## What it is
apex/log is a structured logging package for Go, inspired by Logrus and designed with log centralization in mind. It provides a simple API with pluggable handlers for JSON, logfmt, CLI-friendly output, and shipping logs to services like Elasticsearch, Graylog, Kinesis, and Papertrail.

## Use cases
- add structured logging to a Go application
- ship logs to Elasticsearch or Graylog from Go
- format logs as JSON or logfmt
- filter logs by level in Go
- fan out logs to multiple destinations
- human-friendly colored CLI log output

## When to choose
- you want a simple, Logrus-style structured logging API in Go
- you need pluggable handlers for centralized log collection
- you want lightweight logging with field-based context

## When to avoid
- you need a highly active project with frequent updates
- you prefer Go's standard library slog or zerolog/zap performance characteristics
- you need Apex Logs, which is a commercial service

## Facets
- artifact type: library
- maturity: maintenance
- function: logging
- domain: developer-tools, backend
- platform: go, cross-platform
- tags: structured-logging, logrus-inspired, log-handlers, cli-logging
