NoCodeBackend provides a minimalist interface to create database and use it using API. The SQL editor is a good feature to "load" sample data for testing. The pros are the ease of starting with it. The option of foreign key is helpful.
There are areas for improvement such as getting limited number of items from the DB using API. The documentation can be improved as well. As a new(er) startup, many SaaS companies focus mostly on product building and marketing, but what they de-prioritize is the documentation, which actually should also be given considerate weightage as customers need the documentation to go beyond getting started!

I am giving 5 tacos assuming that the developers will keep working on this product. A good way to identify is to see the roadmap and new feature launches, improved documentation, new tutorial videos etc.
