It is super exciting to see projects like this! Is there anything similar that uses Postgres, or any other database that has a better reputation for data integrity than Mongo? I'm confused to see this marketed as serverless- it seems very much server-full. Is there an easy-to-follow guide for setting up cloudboost on Azure or AWS?
