What is a Bucket?
A 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 support multiple languages?
Yes, we have localization that includes major languages and language locales (like en, en-US, en-GB, etc.) you can try out our Localization Add-on with any Free Bucket.
What is considered an API request?
An API request is any interaction with your Bucket via the Cosmic JS API. This can be a single page load to your Cosmic JS-powered website, an application request to edit an Object or any other request to get or edit content in your Bucket via the API. Accessing media directly does not count as an API request.
Do you have a free plan?
Contribute a resource to our community and you will be rewarded with a Free Bucket forever. This is different from other community programs that require logo attribution. What we want is to create a stronger community through technology education resources.
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 an external API 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 our Enterprise plan. You can read more on our Service Level Agreement page.
