BridgePoint is Open Source Software (OSS). It is free. However, OSS is not free like “free beer”; it is more like “free puppy”. Just like a puppy, open source software requires care and maintenance. Some members of the xtUML Community contribute to BridgePoint by finding and fixing bugs, writing code for new features and helping write documentation.
Other members of the community fund these activities. Usually, it is a company running a project that employs BridgePoint tooling in their development processes.
