KoboldCpp pros and cons

Single self-contained executable with no install and no dependencies on Windows, macOS, and Linux
Runs any GGUF model on CPU or GPU (CUDA or Vulkan), with partial offload and broad backward compatibility
Bundled KoboldAI Lite UI with chat, instruct, adventure, and storywriter modes, character cards, memory, and world info
Lots of extras in one tool: image generation, Whisper speech-to-text, TTS, vision, MCP tool calling, and RAG
AGPL-3.0 licensing on KoboldCpp and the Lite UI has obligations for anyone building a networked service on it
You must source and download GGUF model files yourself; none are bundled
Getting good GPU speed still requires picking the right build and tuning offload layers and context size

vLLM pros and cons

Industry-leading throughput via PagedAttention
OpenAI-compatible API for easy integration
Broad model and quantization support
You must provide and manage GPUs and infrastructure
No official managed cloud from the project
Rapid release cadence can introduce breaking changes
