Gonzo

Gonzo is an open source, Go-based terminal UI for real-time log analysis. It lets developers and SREs analyze live log streams directly in the terminal using an interactive dashboard with charts, filters, and structured views. It supports multiple input sources, including files, stdin, and OpenTelemetry streams, while automatically detecting formats such as JSON and logfmt. Users can explore logs through a k9s-inspired layout, combining visualizations like heatmaps, severity distributions, and timelines. Advanced filtering with regex and attribute search helps isolate issues quickly. Gonzo also integrates AI capabilities to detect patterns, highlight anomalies, and suggest root causes, making it easier to understand complex system behavior. With customizable themes, keyboard and mouse navigation, and support for local or external AI models, it provides a fast, developer-friendly way to turn raw logs into actionable insights without leaving the terminal.
