EasyLogger is an ultra-lightweight, high-performance C/C++ logging library designed for resource-constrained projects like IoT products, wearables, and smart home devices. It supports customizable output backends, dynamic filtering by tag/level/keyword, colored output, async and buffered modes, and extensibility via plugins such as Flash and File logging.

Use cases

• add logging to an embedded firmware with under 2KB ROM budget
• log from a bare-metal microcontroller without an OS
• store logs directly in flash on devices without a filesystem
• filter logs dynamically by tag, level, or keyword at runtime
• output colored logs to a serial terminal
• port a single logging library across RT-Thread, FreeRTOS-like RTOSes, Linux, and Windows

When to choose

• you need logging on resource-constrained embedded or IoT devices
• you want a tiny, fast C logging library with minimal API surface
• you need flash-based log storage without a filesystem
• you need cross-RTOS and bare-metal portability

When to avoid

• you need rich structured logging or JSON output in server-side applications
• you need multiple simultaneous output configurations (it is singleton)
• you want a batteries-included logging ecosystem like log4c or spdlog
• your project is not C/C++
