Fork vs Gitblit: What are the differences?
Developers describe Fork as "Fast and Friendly Git Client for Mac". Manage your repositories without leaving the application. Organize the repositores into categories. Fork's Diff Viewer provides a clear view to spot the changes in your source code quickly. On the other hand, Gitblit is detailed as "Pure Java Git solution for managing, viewing, and serving Git repositories". Gitblit is an open source, pure Java Git solution for managing, viewing, and serving Git repositories. It can serve repositories over the GIT, HTTP, and SSH transports; it can authenticate against multiple providers; and it allows you to get up-and-running with an attractive, capable Git server in less than 5 minutes.
Fork and Gitblit are primarily classified as "Source Code Management Desktop Apps" and "Code Collaboration & Version Control" tools respectively.
