Penmark CMS

appsinprogress.com·Developer Tools

Penmark CMS is an embeddable content management system for Markdown-based sites that store content in GitHub repositories. It addresses the need for direct editing of static site content without leaving the site or using separate tools.

The system supports login through a GitHub application that grants access to repository contents. Users can create and modify drafts, which are committed to a drafts folder. Publishing moves content to a posts folder and triggers a site rebuild. An editing interface offers a choice between WYSIWYG and Markdown modes. All changes remain synchronized with the GitHub repository, and the editor can be used from any device.

Penmark integrates directly into a website. Installation involves adding a script that loads the LoginClient.js module from the official domain and initializing it within a React component or similar setup. It is compatible with static site generators that process Markdown, including those used for Hugo, Jekyll, and Next.js sites. The editor appears embedded within the host site rather than on an external dashboard.

The project is released under the MIT license. No pricing information appears in the documentation.
