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 find GitHub very user friendly."
"You can write the code with AI. But when it comes to implementation, you must upgrade the bits of code that will support this and generate solutions based on that architecture. Then, you need comparable code bits. Therefore, AI can propose how much a specific function can be better optimized. So, AI can help stakeholders reach tasks quicker."
"GitHub allows you to create pages, and if you want to share documents you can create articles and diagrams with GitHub and share, and on a personal level, GitHub assists you to create your own website."
"The initial setup was straightforward."
"The most valuable features are GitHub Actions for triggering workflows, GitHub Secrets for saving credentials without needing a third-party service, and the UI for identifying errors in the code when we commit."
"The solution has been stable for us."
"GitHub have a built-in software application development environment and this has been most useful."
"It is really simple to set up."
"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."
"ClearCase integrates well with other engineering tools and frameworks such as the Eclipse environment."
"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."
"Therefore when we started using ClearCase, it was like a miracle."
"IBM Rational ClearCase is a stable solution, and I have not had any difficulty with reliability."
 

Cons

"This solution could be improved by offering crowd sourced support where we could ask questions to other users."
"The query function in GitHub is a bit stiff."
"The customer service for this solution is not great. The team either takes a long time to respond or doesn't respond at all."
"While using the solution when merging two code branches the code becomes a bit messy. This should be improved in the future."
"The project management sector really needs some improvement for GitHub."
"GitHub could have better integration or capability with other solutions."
"The GitHub repository needs an upgraded user interface and overall UI improvements."
"There is room for improvement in terms of interface."
"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 protection needs to be improved."
"IBM's support of ClearCase is slipping."
"This is an expensive product and the price could be reduced."
"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."
"Customer service is mediocre. Technical support is mediocre."
"Look for a more modern product. Your suppliers and developers will be happier."
"The solution's UI is slow compared to other tools. It is an old tool."
 

Pricing and Cost Advice

"GitHub is a cost-effective solution."
"Regarding pricing, I'd rate it eight out of ten. It's decent and not too expensive, and small businesses can also afford it. With AWS taking CodeCommit out of the market, I don't see many competitors for small companies in terms of GitHub."
"It's cheaper than Bitbucket."
"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."
"It’s an open-source solution."
"The private repositories are free, which is very good."
"You don't have to pay for a license if you are using the free version."
"I am using the free version of the solution. However, there are some costs my organization pays."
"This is a very expensive product."
"IBM Rational ClearCase, like any other IBM tool, is expensive."
