Download of BitKeeper 7.2.1 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The actual developer of this free Mac application is Wayne Scott. The application lies within Developer Tools, more precisely IDE. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe.
From the developer:
BitKeeper is a source management system software. BitKeeper is a fast, enterprise-ready, distributed SCM that scales up to very large projects and down to tiny ones. It offers a hybrid mode for binary files that uses a cloud of server for binaries instead of bloating the source repositories. Also, it is highly accurate auto-merge that uses the whole history to resolve conflicts.
You may want to check out more software for Mac, such as AngelTemplate, ChIDE or EcoLab, which might be similar to BitKeeper.
