Because Gatsby pre-renders webpages only when they change, there is much less content management activity that needs to happen at the backend. Gatsby decouples the frontend from the backend. As a result, it treats your CMS as if it were headless, even if it’s not.
If you don’t already have a headless CMS, then Gatsby offers a good reason to acquire one. A headless CMS offers a single manageable source for content with the possibility for multiple outputs. A single content element can be reused across web, apps and other platforms, making omnichannel marketing a cost-effective reality. Content elements can also be easily combined with each other to support multi-variant campaign testing.
Using a headless CMS with Gatsby gives your website scalability, resilience and adaptability. It also promotes an agile way of working which can result in content projects being finished quite rapidly.
