About Vellum
Vellum is an LLM application development and operations (LLMOps) platform that centralizes the full AI product lifecycle—prompt engineering with side-by-side model comparisons, visual workflow orchestration, dataset-based evaluations with custom metrics, and production monitoring with per-trace observability. It is backed by Y Combinator and is available on the AWS Marketplace, targeting teams shipping RAG pipelines, support chat, and structured extraction to production. Alternatives: Braintrust (scalable LLM evaluation and continuous improvement for production systems), Langfuse (open-source LLM observability and prompt management, self-hostable), LangSmith (prompt versioning and playground tightly integrated with LangChain/LangGraph), Humanloop (evaluation-driven prompt development with human feedback loops).
