Introducing new features

Ship AI agents to production. Stay in control.

CustOS gives development teams full visibility into their AI agents — costs, behavior, security — without the MLOps complexity.

Used by teams building production AI agents. No MLOps experience required.

Who it's for

Built for the teams building agents. Not for ML research labs.

You're shipping AI agents fast. You don't have time to become an observability engineer. CustOS plugs into your stack in minutes and gives you the visibility you actually need: what your agents are doing, what they're spending, and when something goes wrong.

For You

Connects to your
entire AI ecosystem

CustOS integrates with the tools your agents already use — with MCP-powered connections to Gmail, Drive, Slack, GitHub, Notion, and more. Monitor every tool call, in one place.

Observability See exactly what your agents are doing

Full trace of every agent action, LLM call, and decision — in real time. Debug faster, understand behavior, and stop flying blind in production. Supports EU AI Act Article 12 (automatic event logging)

Safety guardrails Keep agents within boundaries

Define what your agents can and cannot do. Detect prompt injections, anomalous behavior, and enforce usage policies. Supports EU AI Act Article 14 (human oversight)

Cost Control Know what you're spending before it hurts

Track token usage and API costs per agent, per user, per workflow. Set budgets, get alerts, and stop surprise invoices at the end of the month.

Anomaly detection Know issues before your users do

Automatically detect abnormal patterns across your agents — cost spikes, latency degradation, error rate surges, and silent agents that stop responding — so you can act before it impacts production. Supports EU AI Act Article 9 (risk management)
