Reviewer scorecard
“Best-in-class observability. APM, logs, and metrics in one place with excellent correlation. Worth every penny for production systems.”
“RadixAttention and constrained decoding are powerful features. Performance benchmarks are competitive with vLLM.”
“The pricing model is designed to surprise you. Custom metrics, log ingestion, and APM spans add up to terrifying bills.”
“Impressive research but smaller community than vLLM. The frontend language is interesting but adds complexity.”
“Datadog's land-and-expand across security, CI, and database monitoring makes them the observability platform to beat.”
“Constrained decoding and structured generation are the future of reliable LLM outputs. SGLang leads here.”
