Know what happened.
Then know what to fix.

Tracing

Model and tool calls in one timeline

BeamWeaver connects instrumented model calls, tool calls, and spans across an agent run. Jump from a failed step to its inputs, outputs, latency, and cost.

Monitoring

The operational signals that matter

Follow throughput, latency, errors, token usage, and cost as your agents run. Give your team a shared view of the work behind every outcome.

Alerts Coming soon

Get a signal before an agent failure spreads

Alerting is next. We are building it on top of the tracing and monitoring data your team already has—not as a separate black box.

One dependency. Trace context.

Instrument an agent
before lunch.

Add the dependency and configure one endpoint. BeamWeaver exports instrumented agent runs, model calls, and tool calls in the background.
