Flogger is a fluent logging API for Java developed by Google, designed as a unified replacement for the many logging APIs used across large codebases. It offers near-zero cost for disabled log statements, high performance for enabled ones, and an extensible fluent interface that produces self-documenting log calls.

Use cases

  • replace slf4j or java.util.logging in a Java project
  • add high-performance debug logging without overhead
  • write self-documenting log statements with fluent API
  • rate-limit expensive log statements
  • unify logging APIs across a large multi-project codebase

When to choose

  • you want a modern, performant logging API for JVM code
  • you need cheap disabled-level logging with many fine-grained statements
  • you want extensible logging features without multiple façades

When to avoid

  • you are locked into an existing logging framework with heavy integration
  • you work in a non-JVM language
  • you need a logging backend itself rather than an API façade
