You'll build your site locally, then [deploy & host wherever you want](https://sitemd.cc/docs/deploy#deploy-targets+newtab). **Can I use sitemd for client sites?**\n Absolutely. 15% bulk discount when purchasing 50+ site slots at one time. **Is there a free version/trial?**\n Yes. sitemd can run in [free trial mode](https://sitemd.cc/docs/build-modes#trial-mode+newtab) forever. You can preview [all features](https://sitemd.cc/docs/build-modes#all-features-work-in-both-modes+newtab) in trial mode. You only need to pay when it's time to deploy your site. **How many sites do I get?**\n When you initially upgrade/purchase sitemd for $79, you get 3 starter site slots. If you need more sites, you can purchase additional slots for $19/ea or 50+ at one time for a 15% bulk discount. **What counts as 1 "site"?**\n Any set of pages (could be 1, could be 100+) that share the same site title, brand name, and deploy URL. We call this your "site identity" and it's how we verify your site's activation status.\n Note: subdomains are considered their own unique deploy URL, so if you need to deploy pages to both mydomain.com and sub.mydomain.com, that uses 2 site slots. **Can I reassign my site slots?**\n Activating a site is permanent — it cannot be undone, refunded, or credited. **Do you offer refunds?**\n No. You can fully preview all sitemd functionality for free for as long as you need before making a purchase decision. **Are future updates included?**\n Yes. All sitemd [updates ship to you automatically](https://sitemd.cc/docs/updates+newtab). --- ### Still have questions? Email us at support@sitemd.cc
