Loguru is a lightweight, dependency-free C++ logging library consisting of just two files. It offers verbosity levels, assertions, abort handling with cleaned-up stack traces, and user-installable callbacks for custom log output.

Use cases

• add logging to a C++ application with minimal setup
• print stack traces when the program aborts or crashes
• log to multiple files with different verbosity levels
• display severe log messages on-screen in a game or app via callbacks
• replace glog with a faster, simpler logging library

When to choose

• you want a small, fast C++ logger with no dependencies
• you need human-readable, grep-friendly log output
• you want stack traces on fatal errors and signals
• you need custom log callbacks for on-screen display

When to avoid

• you need structured or JSON log output
• you require distributed tracing or log aggregation integrations
• you need async logging with advanced sinks like syslog or logstash
