## What it is
A logging infrastructure library for Go with customizable output formats and support for multiple backends such as syslog, file, and memory. It allows different log levels per backend and logger, with colored formatter support.

## Use cases
- add structured logging to a Go application
- send logs to multiple backends with different levels
- customize log output format with colors
- redact sensitive values in log messages
- route error-level logs separately from debug logs

## When to choose
- you need flexible multi-backend logging in Go
- you want per-backend log level control
- you need customizable, colored log formatting

## When to avoid
- you need a library with an active backwards-compatibility promise
- you want a logging solution under active heavy development
- you prefer the standard library log or slog with no extra dependencies

## Facets
- artifact type: library
- maturity: maintenance
- function: logging
- domain: developer-tools, backend
- platform: go, windows, cross-platform
- tags: go, log-backends, syslog, format-strings, log-levels, linux, macos
