Hi Matt,
How are you doing with this?
As you may already know: You can use any Python database API in a Server Module. For Mongo, you would use pymongo.
pymongo is not currently installed in the Server Module environment. We like to install whatever anybody needs, so if you do want to try using pymongo, just ask and we’ll install it.
Here is a list of the currently installed Server Modules.
For Postgres, we have psycopg2 installed. Again, just ask if you need something different.
In terms of hosting, AWS Relational Database Service provides a free tier, it may be worth checking if that’s sufficient for your needs (or perhaps a paid RDS instance is within your budget).
