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

"Overall, it's a very good product."
"We use GitHub as a repository."
"It’s great to find the talent who is available and has particular skills."
"If you're looking for storing files and code, GitHub is the best and most secure solution."
"It provides Draft Pull Requests for review purposes without needing immediate merging and GitHub Actions for CI/CD implementation."
"Even if I'm not in the office, I can access and work on my code from anywhere with my account credentials."
"GitHub is specifically designed for repositories and it works perfectly for storing code; we use it for our source code repository."
"It's beneficial for managing multiple tasks and controlling versions of your product."
"What I like most is that it is very stable."
"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, 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."
"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."
"The features allowed us to meet requirements for SOX and set a centralized guideline for our development teams."
 

Cons

"The solution needs some more controls for deleting code."
"It is difficult to merge a code or restore it to an older version."
"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."
"The solution lacks sufficient support in terms of professional services that could be provided proactively to customers."
"This solution could be improved by offering crowd sourced support where we could ask questions to other users."
"We face issues with synchronization while working with teams."
"GitHub could add more security features. I am not sure how secure it is. If they provide more security features, then it can be used in more official applications."
"It would be useful to have tutorial videos within the GitHub dashboard."
"IBM's support of ClearCase is slipping."
"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."
"The solution's UI is slow compared to other tools. It is an old tool."
"This is an expensive product and the price could be reduced."
"Look for a more modern product. Your suppliers and developers will be happier."
"Customer service is mediocre. Technical support is mediocre."
"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

"GitHub is an open-source application. It's free to use."
"I use the free version of GitHub."
"GitHub is a cost-effective solution."
"The private repositories are free, which is very good."
"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."
"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."
"There are no licensing fees for the features that we use."
"If I consider the market standards, the product's price is pocket-friendly."
"This is a very expensive product."
"IBM Rational ClearCase, like any other IBM tool, is expensive."
