Dagger is a programmable deployment system.
Using Dagger, software builders can automate the deployment of any application to any infrastructure,
in just a few lines of code.

The Dagger platform adapts to your application, not the other way around.
Thanks to its ecosystem of reusable packages and flexible scripting system, Dagger can be dropped
into any software project without requiring changes to its architecture or workflow.
Think of it as your "devops superglu".

No matter how your deployment works under the hood, you can manage it with the same Dagger user interface.
This makes developers more productive, because they don't have to learn a new workflow every time their deployment

As an application grows, it is almost certain to outgrow the capabilities of a PaaS system, leaving no choice but to look for alternatives. A good strategy is to choose the right platform for each component. Some components continue to run on a PaaS system; others run on specialized infrastructure. This strategy can be implemented with Dagger: each component gets its own deployment plan expressed as code, and Dagger glues it all together into a single workflow.
## Dagger vs. artisanal deploy scripts
*Summary: Dagger can augment your deploy scripts, and later help you simplify or even remove them.*
