SGLang provides fast LLM serving with RadixAttention for prefix caching, constrained decoding, and a flexible frontend language. Competitive performance with vLLM.
Reviewer scorecard
“The free tier is absurdly generous and the cold starts are essentially zero. For APIs, middleware, and edge logic, nothing else gives you this performance at this price.”
“RadixAttention and constrained decoding are powerful features. Performance benchmarks are competitive with vLLM.”
“The Worker runtime has limitations — no Node.js stdlib, size limits, CPU time limits. Know the constraints. But for what it does well, it's unbeatable.”
“Impressive research but smaller community than vLLM. The frontend language is interesting but adds complexity.”
“Cloudflare is building the programmable internet. Workers + D1 + R2 + AI = a complete platform that runs at the edge. They're quietly becoming the default infrastructure layer.”
“Constrained decoding and structured generation are the future of reliable LLM outputs. SGLang leads here.”
