jclasslib is a desktop GUI tool that visualizes and edits compiled Java class files and their bytecode, including constant pool entries and instructions. It also ships a Kotlin Multiplatform library for programmatically reading and writing JVM class files.

Use cases

• inspect java bytecode of compiled class files
• edit constant pool entries in a class file
• view bytecode of a kotlin or groovy file inside intellij
• read and write java class files programmatically
• understand what the compiler generated for my java code

When to choose

• you need a visual, interactive viewer and editor for JVM class files and bytecode
• you want an IntelliJ IDEA plugin to inspect bytecode of the open file
• you need a library to parse or generate Java class files from Kotlin, Java, or JS

When to avoid

• you need a decompiler that produces readable Java source code
• you only need quick javap-style output in the terminal without a GUI
• your project cannot accept GPL-licensed dependencies
