🐱 DataCat – Observability Platform

DataCat is an open-source observability platform designed for real-time monitoring and analysis of distributed systems. It provides integrated tools for working with metrics, logs, and traces, along with flexible alerting, notification, and visualization capabilities.

The system consists of two main components:

• DataCat Server (Backend) — a .NET-based core responsible for data processing, alerting, and integrations.

• DataCat UI (Frontend) — a web interface for managing alerts, dashboards, notifications, and telemetry exploration.
