vLLM
- Tagline
- High-throughput LLM inference server with continuous batching and PagedAttention
- Description
- vLLM is an open-source, high-throughput inference engine for large language models. Its PagedAttention algorithm manages GPU memory efficiently, enabling 2–24× higher throughput than HuggingFace Transformers. It serves an OpenAI-compatible API, making it a drop-in replacement for production LLM serving.

Ollama
- Tagline
- Run LLMs locally — pull and run Llama, Mistral, Gemma, and 100+ models with one command and OpenAI-compatible API
- Description
- Ollama is the easiest way to run large language models locally on macOS, Linux, and Windows. With a simple CLI (`ollama pull llama3.1` → `ollama run llama3.1`), it manages model downloads, hardware configuration, and inference. Ollama's local REST API is compatible with the OpenAI API format, making it a drop-in replacement for cloud LLMs in development and privacy-sensitive production deployments. 163K+ GitHub stars; the most popular local LLM runtime.
