The best way to build websites with Claude Code
sitemd is a static site generator / website building toolkit for AI coding agents like Claude Code.
It's a complete agent-driven framework with CLI, dev server, skills, guardrails, best practices, and one-line integrations for essentials like SEO, analytics, content generation, doc writing, user login, content gating, dynamic data + detail pages, and more.
It's a site-building superpower for Claude.
Install sitemd for Claude Code
Scaffold a fresh sitemd project and open it in Claude Code:
npm i -g @sitemd-cc/sitemd
sitemd init my-site
cd my-site
claude
Claude Code detects the sitemd project, loads the skill, and you're building.
Already have a sitemd project on disk and want the Claude Code marketplace integration? In any Claude Code session inside your project, run:
/plugin install sitemd
That installs the sitemd plugin from the Claude Code marketplace and exposes the full sitemd toolset to your agent. The plugin expects you to already have sitemd installed globally (npm i -g @sitemd-cc/sitemd). Use sitemd init above for a fresh start.
Plugin source: .claude-plugin/ (plugin.json, marketplace.json) on the public sitemd repo.
Why use sitemd with Claude Code
Claude Code is amazing at writing code, and will already happily build websites from scratch. Adding sitemd makes the process faster and reduces friction.
sitemd is a super-efficient toolkit for coding agents to build websites. It ships with:
- A full suite of CLI commands for pages, settings, content generation, SEO, deploy, auth, and more — Claude calls them directly, no manual file editing required
- A full suite of skills that map to the work Claude is doing:
/write,/launch,/deploy,/seo,/kickstart,/clone, and more - A complete framework under the hood: auth, gated content, forms, deploy targets, image handling, dynamic data, theming, premium modules — none of which you and Claude have to invent
- Markdown all the way down — every page, every setting, every navigation file is human-readable
.md. Claude reads markdown natively, edits it confidently, and never has to reverse-engineer an external build system
Why not just prompt Claude to build a site from scratch?
sitemd is a site-building superpower for Claude. It helps Claude build a consistent working site quickly by skipping all the scaffolding that's already baked-in to sitemd. sitemd is still very flexible and customizable, so you and Claude can still build sites however you want. sitemd also ships with one-line integrations for essentials like SEO, analytics, content generation, doc writing, user login, content gating, dynamic data + detail pages, and more that would take considerable time for you and Claude to build from scratch.

Build your first site with Claude Code
After install, in any Claude Code session inside a sitemd project:
"Build me a documentation site for my SaaS product"
Claude Code calls sitemd status, then sitemd site-context to learn the conventions, then sitemd pages create-batch to scaffold pages, then sitemd content validate to check quality, then sitemd deploy when you confirm. The skill surfaces the right context as the agent works. You watch the dev server preview update live.
You can also run an agent skill directly:
/kickstart a portfolio site for a freelance designer named Mira
That spins up a complete first-draft site — pages, navigation, settings, theme, copy — from a single sentence.
