FAQ

Questions you might have

What is MDFriday? How does it relate to Hugo?

MDFriday is Markdown site building infrastructure. We reimplemented Hugo's full build pipeline in TypeScript — runnable in the browser, compatible with 500+ Hugo themes, no Hugo CLI required.

Use the same engine via Obsidian plugins, the upcoming browser Studio, or export a ZIP to self-host.

What products are available now? What's coming?

Available now: Foundry engine, Obsidian Share plugin, Personal cloud hosting.

Coming soon: Blog / Wiki / Portfolio scene plugins, browser MDFriday Studio, AI theme pick and format conversion, i18n, Newsletter add-ons, and more.

How is MDFriday different from Obsidian Publish?

Obsidian Publish is the official hosted service — one click publishes your whole vault to the cloud.

MDFriday gives you full control: local builds; publish a note or folder; 500+ Hugo themes, export or one-click publish — with scene-specific plugins for Blog, Wiki, and more coming.

Does my note data get uploaded to your servers?

Your raw vault never uploads. Markdown and builds run locally (or in the browser); Guest publish only ships generated static HTML, CSS, and assets.

What's included in the Personal plan?

Personal includes a permanent hosted URL, custom slug, removal of the Built with MDFriday badge, and Studio site management after Google sign-in. See the pricing page for details.
