The same numbers your daemon prints,
laid out for a quarterly review.

Every chart below is built from real log data. Spend by project, daily rhythm, provider mix, reconciliation deltas. The same values the CLI prints, structured so finance can read them without a terminal.

Instrument 01

Spend by project.

Every request is tagged with a project slug at capture time. The daemon infers attribution automatically from the working directory. No manual labelling required.

Instrument 02

Daily cost rhythm.

Spend doesn't arrive uniformly. Spikes signal batch runs, test cycles, or new agents being evaluated. The daily chart surfaces those rhythms so you can correlate cost with delivery milestones before the invoice arrives.

The daemon buffers locally and flushes to the cloud API every 60 seconds. These numbers are never more than a minute behind reality.

Instrument 03

How it lines up with the provider invoice.

The numbers your daemon computes from your LLM API calls, reconciled against the totals each provider charges you at month-end. Targeted variance is <1% — anything over and the workspace flags it for review.

05 · Enterprise · self-hosted Cloud

When the data can't leave
the building.

Some workloads come with data-residency requirements that no public SaaS can satisfy. Halton Meter ships as a self-hosted distribution — the same backend and dashboard, running in your VPC under your keys, with no traffic routed through Halton Labs infrastructure.

  • Data residency Your VPC, your keys

    Deploy via Helm chart or Terraform module. Postgres, the API server, and the dashboard all run inside your perimeter. No outbound data. No shared tenant infrastructure.

  • Identity SAML, SCIM, audit log

    Connect Okta, Azure AD, or JumpCloud via SAML 2.0. Provision and deprovision teams automatically via SCIM. Every login, export, and policy change lands in an append-only audit log.

  • Support Dedicated channel, SLA

    Shared Slack channel with direct access to the engineering team. 99.9% uptime SLA on the hosted components. Annual security review with findings report.
