CI/CD workflows have become streamlined and AI support has improved collaborative development
We are using GitHub because it is open-source software, which is the most valuable solution for us. The open source and community support are very good. We are always up-to-date with the community, and integration difficulty is very low. If you integrate any CI/CD solutions on GitHub, it's very easy. We started using GitHub about three months ago with AI integration. For our deployments, some developers can be very shy about asking for descriptions on their commits. We are using AI support for comments and deployment management, which is beautiful. We are not using the GitHub API for automating workflows in our projects. I give GitHub a five-star rating for the review capabilities. I also give GitHub five stars for integration with third-party applications. There is a lot of integration available on GitHub. If you want to integrate something, even if it could be integrated before GitHub, you can make your code and integrate your own in-house applications. It's a very easy and powerful aspect of GitHub.

Difficult to use, not efficient, but stable
We are using IBM Rational ClearCase in Peru at two large banks for a code repository. However, it is not meant to be used as a repository 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.  I have…

Quotes from Members

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

Pros

"I appreciate saving from Visual Studio Code that implements changes directly on GitHub."
"This solution is just easy to use."
"I use this solution to store my code in a repository so we can manage version control which is useful."
"The best feature is the ability to track the history of all code changes, and it's easy to use. Additionally, as it's open source, anyone can use that feature resulting in distributed development. This opens the door to collaboration with different code and developer, feature, and master branches of development."
"GitHub's source code management is top-notch. It's easy to inspect changes and visualize code and differences. Their action system is comprehensive in terms of making changes and automation."
"The code versioning is excellent, and having a detailed log, including every change made to the code by every developer, is invaluable. It makes it so that if there is a bug or problem in the product channel, we can find exactly where it happened and how to fix it."
"If you want to share documents, you can create articles and diagrams with GitHub and share."
"GitHub Actions, specifically in the DevOps field, have been extremely valuable."
"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."
"ClearCase integrates well with other engineering tools and frameworks such as the Eclipse environment."
"IBM Rational ClearCase is a stable solution. I have not had any difficulty with reliability."
 

Cons

"The UI is a little outdated, so that could be improved."
"It is currently only from the development perspective. It doesn't have features related to project management and testing. It is not like Azure. So, there is a lot of room for improvement. It is a version control product, and it would be good if they can come up with a complete DevOps product."
"The project management sector really needs some improvement for GitHub. I don't know if GitHub made sense for me as a project manager."
"The GUI design is poor, so I exclusively use the CLI, which is much easier to use and understand. It would be great to see the GUI updated to be more user-friendly."
"If we have complex branch strategies, it becomes very complicated to manage all those branches."
"There is room for improvement in terms of interface."
"The initial setup requires heavy documentation which can be challenging for new developers."
"We want to incorporate management comments within GitHub, making it more like a product management tool. We haven't done that yet. Another change we're considering is migrating from GitHub to Azure DevOps, especially now that Microsoft has introduced it."
"The solution's UI is slow compared to other tools. It is an old tool."
"The protection needs to be improved."
"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."
 

Pricing and Cost Advice

"I think, in terms of price, GitHub is okay compared to other tools."
"We pay a licensing fee for GitHub, which could be cheaper."
"We are currently paying nothing for GitHub."
"If I consider the market standards, the product's price is pocket-friendly."
"The private repositories are free, which is very good."
"I use the free version of the tool."
"I am using the free version of the solution. However, there are some costs my organization pays."
"The tool offers a free program. As you go, you can upgrade from the community version to the professional one. I believe it costs about ten dollars per person, per month."
"This is a very expensive product."
"IBM Rational ClearCase, like any other IBM tool, is expensive."
