Foglamp

Trace AI-agent calls and track costs, latency, and response quality.

Meet Foglamp

Foglamp gives developers visibility into applications built with the Vercel AI SDK. Its instrumentation records model calls and tool activity so teams can follow the prompts, responses, timing, and token use behind an agent's work. Traces and sessions make it easier to examine a particular interaction when something goes wrong.

The dashboard groups spending by model, agent, and customer, helping teams understand where usage is accumulating. Evaluation tools assess responses, and alerts flag changes in cost or quality. Developers can connect an application, inspect its first traces, and use the same record to investigate behavior as the workload grows.
