As answered by people managing Simple Data API and Fern.
Simple Data API's answer
specifically build for non technical users to control the frequency of their data and updates. Helps developers focus on the project, not the data.
Simple Data API's answer
Easy to get started in minutes. Inexpensive and easy tool for the freelance toolkit. Client friendly, easy to edit, easy to share.
Simple Data API's answer
The primary user is either A.) a non-technical person who needs to ship structured data to their webapp, page, or online tool. Or, B.) a web developer who doesn't need to develop a full CMS solution for a small amount of custom, frequently changing client data.
Simple Data API's answer
As a webdev, I've built a lot of websites that were bloated with databases and content management just to update a few lines of text a few times a week. This solution give developers and easy to access dynamic endpoint, and keeps the client in control of their structured data in an easy to update form.
