Publish all content straight back to the GitHub repository. Done.

Built on a foundation you can trust.

No vendor lock-in.
All content lives co-located with your code in your own GitHub repo. You own your content. You own your code.
Zero risk to try.
If you ever stop using Zero, your site works exactly as it did before, because Zero never changed your code.
No training needed.
Working with Zero feels like working with your local files and folders. The visual editors ensure non-technical people feel right at home.

Testimonials

From our customers

From all of the CMS we've tried for Astro Starlight so far, ZeroCMS is the best CMS we've found. The live preview and history of changes are amazing. Nothing needed to be set up in your project.

Early partners

We're looking for a few teams that regularly publish content (docs, blogs, changelogs, or similar). In exchange for feedback, e.g., via Slack or short weekly calls, you'll get free access until the public launch, meaningful input on our roadmap, and a direct line to the founder. In return, we ask that you be open to serving as a reference if Zero works well for you.

Frequently asked questions

Every other CMS requires you to maintain a configuration file where you need to redeclare your content structure, schemas, and components. And keep them in sync forever. They also lack a proper component and MDX support, and come without a true live preview.

Zero does all that automatically. All you need to do is connect your GitHub repository to let your non-technical team start creating content with full support for the existing schemas and components in your project.

Yes, Zero should work with any Astro (v4-v6) site that uses content collections. We have tested Zero with some of the largest sites, including astro.build, the official Astro docs, Starlight, and the Cloudflare docs. If it works for them, it likely works for you!

No, they don't. Additional team members can be invited by email straight from the dashboard.

Yes, Zero fully supports monorepos. We only checkout your actual Astro directory from within the repo to avoid cloning unrelated files. If you're concerned about security, you can also move the Astro site to its own repository and give the GitHub app access to that one only.

Not yet. Zero currently supports GitHub only.

Yes, you can share a link to the live preview with your team and clients. The preview is available to anyone with the link, without the need to log in.

You'd have to convert your site to use content collections first. It's straightforward and works well for all kinds of sites, including landing pages, blogs, and docs.

Every week you wait is another week maintaining a CMS that should just work.

With Zero, you'll unblock yourself and your team in less than 5 minutes. Get early access now and experience the new AI-native Astro CMS yourself.
