Decap CMS vs Mattrbld

Decap CMS is an open-source content management system for Git-backed static sites. Its web editor gives non-technical contributors structured fields, rich text, and live preview, while draft, review, and publish statuses support editorial workflows. Content remains in the user's repository, preserving version history and enabling branch workflows and deployment checks. It connects to GitHub, GitLab, Gitea, Bitbucket, Azure, Git Gateway, proxy, and test backends. Editors can work with a media library and integrations such as Cloudinary or Uploadcare. Content models can include collections, nested structures, relation fields, and slug behavior; developers can add widgets, editor components, and plugins. The MIT-licensed CMS is free and self-hosted, so users supply authentication and a backend. The Free plan is free and lists one site and one seat. Pro is €19 a month, then €10/site and €6/seat per month for additions. Deploy notifications are currently available for GitHub-hosted sites; GitLab support is on the roadmap.

Mattrbld is a Git-based headless CMS for creating and managing content without tying editors to a particular frontend framework. Content remains in Git repositories rather than on Mattrbld’s external servers. After importing a project, users can edit offline, but must reconnect to publish changes. Schemas define content fields and validation rules, which Mattrbld uses to create editing forms. It supports JSON and Markdown files with YAML frontmatter; plain YAML support is planned but not implemented. Developers can implement a preview route using Mattrbld’s protocol to show content updates in real time. Repository communication uses Git; its documentation names GitLab, GitHub, and Bitbucket as providers that require a CORS proxy. Mattrbld does not require its own account, but collaborators need Git-provider accounts to access private repositories or sync. It is free, with an official hosted instance and a self-hosted core. The hosted instance has no availability guarantee, and its provided CORS proxy is intended for small-scale private projects. Mattrbld can also be built from source and hosted as a single-page application.
