The customer support team is very responsive, proactive, and engages in conversations to ensure our needs are met.
During the initial phase, there was a need for follow-ups and clarifications.
I would rate the technical support for SonarQube Server (formerly SonarQube) as a 10 because we have not faced any specific issues that required us to contact tech support, which is a very rare case.
The community support is quite effective.

I would rate the stability of this solution a nine on a scale of 1 to 10 where one is low stability and 10 is high.
Installation is easy, and the solution is stable.
I think SonarQube Server (formerly SonarQube) is stable, and we did not face any problems unless there was a power outage or if the LAN cable was plugged out.
 

Room For Improvement

Checkmarx One needs enhanced false positive reduction, language support, CD integration, pricing, UI, reporting, and automation improvements.
Klocwork needs improved language support, flexible reporting, better integration with Agile DevOps, and enhanced static and dynamic analysis.
SonarQube Server needs better issue detection, usability, language support, integration, customizable features, and AI-driven dynamic testing enhancements.
It could suggest how the code base is written and automatically populate the source code with three different solution options to choose from.
Klocwork should be able to analyze large codebases efficiently, supporting a desktop version for periodic small delta changes before pushing to the server.
We would like Klocwork to connect to Git and notify developers of issues tied to specific commits.
Klocwork sometimes provides too many additional warnings which require expertise to manage.
Currently, it should also be able to analyze the code and generate and fix the code for specific developers or features that the developers are tracking.
If I fix some vulnerabilities today, they reappear in the next scan, and there will be completely different issues that need to be fixed.
 

Setup Cost

Checkmarx One offers high quality and performance, though its pricing varies and is often seen as expensive yet competitive.
Klocwork's flexible pricing models are valued, though opinions vary on cost-effectiveness, catering to diverse organizational needs.
SonarQube Server provides cost-effective solutions for code quality, with competitive pricing and enhanced features for various project sizes.
It is less expensive than Coverity.
The solution is not very cheap, however, it is less expensive than Coverity.
Klocwork's pricing seems attractive, as it uses a per-user license model that does not have a lot of overhead.
I would rate the pricing for SonarQube Server (formerly SonarQube) as an 8, where 1 is very cheap and 10 is very expensive, because Coverity is very expensive, and while SonarQube is not cheap, it is still less expensive than Coverity.
They always offer around a two-year contract, but we always take a one-year contract because it's expensive.
The freemium version of SonarQube Server offers excellent value, especially compared to the high costs of Snyk.

Syed Hasan - PeerSpot reviewer
Partner experiences excellent technical support and seamless initial setup
In my opinion, if we are able to extract or show the report, and because everything is going towards agent tech and GenAI, it would be beneficial if it could get integrated with our code base and do the fix automatically. It could suggest how the code base is written and automatically populate the source code with three different solution options to choose from. This would be really helpful.
AnirbanSarkar - PeerSpot reviewer
Lets you find defects during the development phase, so you don't have to wait till the development is over to find and address flaws
What needs improvement in Klocwork, compared to other products in the market, is the dashboard or reporting mechanisms that need to be a bit more flexible. The Klocwork dashboard could be improved. Though it's good, it's not as good as some of the other products in the market, which is a problem. The reporting could be more detailed and easier to sort out because sorting in Klocwork could be a bit more time-consuming, mainly when sorting defects based on filters, compared to how it's done on other tools such as Coverity. What I'd like added in the next release of Klocwork is the peer code review Cahoots which used to be a part of Klocwork, and the architecture analysis and both have been taken out of Klocwork. I found the two critical for specific deployments, so if those can be brought back to Klocwork, that would be very good.
Sthembiso Zondi - PeerSpot reviewer
Consistent improvements in code quality and security with effective integration and reliable technical support
The features of SonarQube Server (formerly SonarQube) that I find most useful are the suggestions received from reviewing the code. When they review the code, they provide suggestions on how to fix it, and we find those very useful from a development perspective. We use SonarQube Server's (formerly SonarQube) centralized management and visualization of code quality metrics on the dashboard because that's the executive dashboard that we send to the executives to show where we are in terms of quality, security, and where the company can improve. We use that for organizational improvement purposes. The ability to tailor metrics tracking in SonarQube Server (formerly SonarQube) has been beneficial to my team. There are team-specific dashboards which are related to specific repositories they utilize, and we have that aggregative dashboard that shows the whole organization's performance. We can drill down per specific repository, which makes it easier for the team to improve specific things.
