Who is BuildStream toolset for?

BuildStream targets application software developers and system integrators who require an integration tool which is simple enough to be installed locally to build a simple change in an application that is under heavy development and, at the same time, powerful and robust enough to build complex systems at scale as part of a Continuous Delivery based corporate service.

Why should I use BuildStream?

The motivation behind the development of BuildStream is to create a modern continuous integration tool suitable for corporate environments where applications and systems needs to be maintained for some for a long term. At the same time the daily usage of the tool needs to be cost effective, not just during development but also during maintenance stages so BuildStream combines flexibility and power through highly configurable features and good dosis of automation.

BuildStream might be an interesting option to those who like to build their systems and applications getting several outputs like packages, images or containers, from a single set of definitions and instructions, reducing maintenance efforts. BuildStream is also a tough contender in environments where complex integration workflows are required as well as in organizations that have adopted continuous delivery principles.
