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.

Quotes from Members

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

Pros

"I recommend using GitHub because it is reliable and helpful for developers."
"There are no issues. It's simple, easy, and fully compatible from my perspective with Git."
"The ease of the planning board feature in GitHub is very valuable."
"With GitHub, we can manage our development progress, CID, and continuous integration. It helps streamline our development processes effectively."
"The flexibility of this solution has been most valuable. It operates on a pay per use basis where you can ramp up or decrease usage."
"It is very helpful, time saving, and user-friendly."
"The most valuable feature is the source code management. It's very helpful and it's a great product."
"Our code is secure."
"ClearCase integrates well with other engineering tools and frameworks such as the Eclipse environment."
"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."
"IBM Rational ClearCase is a stable solution. I have not had any difficulty with reliability."
 

Cons

"The initial setup and implementation could be easier, I had some difficulties with it at first but I don't have a development background."
"Lacks sufficient support in terms of professional services that could be provided."
"The ticketing system is not working."
"The user interface on GitLab is better."
"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."
"GitHub could automate the setup process more, such as creating YAML files for GitHub Actions."
"There could be more integration into Azure."
"The solution's cost is high and should be reduced."
"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 use the free version of GitHub."
"I haven't had to pay anything for GitHub, I use the free version."
"I am using the free version of the solution. However, there are some costs my organization pays."
"GitHub is an open-source product, but when using the free-to-use version, anyone can see the code we're working on."
"The basic licensing model is free, and if you need to have technical support and such things, then it does cost something. You only need to pay extra if you need technical support."
"The private repositories are free, which is very good."
"We are currently paying nothing for GitHub."
"We have an enterprise licensing agreement, and I am not part of the finance department so I can't say how much it costs."
"IBM Rational ClearCase, like any other IBM tool, is expensive."
"This is a very expensive product."
