Sitefinity Headless CMS Alternative

Learn the differences between Cosmic and Sitefinity Headless CMS


Sitefinity, from the Progress company, describes itself as a highly extensible, high-performing and easy to use Digital Experience Platform. They offer an all-in-one customer experience marketing solution, also offering headless CMS capabilities. However, as it tries to keep up with new pure Headless CMS solutions.

Monolithic vs Headless CMS

Sitefinity, as a monolithic CMS, and other older installed CMS systems like it, comes with a coupled front end application layer that requires additional development and maintenance. Cosmic is a Headless CMS meaning that the content API and presentation layer are decoupled which gives your team greater flexibility when it comes to where your content can go.

Cosmic provides everything your team of developers and content creators need: powerful and intuitive APIs for developers, and an easy-to-use dashboard for content creators. We've removed all complexity and CMS maintenance, so your team can focus on building great products faster, together.

But can't Sitefinity go Headless?

Although you CAN use Sitefinity as a Headless CMS or, as they put it, a decoupled CMS, you still have a lot of work to do to bring it up to the level of an optimized CMS system that's truly headless. And along with your application, you will need to maintain the CMS itself, adding more development costs and taking away focus from what really matters: creating great content and user experiences in your main website or app.
