Most AI teams say they “evaluate prompts,” but what they really mean is: someone eyeballs a few outputs, drops screenshots in Slack, and hopes nothing breaks.
PromptLayer is built for the more honest version of that workflow.
You get request tracing, prompt versioning, evals, and Tables for reviewing outputs like a real QA/eval workspace. That makes it much easier to catch regressions, compare changes, and understand why an AI feature got better or worse.
The thing I like is that it doesn’t pretend evals are just a magic score. It gives you the actual workflow around reviewing failures and making shipping decisions.
If you’re putting LLM features in production, this is the kind of tooling you eventually need.
