SIGNAL LEDGER
Start tracing
Live agent telemetry

Operational signal for everything your agents do

Capture structured traces, tool activity, and memory changes. Follow every decision path the moment it unfolds.

01 / Observability

Every span, tool call, and memory write — in one ledger.

Replace four dashboards with one. Traces, evals, costs, and policy violations stream into the same ledger — addressable, filterable, and exportable.

  • OpenTelemetry-compatible, drop-in for existing agents
  • Cursor over decisions to scrub through reasoning
  • Diff a run against any prior trace, side-by-side

One signal. Three resolutions.

Zoom from a single event up to the full run, then onward to the ledger of every decision your fleet has ever made. The shape of the data never changes — only the lens.

03 / What runs on the ledger

Four pillars, one stream.

The ledger isn't four tools stitched together. It's a single structured stream you can address from four lenses.

ITraces

Structured by default

OpenTelemetry-shaped spans. No schema gymnastics, no probe scripts — drop the SDK in and the ledger fills.

IIEvals

Tied to the trace

Every run carries the eval verdict it earned. Filter the ledger by failure mode and replay the exact context.

IIICosts

Per decision, per agent

Token spend rolled up the span tree. See which step, which tool, which model is bleeding the budget — in real time.

IVPolicy

Auditable signal

Memory writes, tool authorizations, and PII edits are logged with provenance. Built to satisfy SOC 2 / HIPAA review.

04 / Ready when you are

Trace one run. Keep the ledger forever.

Free during alpha. Bring your existing OpenTelemetry pipeline or pull our SDK — the first trace lands within 90 seconds.
