# Tessary self-hosting docs

> Introduce Tessary self-hosting docs and route readers to the setup, configuration, deployment, upgrading, and troubleshooting pages.

Tessary's open edition is an open-source agent reliability platform. It ingests every trace an agent produces, runs cheap classifiers against each one to create findings, groups related findings into cases, and runs an agentic RCA (root-cause analysis) to explain what caused each case.

This documentation covers self-hosting the open-source product with Docker Compose. It does not cover Tessary Cloud, the SaaS-hosted product.
