Managing a startup's web presence has always felt disproportionately painful. A CMS for the marketing site. A separate docs platform. A blog tool. A changelog app. Each with its own login, its own subscription, none of it connected to how you actually build the product.
Meanwhile your team ships software with AI assistance every day. seite closes that gap. One CLI tool for your landing page, docs, blog, changelog, and roadmap — managed with the coding agent you already use, with no new subscriptions required.
It was built with Claude Code. This site is managed with Claude Code. That's the point.

Why seite
Most static site generators produce HTML and stop there. seite builds for three audiences at once:
- Browsers get pages with full SEO metadata, Open Graph, Twitter Cards, and JSON-LD structured data
- LLMs get
llms.txt,llms-full.txt, and a.mdcopy of every page for direct consumption - AI tools get a built-in MCP server that exposes your entire site as structured resources
All from Markdown + YAML frontmatter. No JavaScript runtime. No build dependencies. One binary does everything. 331 tests, 139 unit and 192 integration.
AI integration
This is where seite is different from every other SSG.
Agent
seite agent spawns Claude Code with full site context — config, content inventory, templates, and available commands. No API keys, no setup. It uses your Claude Code subscription directly.
The agent reads your schema, your templates, and your existing content before it writes anything. The output lands in the right directory, with the right frontmatter, following your conventions. You review a diff and ship it.
MCP server
seite mcp runs a Model Context Protocol server over stdio. Claude Code auto-starts it via .claude/settings.json, generated by seite init. Any MCP-compatible AI tool can use it.
Resources — seite://docs, seite://config, seite://content, seite://themes, seite://trust
Tools — seite_build, seite_create_content, seite_search, seite_apply_theme, seite_lookup_docs
This means your AI tool doesn't just have read access to your site — it has a structured interface to build, search, and modify it.
LLM discovery
Every build generates llms.txt (summary) and llms-full.txt (complete markdown) for LLM indexing, plus a .md copy of every page. Multilingual sites get per-language versions. Traditional SEO and GEO handled in one pipeline, automatically.
