Build Modes
sitemd has two modes: trial (unactivated) for free localhost development and activated for deployable builds. Trial gives you the full experience to evaluate the product. Activated requires a paid account and produces clean, standalone HTML output.
Trial Mode (unactivated)
Trial mode is active when the site has not been activated. It's the default for new projects.
What you get:
- All features work on
localhost:4747— pages, themes, cards, embeds, images, forms, analytics, auth, data, gating, SEO - Live build sync with hot reload
- Dev panel for in-browser editing
- MCP server integration
What's different from activated:
- Output is memory-only — no
site/directory written to disk - A "SITEMD TRIAL (UNACTIVATED)" banner appears on every page
- The sitemd badge is always visible in the footer
sitemd buildandsitemd deployare not available
No authentication required. You don't need a sitemd account to use trial mode.
Activated Mode
A site is activated after running site activation. Activation permanently locks your site's identity fingerprint and consumes one site slot on your account.
This requires a paid sitemd account. Run sitemd auth login to authenticate. Every build and deploy calls the sitemd API to verify your site identity — network access is required.
What you get:
- Clean HTML output to
site/directory — host anywhere - No dev banner. Badge shown by default but can be hidden
- Full SEO output: sitemap.xml, robots.txt, llms.txt, OG image files, favicons
- Image optimization with WebP generation, media hosting via CDN, card auto-images
- Deploy with
sitemd deployto Cloudflare Pages, Netlify, Vercel, or GitHub Pages
All features work in both modes
Every feature works identically in trial and activated. The dev server renders everything — there are no placeholder cards or degraded features during local development.
| Feature | What it includes |
|---|---|
| SEO | OG tags, canonical URLs, Twitter cards, JSON-LD structured data |
| OG image generation | Satori/Sharp rendering of per-page open graph images |
| Forms | Webhook submission, field types, multi-page forms, conditional logic, honeypot anti-spam |
| Analytics | Google Analytics, Plausible, Fathom, Umami, Simple Analytics, PostHog, Matomo, GTM, ad pixels |
| User auth | 5 provider adapters: custom API, Supabase, Firebase, Clerk, Auth0 |
| Dynamic data | 4 provider adapters: Supabase, Firebase, Airtable, REST API |
| User-type gating | Role-based access control for pages and inline sections |
| Image optimization | Build-time resize, compression, WebP generation, <picture> tag injection |
| Media hosting | R2/S3 CDN sync at build time, HTML /media/ URL rewriting to CDN prefix |
| Card auto-images | Auto-generated gradient/illustrated card images |
| Deploy | Cloudflare Pages, Netlify, Vercel, GitHub Pages upload integrations |
| Badge removal | Option to hide the "built with sitemd.cc" footer badge (shown by default, even when activated) |
| Email templates | Transactional email compilation |
Activated-only outputs
These files are only written to disk during activated builds (sitemd build or sitemd deploy):
sitemap.xmlrobots.txtllms.txtandllms-full.txt- RSS feed XML files
- Compiled email templates (
_emails.json) - Search index (
search-index.json) 500.htmlerror page
The features that generate these outputs (SEO, feeds, email) still render in the dev server — they just don't produce standalone files until you activate.
Site slots
Site slots control how many sites you can activate. See Deploy for the full breakdown.
Quick summary:
- Each activated site = 1 site slot
- Activations are permanent — no deactivation, no slot reassignment
- Exceeding your slot limit falls back to trial mode — you can keep working locally
CI environments
For non-interactive builds in CI, set SITEMD_TOKEN as an environment variable:
export SITEMD_TOKEN=sk_abc123...
sitemd deploy
Generate an API key with sitemd auth api-key. See CLI for the full list of environment variables.
Graceful fallback
If a build can't proceed (no auth, no slots, or API unreachable), it falls back to trial mode instead of failing. You'll see a message like:
No available site slots — building in trial mode (unactivated).
Purchase additional sites at https://sitemd.cc/add-ons
You can keep working locally. Buying more slots or authenticating unlocks activated output.
