JEB is a
disassembler
A disassembler is a computer program that translates machine language into assembly language—the inverse operation to that of an assembler. A disassembler differs from a decompiler, which targets a high-level language rather than an assembl ...
and
decompiler
A decompiler is a computer program that translates an executable file to a high-level source file which can be recompiled successfully. It does therefore the opposite of a typical compiler, which translates a high-level language to a low-level l ...

. Users can also write their own scripts and plugins to extend JEB functionality.
Version 2.2 introduced Android debugging modules for Dalvik and native (Intel, ARM, MIPS) code. Users can "seamlessly debug Dalvik bytecode and native machine code, for all apps
..including those that do not explicitly allow debugging".
Version 2.3 introduced native code decompilers. The first decompiler that shipped with JEB was a MIPS 32-bit interactive decompiler.
JEB 3 ships with additional decompilers, including Intel x86, Intel x86-64, WebAssembly (wasm), Ethereum (evm), Diem blockchain (diemvm).
JEB 4 was released in 2021. A RISC-V decompiler was added to JEB 4.5. A S7 PLC block decompiler was added to JEB 4.16.
History
JEB is the first Dalvik decompiler to provide interactive output, as reverse-engineers may examine cross-references, insert comments, or rename items, such as classes and methods. Whenever possible, the correspondence between the bytecode and the decompiled Java code is accessible to the user. Although JEB is branded as a decompiler, it also provides a full APK view (manifest, resources, certificates, etc.). An

The name may be a reference to the well-known security software IDA, as "JEB" =
rot1("IDA").
