You can add UpTrain to the list. We are building an open-source LLM evaluation tool with pre-built evaluations such as factual accuracy, retrieval quality, response completeness, tonality, etc. as well as easily extendable framework which allows LLM developers to define their custom evaluations by chaining individual operators.
