Honeycomb
capability high-cardinality + reliability.
Pricing (directional): Event-based observability pricing; excellent high-cardinality querying; not LLM-specialized.
Lock-in risk: higher = more lock-in (worse). Overall already inverts this dimension.
When your agent outage is an infra mystery, Honeycomb shines. Still pair with an LLM-native tracer for prompts.
