As answered by people managing CodePen and Shipd.
Shipd's answer:
Unlike traditional single-prompt generators that make one big guess, Shipd plans your app feature-by-feature, building and verifying each piece in a live in-browser preview. It connects directly to your existing codebase, reading your components and architecture so new features naturally match your exact stack.
Shipd's answer:
Most competitors generate output into a blank slate, forcing you to rewrite or refactor code to match your existing app. Shipd eliminates setup overhead by running real backend languages (Node, Python, Ruby, Go) and managed databases in cloud sandboxes with built-in authentication, allowing you to deploy directly to Vercel or push clean commits to GitHub without code lock-in.
Shipd's answer:
Shipd is built for software engineers, product managers, and fast-moving tech startups who want to rapidly prototype full-stack applications, generate production-ready features, or extend existing repositories without wasting hours on manual setup and integration.
Shipd's answer:
Shipd was born out of frustration with existing AI coding tools that treated codebases like blank pages. Developers spent more time fixing generated code that ignored existing design tokens, components, and conventions than writing it themselves. Shipd was built to read and respect existing repositories, delivering functional, pre-tested full-stack code that feels like it was written by a senior engineer on your team.
Shipd's answer:
Shipd leverages cloud-native micro-sandboxes with Docker and Vite dev servers for instant in-browser execution. On the frontend, it generates React, Vue, Svelte, and Vanilla JavaScript, while backend environments support Node.js, Python, Ruby on Rails, Go, Java, and C# backed by automated PostgreSQL databases.

> I vividly remember IE and many hacks to have css elements properly working in it… The common advice now is to only use CSS that is supported in the last two major versions of each major browser. You can check any css property's support... - Source: Hacker News / 2 months ago
