Why tinylog2 Is the Lightweight, Secure Java Logging Solution You Need

What is tinylog2

tinylog2 is an open-source, lightweight logging framework for Java (1.6+), Kotlin, Scala, Android and any JVM language.

Secure and lightweight

tinylog is truly lightweight, consisting of only two JAR files (API and implementation) with no external dependencies, so it is not affected by recent Log4j2 vulnerabilities. The total size is only 178 KB.

Using tinylog2

Logger output

tinylog provides a static Logger class, allowing elegant logging with code such as:

<code>import org.tinylog.Logger;
public class Application {
    public static void main(String[] args) {
        Logger.info("Hello World!");
    }
}
</code>

SLF4J adapter

By adding slf4j-tinylog , you can continue using the SLF4J façade without changing your code, replacing Log4j, Logback, etc.

<code><!--slfj adapter-->
<dependency>
    <groupId>org.tinylog</groupId>
    <artifactId>slf4j-tinylog</artifactId>
    <version>2.4.1</version>
</dependency>
<!--tinylog implementation-->
<dependency>
    <groupId>org.tinylog</groupId>
    <artifactId>tinylog-impl</artifactId>
    <version>2.4.1</version>
</dependency>
</code>

Diverse output options

tinylog2 supports writing log entries to the console, database tables, files, and Android’s logcat. File output supports logback‑style rolling and shared configuration across multiple instances.

Configurable

Configuration is done via a traditional properties file; see the official website for all options. With tinylog2-extra-stuff , you can also configure using YAML or JSON.

<code>writer        = file
writer.file   = application.log
writer.format = {class}.{method}() {message}
level         = info
</code>

Performance

tinylog2 is optimized for fast log entry output and is noticeably faster than other logging frameworks, especially when printing stack trace information such as method names or line numbers.

Open source

Like many Java logging frameworks, tinylog2 is released under the Apache License 2.0 and its source code is hosted on GitHub, free for commercial use.
