Boosted productivity with automated pipelines and seamless collaboration

There are some challenges with repository file management as GitLab may struggle to manage larger files. Improvements could be made regarding size management and file partitioning. Also, the UI has remained the same for a couple of years and could benefit from an update with AI features and better customization.

Helps us complete testing more quickly by eliminating many unwanted test cases

Sometimes, when we are testing embedded devices, when we trigger the test cases, the target will crash immediately. It is very difficult for us to identify the root cause of the crash because they do not provide sophisticated tools on the target side. They cover only the client-side application, and from that we can generate automated test cases, but what happens on the target device, what is the reason for the crash, for that we have to do manual debugging. They do not have diagnostic tools for the target side. Rather, they have them but they are very minimal and not very helpful. They can improve a lot on that.

Quotes from Members

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

Pros

"The scalability is good."

"GitLab's best features are continuous integration and fast deployment."

"The stability of GitLab is impressive."

"We have seen a couple of merge requests or pull requests raised in GitLab. I see the interface, the way it shows the difference between the two source codes, that it is easy for anyone to do the review and then accept the request; the pull request is the valuable feature."

"The most valuable feature of GitLab is the ability to upload scripts and make changes when needed and then reupload them. Additionally, the solution is user-friendly."

"The CI/CD pipeline with Helm has significantly improved deployment speed and efficiency."

"The code merging capability is something that we use very frequently."

"Continuous integration with deployment is very powerful, which is a significant reason for migrating from TFS to GitLab."

More GitLab pros

"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."

"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."

"Whatever the test suit they give, it is intelligent. It will understand the protocol and it will generate the test cases based on the protocol: protocol, message sequence, protocol, message structure... Because of that, we can eliminate a lot of unwanted test cases, so we can execute the tests and complete them very quickly."

Cons

"Based on what I know so far, its integration with Kubernetes is not so good. We have to develop many things to make it work. We have to acquire third-party components to work with Kubernetes."

"We would like to generate document pages from the sources."

"The documentation is confusing."

"The solution should again offer an on-premises deployment option."

"We do face issues in our company when we run out of disk space."

"We'd always like to see better pricing on the product."

"Merge conflicts and repository maintenance could improve. If there is someone new to the system they would not know if there is a conflict."

"The only thing our company is really waiting on in terms of features is the development of metrics."

More GitLab cons

"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."

"It does not support the complete protocol stack. There are some IoT protocols that are not supported and new protocols that are not supported."

"Sometimes, when we are testing embedded devices, when we trigger the test cases, the target will crash immediately. It is very difficult for us to identify the root cause of the crash because they do not provide sophisticated tools on the target side. They cover only the client-side application... They do not have diagnostic tools for the target side. Rather, they have them but they are very minimal and not very helpful."

Pricing and Cost Advice

"As I work in a vast enterprise, I'm unsure about the licensing cost for GitLab. It's the management team that takes care of that."

"The solution is based on a subscription model and is reasonably priced."

"I think that we pay approximately $100 USD per month."

"The initial setup cost is excellent and you can add the premium features later."

"The solution is based on a licensing model that includes technical support and is paid annually."

"My company uses the free version of GitLab, which is GitLab Community Edition. There is a licensed version also available for GitLab."

"GitLab is highly priced for smaller teams, but it's okay if considering a user base of thousands."

"The solution's standard license is paid annually. They have changed the pricing model and it used to be better. There is a free version available."
