  • A thread-safe hash map
  • An Actor framework for simplified design of multi-threaded applications

All products

  • FREE updates — if the library is updated to fix any bugs or improve the conformance with the C++11 and C++14 standards, you will be entitled to a free upgrade to any V2.x release.
  • A royalty free license for a single developer. Once you've purchased a license for each of your developers, you don't need to pay us a penny more, even if you ship a million copies of your application.
  • A 30 day money-back guarantee. If the library doesn't meet your expectations, let us know, and we'll issue you with a refund.

When you purchase your copy of the just::thread library, you will be redirected to a download page from which you can download a Microsoft Windows Installer package for the library (for Windows), or a zip file containing the .DEB/.RPM packages (for Linux). The download for the Portability Bundle is a zip file containing all installers. Save this file, and follow the instructions below to install the library. The link to the download page will also be sent to the email address you supplied to PayPal.


To install the library on Window, double-click the .MSI file in Windows Explorer. To install the library on Linux you can use your favourite package manager, or install from the command line. e.g.

    sudo dpkg -i justthread-gcc4.8-4_2.0.0_amd64.deb
    sudo dpkg -i justthread-gcc4.8-dev_2.0.0_amd64.deb

Why should you use just::thread?

Future Proof your code
With just::thread you can start using the C++11 and C++14 multithreading support today. Rather than using platform-specific APIs you can use standard C++ facilities, making your code more portable both now and in the future.
Detect the cause of deadlocks
With the deadlock-detection debug mode, just::thread can provide you with the complete stack trace of every thread involved in a deadlock. It can also provide the stack trace of the locations where the relevant mutexes were locked. This can dramatically reduce the time taken to track down the cause of such problems and eliminate them. (Not available with the TDM gcc compiler for Windows)
Developed by an authority on C++ multithreading
The just::thread library has been developed by Anthony Williams, author or co-author of many of the multithreading and concurrency-related proposals for C++11. Anthony is also the author of C++ Concurrency in Action, published by Manning, which provides a comprehensive tutorial and reference to the C++11 multithreading facilities.
