Masthead is an open-source publishing engine where themes define both the website and the editing experience. Write in Markdown or HTML, publish to your own domain, and focus on content instead of your CMS.
The best editing experience isn't one with unlimited options. It's one designed specifically for the website you're publishing.
Read →Every theme defines its own editing experience. Site owners only see the settings relevant to the website they're managing.
Connect your own domain in minutes. Masthead verifies ownership, provisions TLS automatically, and serves every site securely over HTTPS.
Write pages and posts in Markdown or HTML. Themes decide how content is presented, allowing the same content to power many different websites.

Install themes from the marketplace or upload your own. Every theme includes templates, styling, and a generated editor tailored to that website.
