SGLang vs vLLM: Which LLM Serving Framework Should You Use?

Runc.ai/sglang-vs-vllm/. Key Takeaways vLLM is still the default starting point for many teams because it is widely adopted, easy to get running, and strongly associated with high-throughput LLM serving. SGLang is increasingly compelling when you care about aggressive serving optimizations, structured outputs, multimodal, and lower-level serving control. Both frameworks expose OpenAI-compatible APIs, so the practical decision often comes down to feature fit, operational preference, and model rather than API style alone.
