Industry-Leading Professionals Choose Cosmic

When you build applications with Cosmic, you're in good company. Everyone from Developers to Directors of Marketing to Fortune 500 CTO's has had great things to say about Cosmic.

"It was literally 10 to 15 minutes from taking the SDK, to getting the data I needed, to consuming it. We cut our server response time down from 300-400 ms to about 50 ms. Instead of needing to query the Shopify API, now we only need to query Cosmic."
John Leider, Vuetify
"Really like Cosmic. Build your content in a CMS and get a REST or GraphQL API immediately! Slick tool to make dev quicker! Even has Gatsby Preview so you can check out changes before publishing."
Chris Sevilleja,
"The headless CMS we chose had to tick a lot of boxes. At the end of the day, though, it needed to be easy for our external writers to use. We recorded a quick screencast video internally showing how to set up a piece of content, sent that out to our team, and I haven’t had a question from any of our writers since."
Katie Prowd, Co-Founder of Hypometer Technologies
"Cosmic allowed us to easily integrate a secure and fast back-end API into our React app. Cosmic fit our needs with its simple web-based dashboard so that members of our marketing team can create, edit, and delete new content on the fly. Our team has been enjoying the ease of use with the new system."
Owen Liversidge, Lead Developer, Tripwire Interactive
"Leveraging the Cosmic GraphQL API allows for easy updates to our news and blog, while keeping payloads small and fast. Integration with Cosmic could not be easier thanks to their great support. We look forward to developing more features on the platform."
Dustin Brink, Derive Systems

Who We Are

Cosmic is a global team of developers, designers, and marketing experts devoted to solving content management problems from first principles. We found many of the most popular tools for managing digital content inadequate for the evolving API economy, so we set out to create something better.

Frequently Asked Questions

A headless content management system (headless CMS) is a kind of CMS that creates more inherent separation between the back-end and the front-end of your applications. This allows for lots of useful functionality - for example, plugging an application into new front-ends (think: websites, mobile phones, smart devices) becomes much easier - because your code doesn't have any dependencies on the front-end.

This is one, simple, example of what makes headless CMS so great. In our eyes, it's going to become a primary means of content management in the coming decade. Learn more about headless content management here.

Hard to say. Headless CMS is not for every team, but if you're looking to reduce development time spent on CMS infrastructure, you're definitely in the right place. If you want a content management system that integrates better with the accelerating API-based economy, headless will be great for you. If you want to enable better collaboration between the infamously siloed development and marketing teams, headless is your best bet. Learn more about how to decide if headless is the best choice for your business.

Jamstack refers to a new architecture of web and application development. In a nutshell, this architecture allows for a more modern approach to creating applications. It sets your application up for success as we move into a digital age that requires more flexible applications.

There are 2 ideas that make up the new Jamstack architecture - pre-rendering, and de-coupling. That de-coupling concept is where headless CMS comes in - a headless CMS de-couples the back-end of your application from the front-end.
