Welcome to Boost.org!

The Boost web site provides free, peer-reviewed, C++ libraries. The emphasis is on portable libraries which work well with the C++ Standard Library.

Library Requirements and Guidelines and Library Submission Process provides basic information for library authors.

If you are interested in who writes the libraries and maintains the web site, check out people.

The FAQ answers questions we hope someone will bother to ask.

You may download all of boost as a single ZIP file. Click here for download details. The source code is also publicly accessible in a CVS repository.

See Compiler Status to find out what library works with which compiler.
