Per-tool support
Out of 105 analyzed products. Bars scale to the leader; numbers are absolute supportedCount.
Leader: OpenTelemetry with 43 supported products (41.0% of analyzed).
Observability coverage
Which products and frameworks integrate with which observability
stack? Per the May 2026 volumetric agent, observability / debugging is the single highest-demand
question in agent infrastructure (807 HN hits in the
last 12 months, 89% adoption in LangChain's State of Agent
Engineering 2025, six of seven published surveys treat it as a
top-three challenge). This matrix pivots the catalog's eight obs-* columns into a coverage view.
Coverage: 105/1002 products (10.5%) have at least one observability cell filled in. Of those analyzed, 62.9% declare support for at least one of the seven tracked tools. The rest of the catalog (mostly research papers and depth-floor rows) is surfaced as unknown by default — the matrix explicitly shows where research has bottomed out rather than papering over the gap.
Legend
- yes documented integration — citation in the cell tooltip
- no no integration / not applicable for this product class
- unknown not yet researched or research bottomed out at the depth-floor; treat as "we don't know"
