seite

You already have Claude Code. seite gives it something to work on.

seite agent "write a post about our v1 launch — here are the notes: ..."
seite agent "redesign the homepage hero, we just pivoted to B2B"
seite agent "create changelog entries for these release notes: ..."
seite agent        # interactive session

The agent reads your config, your templates, and your existing content before writing anything. Output lands in the right directory with the right frontmatter. You review a diff and ship it.

No new subscription. No new UI to learn. No new commands. Just the Claude Code subscription you already have — now it can manage your whole website.

curl -fsSL https://seite.sh/install.sh | sh
seite init mysite --title "My Site" --collections posts,docs,pages
cd mysite && seite serve

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 .md copy 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

Agent

seite agent spawns Claude Code with full site context — config, content inventory, templates, and available commands. No API keys, no setup. Uses your existing Claude Code subscription.

seite init generates .claude/CLAUDE.md with your site's full schema so the agent is oriented before it writes a single character. Output lands in the right directory, with the right frontmatter, following your conventions. You review a diff and ship it.

seite agent "write a post about our v1.2 release — here are the notes: ..."
seite agent "rewrite the homepage hero, our positioning shifted to B2B"
seite agent "generate docs stubs for each CLI command"
seite agent        # interactive session

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.

Features

• 6 bundled themes — default, minimal, dark, docs, brutalist, bento — or generate a custom one with seite theme create "coral brutalist with lime accents"

• 6 collection presets — posts, docs, pages, changelog, roadmap, and trust center

• Multi-language — filename-based i18n with per-language URLs, RSS feeds, sitemaps, search indexes, and hreflang tags

• Image pipeline — auto-resize, WebP conversion, srcset/<picture> elements, lazy loading

• Deploy anywhere — GitHub Pages, Cloudflare Pages, Netlify with guided setup, pre-flight checks, and --dry-run

• Analytics — Google Analytics, GTM, Plausible, Fathom, Umami with optional cookie consent banner

• Shortcodes — youtube, vimeo, gist, callout, figure built-in, plus user-defined templates

• Multi-site workspaces — manage multiple sites from one directory with unified dev server

• Self-update — seite self-update fetches the latest release with SHA256 checksum verification

Contributing

seite is early and issues, PRs, and feedback are genuinely welcome. Especially useful:

• Bug reports with a repro case (even a minimal seite.toml + content file)

• New theme ideas — open an issue first to align on direction before building

• Docs improvements — if something confused you, it'll confuse others

• Real-world usage — if you build something with seite, share it

git clone https://github.com/seite-sh/seite
cargo build
cargo test        # 331 tests (139 unit + 192 integration)
cargo clippy      # must be zero warnings
cargo fmt --all

Open an issue before starting a large PR — saves everyone time.
