Conan (software) is an open-source package manager for C and C++ that automates dependency management, binary package creation, and distribution for native development. It targets developers and continuous integration environments seeking reproducible builds, integration with build systems, and cross-platform package workflows across Linux, macOS, and Microsoft Windows. The project interacts with a broad ecosystem of tools and services from build orchestration to artifact repositories and is used by enterprises, open-source projects, and research institutions.

Overview

Conan is designed as a decentralized package manager that supports creating, versioning, and distributing binary and source packages for C++ ecosystems including libraries like Boost (library), OpenSSL, zlib, Qt (software), and Poco (software). It integrates with build systems such as CMake, Meson (software), Bazel (software), SCons, and Ninja (software) while interoperating with compilers including GCC, Clang (LLVM project), and Microsoft Visual C++. The tool distinguishes itself by providing profiles for compiler, architecture, and build type settings, enabling reproducible artifacts for continuous integration platforms like Jenkins (software), GitHub Actions, GitLab CI, Travis CI, and Azure Pipelines.

History and Development

Conan originated in the mid-2010s to address limitations in native dependency management for C++ that projects such as Chromium (web browser), Mozilla Firefox, and LibreOffice faced when scaling build systems. Early development was driven by contributors associated with companies like JFrog and independent maintainers active on GitHub. Major milestones include the adoption of a recipe-based model similar to package managers like Homebrew and APT (Debian), the introduction of multi-revision and lockfile features influenced by Cargo (software), and enterprise-oriented features aligning with artifact repositories such as Artifactory. The project evolved through community proposals, discussions on platforms like Stack Overflow, and contributions from organizations running large C++ codebases such as NVIDIA, Intel, and Microsoft.

Architecture and Components

Conan’s architecture consists of a command-line client implemented in Python (programming language), a package recipe model, and a package storage protocol compatible with artifact repositories. Key components include the conanfile recipe format, package recipes that describe build steps for libraries like Boost (library), the binary package cache, and remote servers such as JFrog Artifactory or self-hosted services. Conan’s model interfaces with C/C++ package metadata and integrates with build toolchains like GNU Make, MSBuild, and Xcode (IDE), and compilers such as Intel C++ Compiler and Oracle Solaris Studio. The client interacts with remotes via RESTful APIs and employs package ID hashing for reproducibility, while lockfiles and graph resolution borrow concepts from package ecosystems like npm and pip.

Package Management and Workflow

A typical workflow uses a conanfile to declare dependencies, build requirements, and non-code artifacts, referencing third-party libraries like SQLite, FFmpeg, OpenCV, Boost (library), and Protobuf. Developers create profiles to pin compiler versions and ABI settings for targets such as x86_64 and ARM architectures used by projects like Raspberry Pi or Android (operating system). The workflow integrates with continuous integration systems including CircleCI and TeamCity (software) to automate building binary packages, uploading them to remotes such as JFrog Artifactory or generic repositories, and consuming them in downstream projects. Dependency graph resolution, package locks, and reproducible builds enable collaboration patterns similar to those in Rust (programming language) and Go (programming language) ecosystems.

Integration and Tooling

Conan provides integrations and plugins for IDEs and platforms such as Visual Studio, CLion, Eclipse (software), and Qt Creator, enabling developers to import dependency sets into project workspaces. It supports generators that produce integration files for CMake, pkg-config, and Autotools, and provides tooling for cross-compilation targeting systems like Android (operating system), iOS, and embedded platforms supported by Yocto Project. Conan can be combined with binary analysis and security scanners from vendors like Sonatype, Snyk (company), and Black Duck (software) to enforce policy and license compliance for components including OpenSSL and libcurl.

Adoption and Use Cases

Conan is adopted by enterprises, research labs, and open-source projects managing complex native dependencies such as Panda3D, Godot Engine, Blender, and robotics stacks like ROS (Robot Operating System). Use cases include reproducible CI pipelines for game development studios, cross-platform SDK distribution for hardware vendors like NVIDIA and AMD, and monorepo dependency management in large organizations such as Facebook and Google where native builds must interoperate with languages and tools like Python (programming language), Java (programming language), and Node.js. Conan’s binary package caching and remote replication features are used to accelerate continuous delivery and reduce build times on cloud platforms like AWS, Microsoft Azure, and Google Cloud Platform.

Licensing and Community Governance

Conan is released under the MIT License and is developed under an open governance model with maintainers and contributors coordinating on platforms such as GitHub, Gerrit, and community forums. The project’s stewardship involves corporate sponsorship from organizations including JFrog and participation by independent contributors from companies such as Red Hat, Sony, and Siemens. Community governance covers roadmap discussions, security disclosures, and acceptance of contributions, with influence from standards and practices used by ecosystems like OpenSSL and LLVM (project). The licensing model facilitates integration into proprietary products and open-source distributions alike.
