Rainbow Brackets for IntelliJ is a plugin for IntelliJ-based IDEs that colorizes matching brackets and parentheses in source code.
The plugin addresses the difficulty of tracking nested brackets and parentheses in complex code by assigning different colors to each nesting level. Matching pairs receive the same color, making it visually obvious which opening and closing brackets correspond to each other. This approach works across multiple programming languages supported by IntelliJ-based editors.
The tool suits developers working in IntelliJ IDEA, Android Studio, HUAWEI DevEco Studio, or Fleet who spend significant time reading and editing code with deep nesting. It is particularly valuable in languages like Clojure, Scala, and Java where nested structures are common. The plugin integrates directly into the IDE's syntax highlighting system, requiring no external configuration to function.
Development activity shows consistent maintenance across the supported platforms. The project maintains separate plugin versions for IntelliJ-based IDEs and for Fleet, indicating active effort to keep pace with the Jetbrains ecosystem. The codebase is written in Kotlin, aligning with modern Jetbrains tooling practices.
