The short version

  • Each has a real cost: GitHub acquired by Microsoft in 2018, reducing pure independence despite operational autonomy; MongoDB 16 MB maximum document size limits large single objects
  • They diverge on capability: GitHub covers Git repositories, MongoDB covers Document model.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GitHub

  • Acquired by Microsoft in 2018, reducing pure independence despite operational autonomy
  • Primary focus on source control differs from purpose-built project management tools like Jira
  • Pricing for enterprise features and private repositories adds up compared to some self-hosted alternatives

MongoDB

  • 16 MB maximum document size limits large single objects
  • No native JOIN support for relational data operations
  • Higher memory usage due to storing field names with each document
  • Eventual consistency in distributed deployments can cause data stale reads
