Show HN: Ragas – Open-source library for evaluating RAG pipelines | Hacker News

congrats on launching! i think my continuing struggle with looking at Ragas as a company/library rather than a very successful mental model is that the core of it is like 8 metrics ( https://github.com/explodinggradients/ragas/tree/main/src/ra... ) that are each 1-200 LOC. i can inline that easily in my app and retain full control, or model that in langchain or haystack or whatever. why is Ragas a library and a company, rather than an overall "standard" or philosophy (eg like Heroku's 12 Factor Apps) that could maybe be more universally adopted without using the library? (just giving an opp to pitch some underappreciated benefits of using this library)
