PureCM is an integrated project management, task tracking and version control tool. Based on the concept of changesets that represent tasks, it provides developers with an easy to use and highly transparent GUI to improve teamwork. The Professional edition includes all features, but the Standard edition only includes the version control core, offering a lightweight solution for users looking for a best-of-breed configuration management tool. PureCM outperforms most other SCM tools, uses a reliable SQLite database, and is scalable to thousands of concurrent developers. The server, GUI, command line, and Web clients runs on Linux, Unix, Mac OS, and Windows.
