LLVM is a set of compiler and toolchain technologies that can be used to develop a frontend for any programming language and a backend for any instruction set architecture. LLVM is designed around a language-independent intermediate representation (IR) that serves as a portable, high-level assembly language that can be optimized with a variety of transformations over multiple passes. The name LLVM originally stood for Low Level Virtual Machine. However, the project has since expanded, and the name is no longer an acronym but an orphan initialism.
LLVM is written in C++ and is designed for compile-time, link-time, and runtime optimizing. Originally implemented for C and C++, the language-agnostic design of LLVM has since spawned a wide variety of frontends: languages with compilers that use LLVM (or which do not directly use LLVM but can generate compiled programs as LLVM IR) include ActionScript, Ada, C# for .NET, Common Lisp, Crystal, CUDA, D, Delphi, Dylan, Forth, Fortran, FreeBASIC, Free Pascal, Halide, Haskell, Idris, Jai (only for optimized release builds), JVM bytecode (Java), Julia, Kotlin, G (in LabVIEW), Objective-C, OpenCL, Odin, PicoLisp, PostgreSQL's SQL and PL/pgSQL, Ruby, Rust, Scala, Standard ML, Swift, Wolfram Language, Xojo, and Zig.
What is LLVM?
LLVM by LLVM (developed by Chris Lattner) is open-source Windows software in the languages & sdks category. It ranks 2nd by popularity among languages & sdks in this catalogue. The first release dates back to 2003. It is written in C++, C, and assembly language. Besides Windows, it is available for cross-platform, NetBSD, FreeBSD, OpenBSD and Linux.
Installation and requirements
The publisher provides MSI installers for 64-bit and ARM64 Windows. A silent install is possible with the installer’s documented switches. An MSI package is available for deployment with Group Policy, Intune or Configuration Manager.
Updates and version history
The current version is 23.1.4, released on October 20, 2026. The version history goes back to March 30, 2021: 77 releases, all linked to the official files. That is about 14 releases a year. The last update is less than a month old.
Popularity and file types
The Chocolatey package has been downloaded 2,833,618 times. The source code on GitHub (llvm/llvm-project) has 41,155 stars. Wikipedia has an article about it in 25 of our languages. Similar programs include Go Programming Language, CMake and Deno.
Project description on GitHub: “The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.”
Pros / Cons

Is LLVM safe to download?
- The file is served by github.com, the publisher’s own domain
- The download link uses HTTPS
- A SHA256 hash is published, so you can verify the file:
