Mattrbld is a Git-based headless content management system (CMS) designed for teams and individuals who want flexibility and control over their content. It allows users to manage website, app, or other project content without imposing specific presentation methods.

Mattrbld:

• Decentralized content management: Users control where content is stored, how it's delivered, and its presentation. It does not store content on external servers.

• Git-based: Content lives alongside code, providing version control. It interfaces directly with the user's repository.

• Flexibility: It's compatible with any frontend technologies. It's built for the Jamstack.

• User-centered design: Simplifies complex processes with modern technologies. It aims to provide a good user experience.

• Easy to use: The CMS is designed to be familiar to those who have used a CMS before.

• Live content preview: Users can preview their content.

• Offline capability: Mattrbld is a progressive web application that works offline, although publishing requires an internet connection.

• Content modeling: Allows users to create schemas for content.

• Unlimited projects and collaborators.

• Free for self-hosting: Mattrbld is an open-source project.

Mattrbld is not suitable for:

• Projects that require a drag-and-drop website builder.

• Media-heavy sites or content with significant binary data.

Mattrbld stores content in JSON and Markdown files with YAML frontmatter. It's designed to help manage the frontmatter of content. Mattrbld uses semantic versioning.

Mattrbld is designed for developers and agencies that create websites for small and medium sized clients. It gives them a way to update their sites without having to rely on the developer for content management, and does not limit them to a particular framework or frontend technology.
