Cargo vs Conan

Cargo is the free package manager and build tool for Rust, used through a command-line interface. It downloads dependencies, builds packages, and supports repeatable builds with lockfiles. Developers can compile, check, document, test, run, package, install, and publish Rust projects. The `cargo new` command creates a package, defaulting to a binary; adding `--lib` creates a library. Cargo uses crates.io by default and also handles alternate registries, Git dependencies, and local paths. Workspaces allow multiple packages to share a lockfile and output directory. Package features can enable conditional compilation and optional dependencies. In offline mode, Cargo avoids network access and attempts to use cached data. It supports authentication options for registries and new subcommands without modifying Cargo itself. Rustup installs Cargo with the stable Rust release, and installation instructions cover Windows, macOS, Linux, and other Unix-like systems. Cargo is open source under the MIT and Apache License, Version 2.0. Some documented capabilities remain unstable and require a nightly toolchain and `-Z` flags.

Conan is a free, open-source package manager for C and C++ projects. It manages dependencies and binary packages through Conan recipes, with dependency resolution, lockfiles, workspaces, private registry authentication and offline installation. Binary configurations can vary by architecture, compiler and version, runtime, and C++ standard library. If a matching binary is unavailable, Conan can build from source on demand. It supports Windows, Linux, macOS, Android, iOS, embedded and bare-metal targets, as well as desktop, server and mobile platforms. Build integrations include CMake, MSBuild, Makefiles, Meson and SCons; other integrations include Docker, MinGW, WSL and JFrog Artifactory. Teams can share and reuse native binaries. Artifactory Community Edition offers self-hosted private package hosting, with a WebUI, authentication and permissions. Conan is released under the MIT License. The listed plan describes the package manager as free and open source; no price is stated for either plan.
