Mattrbld review
A free, developer-friendly CMS for Git workflows and media-heavy web projects.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Mattrbld is an open-source, headless CMS that stores content alongside code in Git repositories. It is designed for developers, agencies and content editors working on websites, apps and other small to medium-sized projects. Its core model combines schema-based content modeling, collections, rich-text editing with HTML or Markdown output, drafts, publishing permissions and granular permissions for collections and media. As a progressive web application, it can also support offline editing while keeping the working environment centered on the web.
For cost-conscious teams, Mattrbld is free for self-hosting, and an official hosted instance is available. The product covers a broad content workflow without requiring a separate commercial tier for its listed capabilities: users can create drafts, manage publishing permissions, preview content in real time and organize assets in a Media Library. The media layer is a notable strength, covering images, videos, PDFs and archives with advanced metadata management. This makes Mattrbld a particularly good fit for projects where structured content and asset control matter as much as text editing.
Its ecosystem fit is centered on Git, with support for GitHub, GitLab and Bitbucket and a deployment method based on Git commits. That approach suits teams already managing content and code through repositories, while schema modeling and approval-oriented permissions give editors a defined publishing process. The trade-off is focus: platform coverage is limited to the web, and the Git-centered workflow may be less suitable for teams seeking a broadly distributed, non-technical content platform. Choose Mattrbld for free, media-rich web projects that value open source and repository-based workflows; consider an alternative if mobile or desktop coverage, or AI features, is a priority.
