Use searchcode server to promote reuse of existing code and ideas by allowing developers across teams to see how problems were already solved. A few seconds of searching to find something they needed can save hours of implementation and regression testing.

Here are some some user testimonials proving the point,

I wanted to see an example of bluebird promisify and found exactly the example code I needed. The search result and full code views are awesome. An invaluable tool to share code between teams. A great product!

I was looking for an original piece of code which had been copied to another site and used it and it worked perfectly!

I tracked down some code I knew I wrote about about a year ago. We have hundreds of repositories and it literally saved me from hours of busywork. An excellent product.
