A basic personal project to try MongoDB.
It uses the Stack Exchange API as a data source.
The web app allows me to store a curated set of questions locally, pulled from various Stack Exchange sites using their public API. Volumes are small and read-only, so there is no need to register or authenticate my application. I just use their anonymous usage, with its (300 calls per day per site).
For the MongoDB, I use the community download version 6.0.6, which includes Compass:

My MongoDB collections (questions and test_questions) use one additional compound index on question_id and site. I use the mongosh command line utility to automate creation of the index.
Downloadable from here (I use v 1.10.1):

I also use the separate command line tools for collection import/export utilities:

Specificially, this is version 100.7.3.
