What is a Bucket?
A Cosmic JS Bucket is the main piece in the Cosmic JS content structure. It's very flexible and can power the content for your entire website, a portion of your website, or a micro-app on your website that requires dynamic, easy-to-manage content.
Do you have a free plan?
Yes, you can get started with our Free plan and upgrade as needed. You can have one Free Bucket at any given time for testing and development. After you upgrade your Free Bucket, you can add a new Free bucket.
Can I just use the Cosmic JS API and host my app separate?
Yes you can use Cosmic JS to store and access content via the Cosmic JS API and host your app elsewhere. We make it easy to deploy your web app to the Cosmic JS App Server, but this is not required to use the API.
Can I add Cosmic JS-powered content to an exisiting website or app?
Absolutely! Cosmic JS makes it easy to add dynamic content to any website or internet-connected application. This applies to exiting and new projects built in any programming language. If you can access the endpoint you can add Cosmic JS-powered content.
What happens if I exceed my plan's API usage limit?
We'll get in touch before this happens and, with your consent, move you to a higher plan.
Do you have guaranteed uptime?
Yes! We guarantee uptime of 99.95% on all our paid plans. You can read more on our Service Level Agreement page.
