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.

Boost presence at WG21 meeting in Sofia, Bulgaria

Posted on Jun 25th, 2025 by Robert Beeston

The C++ Alliance, one of the sponsors of the recent WG21 meeting in Sofia, Bulgaria, has brought some Boost posters and merchandise to the event. It's been a nice opportunity to share with the commitee members information on some of the newest Boost libraries and the launch of our new website. On the standardization front, the long-awaited inclusion of reflection in C++26 has been making the rounds across the community.

Try to guess who's who in the pictures below! Cheers!
