Tessary

Find and investigate failures in production AI agents

Meet Tessary

Tessary is an observability tool for teams running AI agents in production. It collects execution traces and evaluates behavior to identify problems such as failed tool calls, malformed outputs, and unexpected agent decisions. Engineers can examine the steps of a run instead of relying only on the final response or a user complaint.

The platform groups related failures into cases and helps investigate their causes using trace details and connected code. Configurable classifiers let teams define the behavior they need to watch for. Tessary offers a hosted cloud service with a free allowance as well as a self-hosting option for teams that want to run the platform themselves.
