Reviewer scorecard
“The API is clean, the React Email integration is brilliant, and deliverability is excellent. Replaced SendGrid in 20 minutes and never looked back.”
“RadixAttention and constrained decoding are powerful features. Performance benchmarks are competitive with vLLM.”
“Young company with a smaller scale than SendGrid or Postmark. But the developer experience is so much better that it's worth the risk for startups. Monitor deliverability closely.”
“Impressive research but smaller community than vLLM. The frontend language is interesting but adds complexity.”
“Building beautiful transactional emails used to be painful. React Email components make it feel like building a web page. Game changer for my client projects.”
“Constrained decoding and structured generation are the future of reliable LLM outputs. SGLang leads here.”
