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

Keycloak

  • Requires self-hosted deployment and operational expertise to install, configure and maintain
  • No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
  • Clustering and high-availability configurations require additional operational knowledge
  • Community support only; commercial support requires third-party vendors or distributions
