Watching agents so you don't have to.

agentwach was built after the third time one of our autonomous agents ran up a four-figure model bill overnight. The first time was educational. The second was embarrassing. The third was the moment we accepted that the existing toolchain — flat dashboards, monthly invoices, hand-rolled log greps — was never going to be enough.

Traditional APM tools were built for request/response code paths. Agents do not work that way. A single user prompt can fan out into dozens of model calls, tool invocations, sub-agent delegations, and retries — all orchestrated by a planner that can decide, mid-flight, to try something nobody on the team has ever seen. We needed a control surface designed for that, not a Grafana dashboard with prompts shoehorned in.

What we believe

Watching is not enough. Observability tools that just show you the runaway after the fact are flight recorders. Useful, but late. Real agent infrastructure needs guardrails with teeth — hourly token budgets, daily cost ceilings, loop detection — that can halt a misbehaving agent without paging a human.

Prompt-injection is the SQL-injection of the LLM era. Most teams have no defense deployed in production. We ship a heuristic scanner on every ingest path because the alternative — hoping your model provider catches it — has never worked.

The best infrastructure tools are invisible until they save you. We optimize for the moment at 3am when an agent goes sideways and agentwach has already stopped it, written the incident timeline, and put a row in your warnings inbox. By the time you wake up, the question is "what should we tune?" — not "how much money did we just light on fire?"

What we ship

Four ingest paths (SDK, OpenTelemetry, browser extension, scheduled poller), a unified events and token-usage store, a fifteen-rule security scanner that runs on every event, and a guardrails engine that can stop an agent on the next ingest call. All of it behind a dashboard that gives you one screen to watch your fleet.
