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.

Easy to integrate and has a plug-in that supports both C and C++ languages

The product provides false reports sometimes. It also fails to understand the context of the code. It reports that a line of code has issues without considering its relation with the previous line. The product should improve the report quality. While it asks us to improve the code quality, it would be good if it also suggests how to improve the quality.

Quotes from Members

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

Pros

"On-the-fly analysis and incremental analysis are the best parts of Klocwork. Currently, we are using both of these features very effectively."

"The tool helps the team to think beforehand about corner cases or potential bugs that might arise in real-time."

"One can increase the number of vendors, so the solution is scalable."

"We like using the static analysis and code refactoring, which are very valuable because of our requirements to meet safety critical levels and reliability."

"There is a central Klocwork server at our headquarter in France so we connect the client directly to the server on-premises remotely."

"The ability to create custom checkers is a plus."

"The reporting helps us understand the trend of our results and whether we improve over time. We can see the history within Klocwork's server architecture and know that we're making things better. It creates a great story for our management. We can demonstrate value and how our software is developing over time."

"The most valuable feature of Klocwork is its reduced setup time."

More Klocwork pros

"The most valuable features are code scanning and Quality Gates."

"The most valuable features are the segregation containment and the suspension of product services."

"Integrate it into the developers' workbench so that they can bench check their code against what will be done in the server-based audit version."

"The software quality gate streamlines the product's quality."

"SonarQube's unit test coverage and exhaustive information at the module, project, and overall code repo levels are quite good."

"SonarQube is good for checking and maintaining code quality."

"We use this solution for qualitative coding. We make use of the SonarLint plugin as well as the dashboard."

"The reporting and the results are quick. It gets integrated within the pipeline well."

More SonarQube Server (formerly SonarQube) pros

Cons

"Even though it does the job, there's room for feature enhancements, such as integrations with Git for better tracking and notifications."

"Now the only issue we have is that whenever we need to get the code we have to build it first. Then we can get the report."

"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."

"The way to define the rules is too complex. The definition/rules for static analysis could be automated according to various SILs, so as to avoid confusion."

"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."

"This solution could be improved if they offered support of more languages including Ada and Golang. They currently only support seven languages."

"We'd like to see integration with Agile DevOps and Agile methodologies."

"Modern languages, such as Angular and .NET, should be included as a part of Klocwork. They have recently added Kotlin as a part of their project, but we would like to see more languages in Klocwork. That's the reason we are using Coverity as a backup for some of the other languages."

More Klocwork cons

"During the setup process, we only had one issue related to the number of available files. To perform the analysis, you have quite a lot of available file handles, so we had to increase that limit."

"Depending on the tool's configuration, sometimes you get false alarms that are unimportant to you."

"The documentation is not clear and it needs to be updated."

"The implementation of the solution is straightforward. However, we did have some initial initialization issues at the of the projects. I don't think it was SonarQube's fault. It was the way it was implemented in our organization because it's mainly integrated with many software, such as Jira, Confluence, and Butler."

"I don't believe you can have metrics of code quality based upon code analysis. I don't think it's possible for a computer to do it."

"We have tens of millions of code to be analyzed and processed. There can be some performance degradation if we are applying Sonar Link to large code or code that is complex. When the code had to be analyzed is when we ran into the main issues. There were several routines involved to solve those performance issues but this process should be improved."

"SonarQube could be improved by implementing inter-procedural code analysis capabilities, allowing for a more comprehensive detection of defects and vulnerabilities across the entire codebase."

"I would like to see improvements in defining the quality sets of rules and the quality to ensure code with low-performance does not end up in production."

Pricing and Cost Advice

"Licensing fees are paid annually, but they also have a perpetual license."

"The pricing for Klocwork is very competitive if you compare it from apple to apple. It has competitive pricing regarding the licensing model and the per-license cost. Klocwork isn't a high-end investment for anyone deploying it; even SMBs can afford it. The Klocwork cost per user would depend on the license type, so I'm unable to mention a ballpark figure because it would depend on the type of installation and how the deployment will be, and the nodes to give an accurate calculation or figure. The total price depends on the package, so my company could never publish pricing for Klocwork on the website. My team first collects information from potential clients on the deployment scenario, project environment, etc., before suggesting a package for Klocwork. My rating for Klocwork in terms of pricing is a five because of its flexible license models. There's a license model for every type of organization, whether small, midsize, or enterprise, so it's a five out of five for me."

"Klocwork should not to be quite so heavy handed on the licensing for very specific programs."

"Klocwork is still tight on their licensing. If Klocwork would loosen up on the licensing, and where the license could be used, and how many different programs could be run on it, then we have several development programs that I would love to be able to use it for going forward."

"When it comes to licensing, the solution has two packages, one for a fixed and the other for a floating server, with the former being more cost effective than the latter."

"The limitation that we have is that Klocwork is licensed to certain programs, and if you want to license them to other programs, you have to pay more money."

"There are other solutions on the market such as Microsoft Visual Studio. They have been adding more static code analysis features that come for free. It is getting better all the time. That is one of the possibilities is that we've been considering that we may stop using the Klocwork because it doesn't give us any added value."

"This solution offers competitive pricing."

"I do not know about the pricing as I am using the community edition, which is free. But I compared the pricing with Sigma, and it is higher than SonarQube."

"SonarQube price is a little bit higher than Kiuwan's. Kiuwan also gives a little bit of flexibility in terms of pricing."

"SonarQube enterprise, I am not sure of the price but from what I understand they are charging a fee. It's is not clear if it is an annual fee or a one-off."

"We use the tool's community edition."

"Get the paid version which allows the customized dashboard and provides technical support."

"This solution is free."

"The product’s price is lower than Veracode’s price."

"I requested this license for one million lines of code and they accepted this."
