iced is a fast and correct x86/x64 (16/32/64-bit) instruction decoder, disassembler, and assembler library with bindings for Rust, .NET, Java, Python, Lua, and JavaScript (WebAssembly). It supports all Intel and AMD instructions, multiple formatter syntaxes (masm, nasm, gas/AT&T, Intel/XED), and includes an encoder for re-encoding instructions at arbitrary addresses.

Use cases

• disassemble x86-64 machine code
• assemble instructions programmatically
• decode binary machine code into instructions
• re-encode decoded instructions at a different address
• get instruction info like read/written registers and rflags
• format disassembly in nasm, masm, gas, or Intel syntax
• build a binary analysis or reverse engineering tool

When to choose

• you need a high-performance, thoroughly tested x86/x64 disassembler or assembler
• you need bindings for Rust, .NET, Java, Python, Lua, or JavaScript
• you need instruction metadata such as CPUID feature flags, register/memory access, and control flow info
• correctness matters and you want a library fuzz-tested against xed, gas, objdump, masm, nasm, and ndisasm

When to avoid

• you need to disassemble non-x86 architectures like ARM, RISC-V, or MIPS
• you need a full decompiler or static analysis framework rather than a decoder/assembler
• you need a GUI disassembler like Ghidra or IDA
