Products
Selected offerings — the AI products recorded here, not the vendor's full catalogue.
-
Open-source observability platform for AI agents: captures traces of LLM and tool calls, analyzes every run for failures with its flow-1 model, and adds evaluations, an agent debugger, labeling queues, dashboards and SQL access, on Laminar Cloud or self-hosted.
Inside Laminar
-
Laminar Signals uses a trace analysis agent to identify AI agent failures and produce structured events for monitoring and alerts.
-
Laminar Agent answers questions about project data by querying it directly.
