I've been using Payload CMS for more than a month now. It hard to appreciate the simplicity and performance without trying it. I encourage everyone to try it.
All you need is to create a model (Typescript class) to define how you want to structure your data, and you're done! It does support RESTFUL API outside the box, along with GraphQL. Very fast (we have a collection with 75,000 items) and response time is less than 100ms.
Keep up the great work
