SGLang provides fast LLM serving with RadixAttention for prefix caching, constrained decoding, and a flexible frontend language. Competitive performance with vLLM.
Reviewer scorecard
“Database branching is a killer feature — branch your DB for every PR, test with real data, merge back. Transformed how we handle database migrations.”
“RadixAttention and constrained decoding are powerful features. Performance benchmarks are competitive with vLLM.”
“Scale-to-zero means you actually pay nothing when idle. The cold start is noticeable (~500ms) but acceptable. For serverless apps, Neon is the obvious choice.”
“Impressive research but smaller community than vLLM. The frontend language is interesting but adds complexity.”
“Neon is making Postgres behave like a serverless primitive. The branching model will become standard — in 3 years, we'll wonder how we ever managed databases without it.”
“Constrained decoding and structured generation are the future of reliable LLM outputs. SGLang leads here.”
