What do you like best about this product?

When I was still not using this I just rely on vibe check but now it has the ability to run to check if the new prompt somethin on the old prompt. It is also more faster than other platform so it is convenient to use.

What do you dislike about this product?

When the humanloop api went down, the ai features would break because it has dependent uptime. Sometimes I am worried about the accuracy of the platform given.

What could make it even better?

For us to get answer instantly and the data is still saved for review. Also to build native caching, The Platform is working smoothly and very useful.

Final thoughts, wrap up what you think

I would recommend this to my colleagues because it has reliable ai features and support code first approaches.

What was your first impression when you started using it?

Nice to have stuffs like prompt revisioning,evals and observations in one place. Helped me being less scattered in when it comes to those things.

What feels confusing or hard to use?

Making advanced evals beyong simple use cases can be a fair bit time consuming. Although once its running its great, but getting there isnt quick at all.

What’s still missing for your needs?

Would be nice to have the prompt management connected to actual prod in a seamless way. It requires a bit of wiring and might feel a bit slightly out of sync because the handoff between the two isnt smooth, atleast in my use case.

Final thoughts, wrap up what you think

For any teams that ships LLM features, its a tool to look into. Core product is solid as it gets.

What feature do you use most often?

On a few personal projects, I tried Humanloop for prompt testing and LLM evals; its playground and observability tools helped make iterating on prompts quite seamless and enabled shipping more consistent outputs fast. Sadly, I had to turn to substitutes like LangSmith after joining Anthropic.

What do you dislike about this product?

Most often used in Humanloop was the prompt playground with integrated evaluation, letting me rapidly test variants, run automated evaluations, and see performance measures right there while iterating for client projects. I regret that flawless workflow since the platform is now joining Anthropic.

What new feature would you love to see added?

A multi-turn agent with end to end evaluation integrated into the Humanloop playground would be fantastic. Apart from saving a lot of time on client AI tools, it would allow me to interactively test complex chains and workflows while automatically scoring the whole conversation flow against tailored benchmarks.

Final thoughts, wrap up what you think

For quick LLM iterations on client work, Humanloo's outstanding prompt playground and evals when active would be highly recommended. Now that the Anthropic movement is behind us and sunset is approaching, I would suggest instead solid alternatives like LangSmith or Weights & Biases.
