The Boost C++ Libraries are open source, peer-reviewed, portable and free

Created by experts to be reliable, skillfully-designed, and well-tested.

Boost Mission
  • development of high quality, expert reviewed, legally unencumbered, open-source libraries,
  • inspiring standard enhancements, and
  • advancing and disseminating software development best practices.

It does this by fostering community engagement, nurturing leaders, providing necessary financial/legal support, and making directional decisions in the event of Boost community deadlock.

Equally important to our mission is the guidance provided by our shared values. These are transparency, inclusivity, consensus-building, federated authorship, and community-driven leadership.

Why Use Boost?   In a word, Productivity. Use of high-quality libraries like Boost speeds initial development, results in fewer bugs, reduces reinvention-of-the-wheel, and cuts long-term maintenance costs. And since Boost libraries tend to become de facto or de jure standards, many programmers are already familiar with them.

Improving libraries through Boost review process: the case of OpenMethod

Posted on Sep 4th, 2025 by Jean-Louis Leroy

Since 2013, I have been working on libraries that implement open multi-methods
in modern C++. After releasing the first one - YOMM11 - I asked on the Boost
mailing list if there was an interest in bringing YOMM11 into Boost. Back then
there was not much.

I made another attempt when I released the much improved YOMM2, but interest was
still feeble. Or maybe I did not explain what it was about well enough.

Anyway, I continued improving YOMM2 as a stand-alone project, and, in
retrospect, I now think that…
