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

"The most valuable feature is the fact that it's cloud-based, and we don't have to manage an on-premises server to use it."
"I like the CI/CD features."
"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."
"Has great integration with third-party tools."
"The most valuable feature of the solution is the version control field."
"I find GitHub's pull request strategies and GitHub Actions to be very valuable."
"The tool is valuable because it helps us work in a distributed environment with multiple people across different locations and time zones. We have a common repository that everyone works on, which would be tough to manage manually. GitHub helps us maintain this single source of truth. Everyone can check out their own branches, which is important for our branching strategies. We can fork, check out feature branches, work on our code, and merge back into parent branches for deployment. This is crucial when multiple people are working on the same codebase."
"All the features are valuable, but the most important feature is that GitHub has advanced security. The second important feature is the capability to create custom GitHub actions and the capability to deploy in different types of architectural infrastructures, such as hybrid, private, or public."
"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."
"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 documentation needs to be more concise and easier for developers to understand."
"Regarding improvements, I preferred the tool's earlier pricing model, which limited storage and the number of repositories instead of the number of users, which was more convenient from a customer perspective. I've also experienced issues with GitHub servers being unable to support moving repositories, which caused problems. For basic plans, no support was available to help resolve these issues. I think GitHub should provide more support for smaller businesses to help with these problems."
"It would be useful to have tutorial videos within the GitHub dashboard."
"GitHub could improve by being more user-friendly."
"I would want to see some form of code security scanning implemented."
"I would like a more graphical, user-friendly UI, to avoid writing so much code on cmd."
"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."
"The protection needs to be improved."
 

Pricing and Cost Advice

"My company purchased it. Before, we used to receive the free version, but then they purchased some of the features."
"We are currently paying nothing for GitHub."
"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."
"You don't have to pay for a license if you are using the free version."
"I use the free version of the tool."
"There are no licensing fees for the features that we use."
"The licensing model from GitHub is very clear."
"This is a very expensive product."
"IBM Rational ClearCase, like any other IBM tool, is expensive."
