Bitbucket Server vs GitHub Enterprise

It's easy to create pull requests through the different view options and commenting. Stash also offers code reviews via pull requests, leading to better code quality.

Stash uses JIRA for issue tracking and integrate out-of-the-box with Bamboo and Hitchat. Furthermore, it has many third party integrations and comprehensive API points for custom tools and integration.

Stash installation is very easy and there are install wizards for Windows, Linux and OSX. There are also a lot of tutorials and guides that cover the installation process and more.

Stash is built with focus on enterprise teams, as such it can scale up to 5000 users on a single instance, it is flexible enough to deploy to multiple OS and has multiple backing stores and database options.

Stash is backed and developed by Atlassian, an established and world-class software company with a great history of customer support.

Stash has a permissions system that has 4 levels that go down to branch level.

1. Global Permissions: Decide who can log in, who the system admin is, etc...
2. Project Permissions: Read, write, and admin permissions at the project level.
3. Repository Permissions: Read, write, and admin permissions on a repository level.
4. Branch Permissions: Access and write(push) on a branch level.

In Stash, pull requests are visible to all team members, but they can only be approved for merging by a limited number of globally set reviewers.

Works fully on Linux and with limitations on Windows and OS X. It also has installers that will make the installation easy for each of them.

GitHub's UI is clean and intuitive. Each view is designed to not fill the screen with useless information.

For example, the repository view displays only the most crucial data about that repo - on the top it displays the number of commits, branches, releases and contributors. When clicked, each of them will take the user to a page that displays more detailed information.

GitHub enterprise is available for Amazon AWS, VMware and now on OpenStack KVM as well.
This facilitates the use of GitHub Enterprise for people already familiar with these platforms and allows teams to keep using their infrastructure of choice.

When linked to JIRA, branches, commit messages and pull requests can all reference JIRA issues. This allows JIRA to display information about your development activity in the corresponding issue.

GitHub Enterprise has powerful search features that allow users to search by file name or project name. It's one of GitHub's most powerful tools.

GitHub has improved the LDAP performance. By optimizing searching strategies, they have reduced significant network IO and total queries. Therefore, in some cases as much as 40 percent less data is transmitted on sign on.

Gists are ways to share code or have conversations about anything without needing a full git repo, and still, they work as git repos so they are versioned, forkable and usable from git.

GitHub does not render just markdown, it also renders geojson files, 3D models and csv files.

With GitHub Enterprise edits to code files and to files in general can be made inline right on the web page UI.

There is an option to test GitHub Enterprise for free for 45 days.
