An easy to use modern Java bytecode editor that abstracts away the complexities of Java programs. Recaf abstracts away:

• Constant pool
• Stack frames
• Wide instructions
• And more!

Don't know bytecode? That's ok because Recaf supports recompiling decompiled code and inserting single line Java statements into the bytecode.

See the releases page for the latest build.
