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!

Hi All This is my personal project that is an IDE and AI assistant for creating tailwind components and pages. You can chat to create designs, then make small edits yourself, and continue chatting to refine them. I am always working to improve the UX. I have a time limited demo page here: https://langcss.com/demo Please let me know what you think! Feedback is welcome. Tech wise, this just uses NextJS (Hosted on Docker) and Azure Open AI.

When we asked developers from large engineering teams, almost everyone is using Claude Code, Cursor, or Copilot. But adoption is still inconsistent. Some of us would have 15 agents running in Claude Code at the same time; some would still refuse to use any of them and write code manually. There's a fragmented AI development problem: - Five developers building similar features, and all of them start from scratch - No way to share "here's how we prompt AI to follow our architecture" - No trail of how the AI changes were generated - People leave the company, so does the their knowledge Aviator…

Hey HN, We’re two developers (co-founders) with a team of 20 who got tired of spending hours reviewing PRs, so we built Infinitcode.ai, an AI-powered code reviewer that: - *Summarizes PRs in plain English*: No more deciphering 1,000-line diff jungles - *Catches more than bugs*: Security holes, performance pitfalls, code smells, even typos (yes, we’ll flag “vurnerabilities” and vulnerabilities) - *Zero onboarding*: Works instantly—no “let me learn your codebase for weeks” nonsense. Why we’re posting: We’re in alpha and need brutal honesty. Roast our tool, mock our UI, or tell us why AI will…

I’ve been experimenting with embedding an Claude Code/Cursor-style coding agent directly into the browser. At a high level, the agent generates and maintains userscripts and CSS that are re-applied on page load. Rather than just editing DOM via JS in console the agent is treating the page, and the DOM as a file. The models are often trained in RL sandboxes with full access to the filesystem and bash, so they are really good at using it. So to make the agent behave well, I've simulated this environment. The whole state of a page and scripts is implemented as a virtual filesystem hacked…

While Cursor has already revolutionized coding, you can still configure it to perform even better based on your language and framework. That's why we created Cursor Directory, a collection of the best cursor rules for your framework and language from the community. It's fully open source and you can contribute to it by submitting your own rules. Just copy and add a .cursorrules file to your project root! Let me know what you think!

The answer is simple: the more "prescriptive" you are with instructions for Claude, the worse your output. The reason is that Claude tries to pattern match - it's been trained on thousands of safe UI patterns, which is why when you ask for "a modern dashboard" it doesn't really think about the problem space; it just defaults to whatever safe design pattern it can whip up at the time. I've been working on a Claude Code skill to combat generic UI output, and I tried different approaches like being very detailed with my personal visual style, e.g., the type of alpha values to use for borders,…

Hi y'all. Been working on something that should've been made a long time ago imo. It compiles codebases into O(1) hashmaps that the agent queries to discover the structure of your code/answer questions/write code. It also does complete static analysis checks on any writes the agent makes. Don't take my word for it though. Here are the benchmarks: https://benzi.fly.dev/benchmark. on 2/20 tests, Claude Code (mostly Sonnet on one task) regressed or timed out. Benzi didn't because of course, it has a map it can query and not get lost in the sauce. On the other 18 it…

I built ARM (AI Rules Manager) to solve a problem that's been bugging me: managing AI rules across projects is broken. If you use Cursor, GitHub Copilot, or Amazon Q, you know how powerful custom rules can be for guiding AI behavior. But right now, everyone just copies `.cursorrules` files around manually. Once copied, they're orphaned – no updates, no version control, no way to know if changes will break your AI's behavior. ARM treats AI rules like npm packages. You can: - Install versioned rulesets: arm install awesome-cursorrules/python - Connect to Git registries like…

Hi HN, Zidan here. I’ve been experimenting with AI-assisted debugging and noticed a recurring gap: most tools optimize for agent-led exploration (ex: giving claude code a browser to click around and try to reproduce an issue). But in many cases, I've already found the bug myself. What I actually want is a way to hand the agent the exact context I just saw - without retyping steps, copying logs, or hoping it can reproduce the behavior. So we built FlowLens, an open-source MCP server + Chrome extension that captures browser context and lets coding agents inspect it as structured, queryable…

Hey HN! I'm Andrew, one of the creators of Glass, a copilot for Next.js and React developers. Glass appears as a chat bar on your locally running Next.js server, and you can tell it to make changes like "build a dashboard" or "add a login button". Glass makes the changes to your sourcecode in real-time. Our goal with Glass is to automate away the easy but slow parts of frontend development, like locating the right file to edit, writing tailwind by trial-and-error, and copy-pasting boilerplate from Claude and other tools. We want to let you do all the tedious work entirely from your browser.…
