Why Logy
Logging tools that stay close to application code.
Named loggers
Create package-based or explicit loggers and keep output tied to the component that produced it.
Context fields
Attach trace IDs, span IDs, request metadata, and other values to logs through context helpers.
Flexible output
Use pattern-based console logs, JSON output, files, syslog, or custom handlers when the runtime needs more.
Fast paths
Keep common logging calls lightweight while still supporting formatted messages and error stack traces.
Configuration
Switch formats without changing call sites.
Configure console output, JSON formatting, handlers, levels, and contextual fields from code or YAML.
