Observability and cost intelligence for AI coding agents
See how your AI agents work. Understand what drives the cost.
Ottto reconciles local agent sessions with subscription, API, and cloud billing evidence—so you can connect agents, recurring work, repositories, models, and context to cost.

Why Ottto
AI coding work no longer fits in one prompt—or one bill.
A root agent launches reviewers and testers. Scheduled jobs repeat. Skills and tool schemas consume context. Work crosses machines, repositories, models, subscriptions, APIs, and cloud accounts. Provider bills show totals; Ottto connects those totals back to the work.
Recurring work
Group repeated runs by supported schedule, template, or title evidence.
Context footprint
Compare composition and posture across repositories and machines.
Mixed billing
Keep subscriptions, metered APIs, credits, and cloud costs distinct.
How Ottto works
Collect. Reconcile. Review.
Ottto observes alongside supported tools. It never sits in the model-call path.
Collect
Gather the evidence each connected source can provide: Local enriched activity, optional Live telemetry, integrations, and cloud billing.
Reconcile
Join supported sessions, accounts, machines, repositories, plans, usage, and bills while preserving source and billing basis.
Review
Turn reconciled evidence into reviewable recommendations with an impact basis, caveats, safeguards, and a clear next step.
Recurring work
Turn repeated runs into a workload you can inspect.
Ottto groups recurring work from supported schedule, template, and title evidence. See each group’s cadence, tokens, cost, models, machines, and run history—before the pattern disappears into a monthly total.
- ✓
Evidence defines the group. Repetition is a pattern; it is not proof that a run was automated.
- ✓
Runs remain inspectable. Open any group to review the sessions behind it.
- ✓
Unknown stays unknown. Missing origin is labeled “No automation evidence,” not guessed as “human.”

No automation evidence remains a separate, visible remainder whenever supported origin facts are absent.
Agent families
Trace cost across a delegated task’s recorded agent family.
Agent Families links a starting session to the agents it launched, showing each run’s cost and where lineage evidence is incomplete. Switch among Map, Timeline, List, and Details without losing your place.

Each supported edge names its provider or launcher evidence. Missing or truncated lineage stays visible.

Context intelligence
See what fills the context window.
See what enters context, how it persists across later turns, and how the footprint changes by repository and machine. Measurement boundaries distinguish what is observed, modeled, or unavailable.

Context composition
Break down startup instructions, file reads, tool output, browser captures, memory, and delegated-agent results.
Context posture
Compare startup, growth, measured peaks, pressure bands, and recorded compactions.
Memory & tool footprint
Review repository memory files and configured MCP tool-schema context by supported agent and machine.
Cost intelligence
Connect how agents run to how you pay.
Break supported spend down by tool, model, session, repository, source, and billing path. Keep subscription fees, metered APIs, credits, quota windows, and cloud bills distinct so one total never hides different cost bases.
- ✓
Charges stay charges. Provider-reported overage stays separate from flat fees and what-if equivalents.
- ✓
Unknown limits stay unknown. Missing quota windows are omitted instead of shown as zero.
- ✓
Coverage stays visible. Partial, stale, unsupported, and still-learning states remain part of the answer.
