Streamlit seems very much alive. I used it on and off in the past. Went to their website and it looks very much alive.

Ditto for Weights and Biases.

They are in the "Year unknown (12)" category but that's a weird thing to include.

Plus they aren't even AI products, but either have vigorous pre-AI use (W&B) or are completely non-AI but just used by lots of prototypes (streamlit)

Yes, it's active and even had a new release last week

it's because this is just unverified slop that i doubt was thrown together by a human. Langfuse has ongoing conferences and is still used by many frameworks.
