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

"It has a lot of features from the code development perspective. You get a lot of features such as repo, commit, merge, and branch. You can play around and do things on the fly. It is easy and simple to deploy. It is also easier to use when working from home."
"GitHub provides enough storage for uploading the source code."
"The solution has been stable for us."
"The support team is good."
"Complication free with good ability for third-party integrations."
"With GitHub, we can manage our development progress, CID, and continuous integration. It helps streamline our development processes effectively."
"GitHub is very straightforward. I really appreciate the versioning capabilities, ease of use, and the ability to host code."
"The most valuable features are the speed, low latency, and the clear, concise set of commands."
"IBM Rational ClearCase is a stable solution. I have not had any difficulty with reliability."
"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."
 

Cons

"It would be beneficial if GitHub provided some security scanning for new libraries to ensure that there are no viruses in it."
"I would want to see some form of code security scanning implemented."
"The development team pushes the code into a repository, and the CI/CD pipeline will perform the build. We need open-source libraries to perform the builds. It would be helpful to have the ability to link to open-source libraries like npm libraries. I don't know if GitHub Actions provides this. I would like to see that in GitHub Actions if they don't."
"I cannot recall coming across any shortcomings of the product."
"We are not able to access GitHub from our VPN."
"I think one area where GitHub could improve is its search and navigation functionality within repositories. For example, we use IDEs like IntelliJ or Visual Studio Code when developing code. These IDEs allow us to easily navigate from one piece of code to another file where a method is being called. It would be really helpful if the solution could add this navigation feature."
"Github needs more storage."
"Though I haven't done much research, GitHub lacks in providing more functions like GitLab."
"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

"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."
"There are no licensing fees for the features that we use."
"I haven't had to pay anything for GitHub, I use the free version."
"If there are only 10 people using a particular repository, then GitHub is free. But if we increase the number of users, we need to pay the normal charge for GitHub."
"I use the free version of GitHub."
"I think, in terms of price, GitHub is okay compared to other tools."
"We are currently paying nothing for GitHub."
"GitHub is a cost-effective solution."
"This is a very expensive product."
"IBM Rational ClearCase, like any other IBM tool, is expensive."
