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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The product’s most valuable features are private repositories and the ability to work as a proxy for implementing CI/CD pipelines."

"Stash really helped us to introduce a very granular permission system for our software repositories."

"Bitbucket Server supports code collaboration by providing commands developers can use to check in code. Through comments, developers can specify the purpose of the code check-in. Additionally, Bitbucket allows tagging of code for releases."

"The most valuable feature is that it has its own pipelines."

"Bitbucket Server integrates well with other products."

"The product is easy to maintain."

"The most valuable feature of this solution is server management, and this is a solution that the global IT department has available for everyone across the organization."

"The platform's most valuable features are the code reviews and the ability to add comments to the code."

More Bitbucket Server pros

"The features allowed us to meet requirements for SOX and set a centralized guideline for our development teams."

"The tool had features similar to Git for version control. It offered branching and merging capabilities, providing better control over code management. Integration was possible with other tools, including some change management tools. The overall process was normal."

"What I like most is that it is very stable."

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

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

"I really appreciate the MultiSite feature; it is important to us due to the global nature of our company, as my team supports developers using ClearCase in at least ten locations worldwide."

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

Cons

"If I want to mail someone a master branch, then sometimes it shows some conflict with other codes in the master branch."

"There are certain functions still missing that are needed to scale it out to a wider set of users and product lines."

"There are absolutely things that could be improved in collaboration features in Bitbucket Server, with respect to people who are not using it every day, such as managers who need to be able to approve things but don't use Bitbucket Server so often."

"The product's initial setup phase is complex."

"Bitbucket Server can be expensive and they want you to purchase their cloud solution."

"We opted for the on-premises solution, and while it's quite expensive, I believe there's room for improvement in terms of pricing."

"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 response time of the product's support team may not be good enough to meet the expectations of users, making it an area where improvements are required."

More Bitbucket Server cons

"Customer service is mediocre. Technical support is mediocre."

"Look for a more modern product. Your suppliers and developers will be happier."

"IBM's support of ClearCase is slipping."

"I have found it very difficult to understand many functionalities in IBM Rational ClearCase. We have had many problems and it is not user-friendly."

"This is an expensive product and the price could be reduced."

"The solution's UI is slow compared to other tools. It is an old tool."

"The protection needs to be improved."

Pricing and Cost Advice

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

"The platform offers a free version for public repositories, which benefits open-source projects."

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

"The tool's licensing costs are yearly. Prices can become expensive if you have a lot of users."

"As for licensing, Bitbucket is one of the more affordable options."

"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."

"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."

"This is a very expensive product."

"IBM Rational ClearCase, like any other IBM tool, is expensive."
