deco CMS vs Mattrbld

deco CMS is an open-source, self-hostable content management system for commerce teams and enterprise operations managing storefronts across platforms and sites. It pairs a visual editor for business teams with an AI agent for other changes, operating on the customer's stack. Non-technical staff can edit, create, and publish without tickets, while design-system components and tokens can remain locked. It works with Shopify, VTEX, Wake, VNDA, and headless or custom stacks. Teams can make audience variants by country, state, or UTM and run A/B tests at the edge; results can be exported to Google Analytics 4. Changes are organized as changesets with shareable previews, while content and code stay in the repository, and the page describes rollback as one click. The agent follows system prompts, design-system references, and repository skills; TypeScript typing can block invalid data-layer commits. The open-source core is free. Studio costs $20 a month, billed at $20 /user/month, while Enterprise costs $10,000 a month. The Outcome operation plan has no listed price.

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.
