Integrated code tracking has streamlined our development workflows and supports project visibility

The biggest benefit I see from Bitbucket Server is that it is providing all the features which Git is providing. Bitbucket Server is using Git as a source code main tool, and it has all the features that any source code repository can provide. A plus point is that we can install it on-premises and manage it easily. Using Bitbucket Server helps me easily track my code changes and where they belong, which saves a lot of time and effort. Without Bitbucket Server, it is very difficult to track the code and changes. The integration with Jira helps me personally with project tracking because Bitbucket Server is a source code repository. We have our SDLC lifecycle in Jira. Every change or every feature request is created as a ticket in Jira, and this ticket is linked with Bitbucket Server repository. Any changes to the code linked to that feature will go to the repository, and we can track that this is the code changed by this feature.

"IBM Rational ClearCase is a stable solution. I have not had any difficulty with reliability."

"Therefore when we started using ClearCase, it was like a miracle."

"ClearCase integrates well with other engineering tools and frameworks such as the Eclipse environment."

Cons

"Bitbucket Server can experience performance issues when pushing a large amount of code. This process may take a considerable amount of time."

"Instead of providing only raw features and plugins, Atlassian should provide a ready-to-use integration of both choices to incorporate "trunk-based" development."

"The product interface consists of multiple features that are complicated to navigate for new users."

"Bitbucket Server installation is a little bit complicated, and it requires vendor support most of the time."

"Instead of providing only raw features and plugins, Atlassian should provide a ready-to-use integration of both choices to incorporate "trunk-based" development."

"Bitbucket Server has limited user support for its free version. It is expensive."

"It is a Java application and runs its own SSH server, and that means that there is a certain overhead on your system."

"The solution comes as a part of the suite."

"We opted for the on-premises solution, and while it's quite expensive, I believe there's room for improvement in terms of pricing. The licensing is based on the number of users, but I'm not entirely certain about the details."

"One needs to pay towards the licensing charges associated with the product."

"Bitbucket Server is quite expensive compared to other products."

"There is a cost to use this solution but it is based on how many users are using it. If you have 50 users or 1,000 users the price will be very different."
