Comparison

ZeroCMS vs CloudCannon for Astro 2026.

Both keep your content in the repository. ZeroCMS leads on AI, codebase footprint and publishing. CloudCannon leads on API reach, governance and the repository.

ZeroCMS

Git-based · Cloud · From $15 / month, editors need no seat

Connect a GitHub repository and Zero reads your Astro Zod schemas and .astro components to generate the editor — no plugins, no config, nothing added to your repository. Editors work against a live preview of the real site, and every publish lands as a clean commit. An AI agent works in the editor, and eight content checks run on demand or as a pre-publish gate.

CloudCannon

Git-based · Cloud · From $49 / month

CloudCannon connects to a Git repository and lays a visual editor over the built site, so editors change the rendered page rather than a form. It hosts the build and the editing app itself and syncs every change back to the repository as a commit. Astro is one of the frameworks it builds, and its component and data editing is configured through files you add to the repo.

What actually differs.

AI capabilities

AI capabilities

ZeroCMS

A built-in agent you hand tasks to, with custom skills.

CloudCannon

No built-in AI.

Codebase fit

Code in your repository

ZeroCMS

Nothing. The editor is generated from the schemas and components already in the repository.

CloudCannon

A config file owned by the CMS, the content model declared a second time, a dependency and an integration in your Astro config.

Publishing and review

Selective publish

ZeroCMS

Publish one change while others wait.

CloudCannon

Everything pending publishes together.

APIs and extensibility

REST API

ZeroCMS

No HTTP API. The content is files in the repository, and that is the interface.

A full HTTP API, reads and writes, for any consumer.

Governance and access

Single sign-on (SSO)

ZeroCMS

No SAML SSO yet.

CloudCannon

SAML SSO is available.

Still not sure?

Zero adds nothing to the repository.

CloudCannon adds four things to your repository, the content model declared a second time among them. That matters if you want the repo left alone. Connect an Astro repo and see the difference in ten minutes.
