When does an Astro project need a CMS?
Not every Astro project needs one. Astro content collections and files can be a simple, effective choice when developers manage the content and updates naturally belong in the development workflow.
A CMS becomes more useful when content needs to be managed by a broader team, updated independently of code changes, reused across the site, translated, scheduled, or assembled into new pages. When nontechnical users are editors, the value of the CMS quickly increases.
ApostropheCMS adds that content-management layer without replacing Astro as the frontend.
You can keep the architecture and developer experience that made you choose Astro while giving the rest of your team the tools they need to manage the site.
