ROI

Sentiment score
6.2
Klocwork enhances code quality and compliance, improving efficiency in defect resolution, especially in automotive sectors, despite ROI measurement challenges.
Sentiment score
7.1
SonarQube improves code quality and developer productivity, enhancing long-term efficiency and stability by integrating with CI/CD pipelines.
The main ROI factors include efficiency and how we meet compliance standards for various automotive requirements.
Manager, Quality, Functional Safety, Cybersecurity Embedded Processing at a manufacturing company with 10,001+ employees
It is easily integrable with the CI/CD pipeline and supports multiple projects with its extensive plugin options.
Security Analyst at Dover Corporation
I have seen a return on the investment from SonarQube Server (formerly SonarQube) because the value it adds relates to static code analysis and vulnerability assessments needed for our FDA approval process.
Sr Software Engineering Supervisor at Mozarc Medical
We see productivity increasing based on the fact that the code review is mostly automated, allowing the developer to fix the code themselves before assigning it to someone else to review, thus receiving that ROI.

Sentiment score
6.7
Klocwork is scalable, efficient, and integrates well with SAST tools, suitable for teams of all sizes without scalability issues.
Sentiment score
7.0
SonarQube effectively scales across environments, handling multiple repositories, though performance may lag with large codebases, proving its versatility.
Klocwork supports our scalability needs without issues, even as project volumes increase.
Application Development Team Lead at Miura Pay
The program-to-program enablement is scalable.
Director - Quality Excellence at a manufacturing company with 501-1,000 employees
There are limitations, and it seems to have fewer capabilities than Veracode.
CEO at a computer software company with 1-10 employees
It has been used in multiple projects and performs well.
consultant at a computer software company with 1,001-5,000 employees
I would rate the scalability of SonarQube Server as a 10 because we can configure the server to scan multiple projects based on the number of lines.
Sr Software Engineering Supervisor at Mozarc Medical
 

Stability Issues

Sentiment score
6.8
Klocwork is reliable and stable, effectively handling large codebases but requires significant computing power and faster updates.
Sentiment score
7.7
SonarQube is highly stable, with minor issues largely related to configuration, achieving user stability ratings between seven and ten.
Installation is easy, and the solution is stable.
Integration Supervisor Lead at Visteon Corporation
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.
Sr Software Engineering Supervisor at Mozarc Medical
From my team's feedback, it is almost an eight out of ten.
CEO at a computer software company with 1-10 employees
It is a quite stable solution.
Security Analyst at Dover Corporation
 

Room For Improvement

Klocwork needs improved language support, flexible reporting, better integration with Agile DevOps, and enhanced static and dynamic analysis.
SonarQube struggles with slow analysis, complex setup, inadequate security, language rule issues, and needs better DevOps integration.
There are too many warnings, and it requires expertise to determine the correct category for them.
Integration Supervisor Lead at Visteon Corporation
Klocwork sometimes provides too many additional warnings which require expertise to manage.
Director - Quality Excellence at a manufacturing company with 501-1,000 employees
We would like Klocwork to connect to Git and notify developers of issues tied to specific commits.
Application Development Team Lead at Miura Pay
I would like to see SonarQube Cloud provide more detailed solutions for fixing code issues, especially solutions related to CVEs.
Security Analyst at Dover Corporation
I need a solution that can bring together three key areas: vulnerabilities, static scanning, and misarchitecture.
Architect at sigpsc inc
Static code analysis is good, but the product lacks dynamic code scanning capabilities, an area where Veracode excels.
consultant at a computer software company with 1,001-5,000 employees
 

Setup Cost

Klocwork's flexible pricing models are valued, though opinions vary on cost-effectiveness, catering to diverse organizational needs.
SonarQube provides free and paid versions, with licensing based on code lines; costs vary by features and support.
It is less expensive than Coverity.
Director - Quality Excellence at a manufacturing company with 501-1,000 employees
The solution is not very cheap, however, it is less expensive than Coverity.
Integration Supervisor Lead at Visteon Corporation
Klocwork was competitively priced, making it a cost-effective solution for us.
Application Development Team Lead at Miura Pay
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.
Sr Software Engineering Supervisor at Mozarc Medical
They always offer around a two-year contract, but we always take a one-year contract because it's expensive.
Head of Software Engineering at ronaldmariah@gmail.com
The freemium version of SonarQube Server offers excellent value, especially compared to the high costs of Snyk.
Distinguish Engineer at Gtmhub
 

Valuable Features

Klocwork provides efficient static code analysis with strong IDE integration, supporting multiple languages and enhancing code quality and collaboration.
SonarQube excels with comprehensive language support, customization, integration, and security features, offering user-friendly dashboards and community-driven enhancements.
The most valuable feature of Klocwork is the static analysis tools, which help identify potential security threats and errors.
Application Development Team Lead at Miura Pay
Its integration with the CI/CD pipeline has helped streamline the software development process.
Manager, Quality, Functional Safety, Cybersecurity Embedded Processing at a manufacturing company with 10,001+ employees
It takes just half a day to set up.
Integration Supervisor Lead at Visteon Corporation
Some of the static code analysis capabilities are the most beneficial.
Distinguish Engineer at Gtmhub
I find SonarQube Cloud very easy to use and simple to integrate initially.
CEO at a computer software company with 1-10 employees
It gives precise reports compared to Coverity and has a slightly lower number of false positives.

Manager, Quality, Functional Safety, Cybersecurity Embedded Processing at a manufacturing company with 10,001+ employees
Experience with compliance improvements and efficiency boosts but static analysis engine shows a need for enhancement
One area for improvement is that when customers use different static analysis tools, they report more issues compared to Klocwork. The static analysis engine of Klocwork has areas that need improvement. Customers using different static analysis tools report more issues than with Klocwork, indicating that Klocwork's engine is not as superior. Klocwork should be able to analyze large codebases efficiently, supporting a desktop version for periodic small delta changes before pushing to the server.

Sr Software Engineering Supervisor at Mozarc Medical
Gains control over rule customization and achieves reliable vulnerability assessment
The deployment process took me about 2 or 3 hours to deploy SonarQube Server (formerly SonarQube), although I do not remember exactly since it was done about 2 years back. Currently, about 10 of my developers are using SonarQube Server (formerly SonarQube) in my company. I do not have plans to increase the usage of SonarQube Server (formerly SonarQube) in the future as there will not be any requirement to increase. I am a senior software engineer and supervisor at Mozark Medical. My corporate email address is karthik.k.a.r.t.h.i.k.h.a.r.p.a.n.h.a.l.l.i@mozarkmedical.com. Overall, I would rate SonarQube Server (formerly SonarQube) as a 9 out of 10.
