SGLang trends on GitHub's Python list
SGLang is an open-source inference framework hosted by LMSYS for large language, vision-language and diffusion models, optimized for agentic workloads, large-scale serving and RL rollouts; the repository also includes SGLang Diffusion, its built-in image and video generation engine. It supports a wide range of GPUs, TPUs, NPUs, CPUs and Apple Silicon, including NVIDIA B200/B300 and H100, AMD Instinct, Google TPU, Huawei Ascend, and ships via Docker images or a uv install. The project offers a Cookbook, docs and learning resources such as Mini-SGLang, and long-term contributors can apply for coding-agent sponsorship covering Cursor, Claude Code or OpenAI Codex.
For teams serving models themselves, SGLang is one of the main open-source alternatives to vLLM, with notably broad hardware coverage.
