logbby

Logbby is a lightweight, open-source logging library designed for small to medium-sized applications. It focuses on simple integration, low overhead, and reliable delivery of log messages. Logbby provides asynchronous logging, multiple output destinations, and support for structured log data, enabling easy correlation with other observability tools.

The library uses a pluggable transport architecture, where a transport is responsible for writing a log entry to a destination such as the console, a file, or a remote collector. A center API offers standard log levels (debug, info, warning, error) and supports attaching user-defined fields to each entry for structured logging. Transports can be enabled or disabled through configuration, allowing different environments to use different backends without code changes.

Logbby is implemented in several languages, including Python, JavaScript, and Go, with idiomatic APIs for each. Typical usage involves creating a logger, configuring one or more transports, and emitting log records with optional metadata. The library emphasizes ease of use and predictable performance, making it suitable for hobbyist projects and smaller services that do not require the breadth of enterprise logging frameworks.

History and licensing: Logbby emerged as a community project in the early 2020s and is released under an open-source license. It has seen modest adoption in various repositories and is often pitched as a lightweight alternative to larger logging ecosystems. See also: structured logging, log management, log4j, printf logging.
