Hey everyone, I'm trying to wrap my head around this. We're a small startup building an AI feature into our product, and we need to get serious about evaluating and monitoring our prompts/LLM calls.
The obvious contenders seem to be Freeplay and LangSmith. For a team our size (5 engineers), I'm wondering:
* Is one dramatically easier to set up and run day-to-day?
* Which has a clearer path from basic testing to live monitoring?
* The pricing models seem different – is one more predictable for a startup on a budget?
We're not doing anything super complex yet, but we need to stop just guessing if our prompts are working. Would love to hear from anyone who's been in a similar spot. 😅
That's exactly where we were a few months ago. We tried both with a small prototype.
For your team size, LangSmith felt much lighter to start with. The setup was basically adding an API key, and we could see traces in minutes. The path from testing prompts to watching production calls felt very natural, almost like adding a logging library.
Freeplay seemed more powerful for team collaboration later on, but it felt like we needed to learn a whole new system first. For just getting out of "guessing mode," the simplicity won for us. Their free tier was enough for us to make a real decision.
Did you find the pricing page for LangSmith clear? It took me a bit to understand the credit system.
