FlatLaf is a modern open-source cross-platform Look and Feel for Java Swing desktop applications.
It looks almost flat (no shadows or gradients), clean, simple and elegant. FlatLaf comes with Light, Dark, IntelliJ and Darcula themes, scales on HiDPI displays and runs on Java 8 or newer.
The look is heavily inspired by Darcula and IntelliJ themes from IntelliJ IDEA 2019.2+ and uses almost the same colors and icons.
FlatLaf can use 3rd party themes created for IntelliJ Platform (see IntelliJ Themes Pack):
Run demo with java -jar flatlaf-demo-<version>.jar (or double-click it).
Requires Java 8 or newer.
FlatLaf binaries are available on Maven Central.
If you use Maven or Gradle, add a dependency with following coordinates to your build script:
groupId: com.formdev
artifactId: flatlaf
version: (see button below)
Otherwise download flatlaf-<version>.jar here:
FlatLaf snapshot binaries are available on
Sonatype OSSRH.
To access the latest snapshot, change the FlatLaf version in your dependencies
to <version>-SNAPSHOT (e.g. 0.27-SNAPSHOT) and add the repository
https://oss.sonatype.org/content/repositories/snapshots/ to your build (see
Maven
and
Gradle
docs).
To use FlatLaf, add following code to your main method before you create any Swing component:
FlatLightLaf.setup();
