Where each one falls short

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

Honeycomb

  • Free tier caps at 20 million events per month and 100 million metrics data points
  • Pro tier starts at $150 per month for only 50 million events, with cost scaling per additional event block up to its 750 million event ceiling
  • Enterprise tier's event and data point volumes are variable and its price is custom, requiring direct sales contact
  • Telemetry Pipeline is billed separately at $0.10 per GB on top of the base plan price

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
