered + important metadata or details that still need to be available somewhere. You can try it out without signing up for…

Hey, Jared Palmer (creator of this playground) here. Really excited to ship this. I’ve been building this over the past few weeks to compare LLMs from different providers like OpenAI, Anthropic, Cohere, etc. At Vercel, I manage our Frameworks division (including Next.js, Svelte, and Turbo) and wanted to also dogfood some of the latest features in a slightly larger application. This playground takes a lot of inspiration from https://nat.dev and is built on Tailwind, ui.shadcn.com, and some upcoming Vercel products we’re announcing soon. We’re going to continue adding models to…
