Inner source is the idea of using open source techniques to develop internal tools, using platforms such as GitHub for collaboration. Engineers across a company identify common issues and technologies and work together to build a single solution to all their problems. It’s an important technique that can significantly reduce duplicate effort. One major bank went from using more than 10 versions of a grid control to just one.
But what happens to a mature inner source project that could be beneficial outside the organization that created it? Some remain behind closed doors, but others make the leap to open source.
