VibeCheck is a content management system, or CMS, that you operate by chatting with an AI assistant instead of clicking through an admin panel. The idea is straightforward: you type a sentence describing what you want on your website, the system translates that into validated content, commits it to a GitHub repository, and the site redeploys automatically. The whole cycle takes about 30 seconds. The system is built as a monorepo with three parts. One package defines a schema, meaning a set of rules describing what content can look like. A second package is an Astro-based website that reads content files and builds static HTML pages. A third package is an MCP server, a type of connector that lets Claude access tools to create, update, or delete pages. Because the site and the MCP server share the same schema, any edit the AI attempts is validated before it lands in the repo. If the content would break the site, the change fails without affecting the live pages. Content is stored as YAML files rather than raw HTML. Pages are made up of typed sections: heroes, feature grids, pricing tables, call-to-action banners, forms, and a single richtext section type for situations where HTML is needed. Keeping most content in typed data means AI-generated edits cannot accidentally introduce broken markup. There are two ways to use VibeCheck. If you run Claude Code locally with the repo open, you can ask Claude to edit pages directly and the schema validates at build time. If you run the MCP server, you can connect to it from claude.ai or the Claude desktop app and edit the live site from anywhere. Publish modes let you either open a pull request for review or commit directly to the default branch. The project deploys as static output to Vercel, Netlify, or Cloudflare Pages. A public live demo lets visitors try editing the site themselves. The project is MIT-licensed.
