⚔ Langfuse appears in the Perception Lab: forced-choice runs vs Braintrust →

When buyers ask ChatGPT, Claude, and Gemini about llm & agent evals, Langfuse ranks #4 of 15, a Visibility Score of 35 in LLM & Agent Evals .

These rankings are measured from what the three models know from training, not a live web search. The live-web grounded surface is rolling out across the index. Methodology.

How AI sees Langfuse

Fourth in a 15-horse eval race, nowhere else.

Where it wins. Langfuse gets named in 43% of LLM and agent eval queries, a real foothold in a crowded 15-tool field. The 'Enterprise pick' prompt theme is doing work, signaling that at least one buyer segment hears a credible story.

Where it loses. A first-pick rate of under 10% means the three tools ranked above it are absorbing most of the purchase intent. The complete absence from startup and small-team themes cuts off a natural adoption funnel that rivals like LangSmith are almost certainly capturing.
