Gonzo

Gonzo processes log streams as they arrive from standard input, files, or the network, with native integration for streaming pod logs directly from a Kubernetes cluster and first-class support for the OpenTelemetry log format, including a built-in gRPC server that receives logs over OTLP. It automatically detects JSON, logfmt, and plain-text formats, or a custom format can be defined with YAML configuration, and tracks severity with color-coded distribution charts.

Its k9s-inspired terminal dashboard shows real-time charts for word frequency, attributes, severity, and time, supports both keyboard and mouse navigation, and can pause the whole dashboard while continuing to buffer logs in the background. Pressing a key from any view launches a companion local, browser-based dashboard with workspaces, pattern detection, and severity heatmaps built on the same underlying log stream. It is written in Go and MIT licensed.
