Evaluation gap (the next frontier after observability)

LangChain's State of Agent Engineering 2025 found that 89% of practitioners have observability adopted but only 52% have evals — a 37-point structural gap. The Berkeley RDI MAP study (Q1 2026) corroborates: 74% rely primarily on human evaluation. The Datadog State of AI Agents 2026 report lists "reliable evaluation loops" as a top recommendation. This view answers the catalog-level question "how do I know if my agent is actually getting better?" — the question that had no catalog-level surface before T1-2.

This view's distinctive value is the gap. Every comparable catalog tracks eval tooling on its own. We're the first to surface "products that have observability but no eval" row-by-row — the structural failure mode the LangChain survey identified.

Out of scope: eval methodology comparison (LLM-as-judge vs human rubric vs canary set) and benchmark scores (T1-4 territory). This view tracks integration support only — which products plug into which eval tooling.

Observability adoption

88.0%

of 100 analyzed catalog products ship at least one observability integration. Industry headline: 89% (LangChain 2025).

Eval adoption

44.0%

of 100 analyzed catalog products ship at least one eval integration. Industry headline: 52% (LangChain 2025).

Eval orphans

43

products with observability ≥1 tool but zero eval tools. These are the structural failures the LangChain survey identified. Use the "only eval-orphans" filter below to see them.
