spdlog is a very fast C++ logging library that can be used header-only or compiled, with formatting powered by the fmt library. It supports asynchronous logging, multiple log targets (rotating/daily files, console, syslog, Windows event log), runtime-adjustable log levels, and backtrace buffering.
Use cases
- add fast logging to a C++ application
- log to rotating or daily files in C++
- asynchronous logging for multithreaded C++ programs
- colored console logging in C++
- header-only logging library for C++11
- write logs to syslog or Windows event log
When to choose
- you need high-performance logging in a C++ project
- you want a header-only option with no dependencies beyond fmt
- you need multiple log sinks like files, console, syslog, or Windows event log
- you want runtime-configurable log levels and backtrace support
When to avoid
- you are not working in C++
- you need structured/JSON logging out of the box without extra sinks
- you require a distributed or centralized logging solution rather than an in-process library
