Remill review
A focused C++ library for lifting supported binaries into LLVM IR.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Remill is an open-source library for reverse-engineering and binary-analysis tooling. It translates supported machine-code instructions into LLVM intermediate representation, giving developers a normalized form to process in custom static translation workflows. The project is aimed at engineers building analysis frameworks, decompilers, or other LLVM-based tooling rather than users seeking a complete graphical reverse-engineering application. Its supported instruction sets are x86, x86-64, and AArch64.
The published project is free and self-hosted, with source distributed for a CMake-based build. Linux and macOS are the listed platforms, and the reusable C++ library model fits teams that want to embed instruction lifters and runtime semantics into their own analysis software. Community support and documentation are the listed support channels. There is no separate hosted service or paid plan structure to evaluate, so deployment and maintenance sit with the adopting team.
Remill’s main strength is focused depth in machine-instruction lifting: architecture-specific lifters produce LLVM IR that can be passed into broader static analysis or decompilation pipelines. That focus also defines its boundary. The project does not supply dynamic analysis, a standalone reverse-engineering GUI, or a built-in decompiler, and its platform and architecture coverage is limited to the published set. Choose Remill when you need a programmable LLVM-based lifting component; choose a broader reverse-engineering application when you need an integrated interface, runtime analysis, or wider platform coverage.
Remill pros and cons
- Where it wins
- Lifts x86, x86-64 and AArch64 instructions to LLVM IR
- Reusable C++ library for static binary translation tooling
- Open-source, self-hosted distribution with no paid tier
- Where it doesn't
- Supports only Linux and macOS platforms
- Provides static lifting, not dynamic analysis
- No standalone GUI or built-in decompiler
