Promptfoo
Editorial take
Promptfoo is the eval gate that looks like unit tests, which is why it belongs in a factory. It will not review your PR style. Use it on hold-out cases the agent cannot edit. MIT core; cloud is optional.
DeepEval
Editorial take
DeepEval vs Promptfoo is taste: pytest vs YAML. Both are gates if you treat them as gates. LLM-as-judge metrics need a second look; they are not typecheck. We list both because teams actually pick one.
