Track, version, and optimize prompts across your LLM stack.

PromptLayer is a fantastic logger and registry. But we found ourselves needing more automated evaluation features (like 'score this output against a golden answer'). Tools like LangSmith or Arize offer deeper evaluation flows. PromptLayer is simpler and easier to start with, but might be less feature-rich for deep QA.

The ability to version-control prompts is the killer feature. We treat prompts like code now. We can roll back to v3 if v4 starts performing poorly. Integration was literally one line of code change. It's a bit pricey for high-volume logging, but for the dev cycle, it's worth it.

PromptLayer acts as a log of every request we send to OpenAI. Being able to search through history to see *exactly* what prompt caused a weird response is invaluable. The visual prompt registry allows our non-technical PMs to tweak system prompts without touching the codebase. It bridges the gap between engineering and product.
