Hermes Bytecode Decompiler
 

A powerful decompiler that lets you reverse-engineer React Native mobile apps by converting their compiled Hermes bytecode (.hbc) files back into readable JavaScript.

This is a Rust decompiler for Hermes bytecode (.hbc), the JS engine behind React Native. Supports HBC 40 to 99.

Full flags and examples → docs/USAGE.md.

Notes:

• Full-bundle decompile uses an on-disk .hdcache for fast reloads. Pass --no-cache to force.
• Write tools patch bytecode / HASM. They do not recompile decompiled JavaScript.
• decompile -o … prints pipeline stages on stderr.
