Common questions about ApostropheCMS

ApostropheCMS is an open-source headless CMS for JavaScript teams that combines a code-first architecture with in-context visual editing. It's built for development teams that need a flexible backend framework and a content editing experience their editors will actually use without having to choose between the two.

Yes, ApostropheCMS is open source under the MIT license: no usage limits, no vendor lock-in, no surprise bills. You own your code and your data. For teams that want to go further, Apostrophe Pro includes advanced tools for permissions, SEO, AI translation and more.

And if you're delivering websites to your own customers — each with their own isolated site — Apostrophe Assembly scales the whole thing into a multitenant platform built for exactly that. Assembly

But the foundation is free and open source, and it always will be.

You'll run one command, follow the prompts, and you'll have a working local project in a few minutes. Our Astro starter kit is the fastest path to a production-ready site with visual editing built in.

ApostropheCMS is the only open source CMS that combines true in-context visual editing with Astro. Apostrophe and Astro connect through the official @apostrophecms/apostrophe-astro integration package. Apostrophe handles content management, URL routing, and content delivery. Astro handles page rendering using whatever frontend components you prefer. The result is true in-context, click-to-edit on the live site.

Editor happiness is a core product principle, and we think happiness often comes down to empowerment and expectations. ApostropheCMS's editing interface is visual and in-context: your editors work on the live page, not a separate dashboard. And we regularly release additional tools that give editors the power to create on their own. Our thought is the more they can do, the more time developers have to focus on extending the CMS as needed.

Yes. ApostropheCMS can be self-hosted on your own infrastructure, deployed to any Node.js-compatible hosting provider, or run on our managed cloud. You own your data and your deployment, no platform dependency required.

ApostropheCMS is built for JavaScript developers and teams who need a CMS that works for both developers and content editors. It's particularly well suited for teams building with Astro (optional), managing content across multiple sites or locales, building custom digital experiences where off-the-shelf CMS behavior just isn't enough, or delivering websites to their own customers at scale.
