OpenTelemetry in, nothing to run

Point any OpenTelemetry SDK at Hexel Studio with your token. Metrics, logs and traces arrive over OTLP; there is no collector to deploy.

Isolated by identity

Your organization comes from your token, never from a header someone can set. Every query is scoped to it before it runs.
org: acmetenant from the token, not a header

Logs you can search

Filter by service, level and text, over the last hour or the last month, and open any line to see its labels and fields.

An audit log you can check

Platform actions are signed when they’re written. Open any event and verify it, from the console or the API, to prove it hasn’t changed.

Kept, write-once

Audit events are archived to write-once storage and can be replayed. Titan’s decision ledger exports here too, so one place holds the whole story.
