Where each one falls short

Humanloop

  • No published pricing for standard plans; customers must contact sales for quotes
  • Billing based on logs created per API call, making costs unpredictable without usage estimates
  • Separate charges apply from AI providers (OpenAI, Anthropic, etc.) using customer's own API keys, adding external costs

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
