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.
Wang Dayong - PeerSpot reviewer
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

"There is a central Klocwork server at our headquarter in France so we connect the client directly to the server on-premises remotely."
"Klocwork's most valuable feature is the static code analysis feature. It detects the potential problem earlier to allow the developer to receive feedback quickly and then address it before it becomes a problem."
"We like using the static analysis and code refactoring, which are very valuable because of our requirements to meet safety critical levels and reliability."
"Technical support is quite good."
"It's integrated into our CI, continuous integration."
"I like not having to dig through false positives. Chasing down a false positive can take anywhere from five minutes for a small easy one, then something that is complicated and goes through a whole bunch of different class cases, and it can take up to 45 minutes to an hour to find out if it is a false positive or not."
"The tool helps the team to think beforehand about corner cases or potential bugs that might arise in real-time."
"The ability to create custom checkers is a plus."
"The most valuable features are the wide array of languages, multiple languages per project, the breakdown of bugs, and the description of vulnerabilities and code smells (best practices)."
"If code coverage is a low number then that's of great value to me."
"With SonarQube's web interface, it is easy to drill down to see the individual problems, but also to look at the project from above and get the big picture, with possible larger problem areas."
"SonarQube is good in terms of code review and to report on basic vulnerabilities in your applications."
"The integrations SonarQube provides with our software delivery pipeline are very seamless."
"We have the software metrics that SonarQube gives us, which is something we did not have before. This helps us work towards aiming coding standards to empower us to move in the direction of better code quality. SonarQube provides targets and metrics for that."
"We are using the Community edition. So, we don't have to incur any licensing costs. This is the best part."
"Issue Explanations: Documentation with detailed samples. Helps in growing technical knowledge and re-writing logic to conforming solutions."
 

Cons

"Under NIST cybersecurity standards, we must address vulnerabilities within a specified time after discovering them. When we try to propagate those updates and fixes through the system, it would be nice if the clients could reconnect to the existing server or have the server dynamically updated in some way. I know that isn't easy, but maybe processes could be enhanced to make that more streamlined from a DevOps perspective."
"There are too many warnings, and it requires expertise to determine the correct category for them."
"We'd like to see integration with Agile DevOps and Agile methodologies."
"Klocwork has to improve its features to stay ahead of other free solutions."
"I believe it should support more languages, such as Python and JavaScript."
"Klocwork sometimes provides too many additional warnings which require expertise to manage."
"Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case."
"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."
"SonarQube can improve by scanning the internal library which currently it does not do. We are looking for a solution for this."
"SonarQube could be improved with more dynamic testing—basically, now, it's a static code analysis scan. For example, when the developer writes the code and does the corresponding unit test, he can cover functional and non-functional. So the SonarQube could be improved by helping to execute unit tests and test dynamically, using various parameters, and to help detect any vulnerabilities. Currently, it'll just give the test case and say whether it passes or fails—it won't give you any other input or dynamic testing. They could use artificial intelligence to build a feature that would help developers identify and fix issues in the early stages, which would help us deliver the product and reduce costs. Another area with room for improvement is in regard to automating things, since the process currently needs to be done manually."
"A better design of the interface and add some new rules."
"We've been using the Community Edition, which means that we get to use it at our leisure, and they're kind enough to literally give it to us. However, it takes a fair amount of effort to figure out how to get everything up and running. Since we didn't go with the professional paid version, we're not entitled to support. Of course that could be self-correcting if we were to make the step to buy into this and really use it. Then their technical support would be available to us to make strides for using it better."
"It requires advanced heuristics to recognize more complex constructs that could be disregarded as issues."
"Our developers have complained about the Quality Gates and the number of false positives that this product reports."
"There is need for support for the additional languages and ease of use in adding new rules for detecting issues."
"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."
 

Pricing and Cost Advice

"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."
"This solution offers competitive pricing."
"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."
"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."
"Licensing fees are paid annually, but they also have a perpetual license."
"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."
"Klocwork should not to be quite so heavy handed on the licensing for very specific programs."
"The solution is cheaper than other products."
"Can try developer version for 14 days on the free trial."
"We did not purchase a license (required for C++ support), but this option was considered."
"We are using the Developer Edition and the cost is based on the amount of code that is being processed."
"SonarQube price is a little bit higher than Kiuwan's. Kiuwan also gives a little bit of flexibility in terms of pricing."
"The licence is standard open source licensing"
"We pay €10 per month for this solution, which is good. It provides a good value for money."
"This solution is free."
