Site Settings
All settings are in the Settings tab of your site's dashboard page.
General
Site name — displayed in the browser tab, nav bar, and social sharing previews.
Slug — the URL path for your site (sidian.app/s/your-slug). Cannot be changed after creation.
Custom domain — serve your site from your own domain. See Custom Domains.
SEO & Sharing
Default social image — the og:image used when a note doesn't specify its own cover in frontmatter.
Prevent search engine indexing — adds noindex to every page. Useful for private sites where you don't want Google to index any leaked URLs.
Show table of contents — adds a sticky sidebar TOC to notes with two or more headings.
Security
Site password — set a password that visitors must enter before seeing any content. The password is set once and verified via an HTTP-only cookie (valid for 30 days).
You can also set passwords at the folder and note level — see Access Control/Passwords.
Appearance
Logo, favicon, accent colour, custom CSS, and custom JS are configured in the Appearance tab.
See Appearance/Branding & Theming.
Frontmatter fields
The Settings tab includes a Frontmatter fields section that lists every frontmatter key found across your vault. All fields are shown on the published page by default. Check a field to hide it from visitors.
Meta-tag fields (description, image, cover) still apply to <head> regardless of the display setting — hiding them removes them from the visible panel only, not from search engine and social previews.
Obsidian Plugin
The Sync tab shows:
- Connected devices and their last sync timestamp
- A re-render button to reprocess all stored files through the latest markdown pipeline
API keys are managed in Account settings, not the vault dashboard — a single key works across all your sites.
