Editor on the left, a live preview of your actual Astro site on the right — updating within seconds as you write.
See exactly how your actual site looks, or ask a teammate or client for feedback before anything goes live.
Your real CSS, fonts, theme and custom MDX components render through the same code your visitors get. If it works in astro dev, it works here.
The preview runs on Astro's actual dev server with hot module replacement, so changes show up in seconds — not after a rebuild or a deploy.
The preview panel is resizable, with presets for mobile, tablet and desktop. Make sure your content holds up on every screen before it hits production.
Live updates are the heart of it, but the same preview is made for getting and giving feedback.
Send a private link to a stakeholder and they see the live site in their browser. No account or login needed.
Give a shared link a lifespan — an hour, a day, a week — so review links don't outlive the review they were made for.
Point Zero at a branch to see how changes look in context before they ever merge to main.
When code or content changes in your repository, the preview syncs automatically to reflect them.

Yes. ZeroCMS runs your actual astro dev server, which loads your real stylesheets, fonts, theme config, and custom MDX components. What you see in the preview is what gets published.
Typically, only a few seconds from keystroke to a visible change, through Astro's Vite-powered HMR. Very large sites (500+ pages) may see a slightly higher latency.
The first visit spins up a fresh cloud container running your dev server, which takes about 1-2 minutes.
Not today. The dev server runs in the cloud rather than on your machine, so live preview needs an internet connection. This is the trade-off that lets it work with zero local setup on any device.
The preview panel is resizable and includes device width presets (mobile, tablet, desktop) so you can check responsive behavior before publishing.
No. ZeroCMS reads your existing content collections and generates the UI. Your codebase has zero Zero-specific files before, during, or after using it.
Live collections refresh external data upon request. Great for dynamic data like inventory or scores, but they don't render MDX or image transformations, and they require an SSR adapter. For teams editing posts, docs, and pages, the ZeroCMS preview reflects your real rendered site.
Point Zero at your Astro repository and your team is editing in minutes. No setup, no rebuild, no code in your repo.
