Our take
Pick DeepEval if you're on a python team who will run DeepEval locally at $0 and only open Confident AI Free / Starter $200 when they want a shared cloud. Pick TruLens if you're on a rAG team who will run TruLens locally at $0 (you bring compute and judge-model keys) — not Arize first unless they want hosted Signal at $50.
