Gonzo

Gonzo is an open-source terminal UI for real-time log analysis, featuring k9s-style navigation, regex filtering, and AI-powered insights for log streams.

Gonzo is an open-source terminal user interface designed for real-time log analysis. It allows users to pipe log streams from sources like Kubernetes, AWS CloudWatch, Vercel, Supabase, and OpenTelemetry directly into their terminal. The interface includes k9s-inspired navigation, pattern detection, heatmaps, and regex filtering to help identify issues without switching contexts. Users can invoke AI-powered insights using OpenAI, Claude, or local models via Ollama to generate root cause suggestions on log lines. Pressing a key opens Dstl8.Lite, a local browser dashboard that provides additional visualization and workspace management for the same log streams. The tool requires no account and operates locally on the machine.
