But they're solving pretty different problems, and choosing the wrong one for your stack has real consequences. I went deep on both so you don't have to. In this review, I explored: ✅ Ragas pioneered reference-free RAG evaluation — no hand-labeled ground truths required — with solid, research-backed core metrics like faithfulness, context precision, and answer relevancy ⚠️ Ragas has a known production issue: when its internal LLM returns invalid JSON, you get NaN scores with zero explanation — a genuinely painful debugging experience, especially outside LangChain or LlamaIndex ecosystems 💰 DeepEval's Confident AI cloud layer offers a free tier covering 10,000 traces monthly, with paid plans starting around $20 per user — and 50+ metrics covering RAG, agents, red teaming, and safety 🔍 Every DeepEval metric ships with LLM reasoning alongside the score — so when an eval fails, you know exactly why, not just that it failed 💬 DeepEval was built by ex-Google and Princeton engineers as essentially pytest for LLMs — evals run directly in your CI/CD pipeline like regular unit tests 🧠 DeepEval actually ships Ragas metrics inside its own framework — this isn't really an either/or choice, and teams that outgrow Ragas don't have to leave those metrics behind There's a specific moment in your build where the right framework stops being Ragas — and most teams only figure that out after hitting a wall.
