Bazel vs Conan: What are the differences?
Bazel: Correct, reproducible, fast builds for everyone. Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google's software, and thus it has been designed to handle build problems present in Google's development environment; Conan: C/C++ package manager. Install or build your own packages for any platform. Conan also allows you to run your own server easily from the command line.
Bazel belongs to "Java Build Tools" category of the tech stack, while Conan can be primarily classified under "Hosted Package Repository".
Some of the features offered by Bazel are:
- Multi-language support: Bazel supports Java, Objective-C and C++ out of the box, and can be extended to support arbitrary programming languages.
- High-level build language: Projects are described in the BUILD language, a concise text format that describes a project as sets of small interconnected libraries, binaries and tests. By contrast, with tools like Make you have to describe individual files and compiler invocations.
- Multi-platform support: The same tool and the same BUILD files can be used to build software for different architectures, and even different platforms. At Google, we use Bazel to build both server applications running on systems in our data centers and client apps running on mobile phones.
On the other hand, Conan provides the following key features:
- Dependencies and package management for developers
- Source code and binaries
Bazel and Conan are both open source tools. It seems that Bazel with 12.4K GitHub stars and 2.02K forks on GitHub has more adoption than Conan with 2.94K GitHub stars and 383 GitHub forks.
According to the StackShare community, Bazel has a broader approval, being mentioned in 11 company stacks & 7 developers stacks; compared to Conan, which is listed in 3 company stacks and 3 developer stacks.
