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.

Quotes from Members

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

Pros

"Technical support is quite good."
"Using Klocwork, we have cleared all these issues without much difficulty."
"Klocwork is a good product, but keep in mind that before building the code you have to get a report."
"It saves a lot of time when it comes to finding defects, it's basically inputted in every access we do."
"First will be the on-the-fly analysis as it is reducing the time for developing code and report generation."
"One can increase the number of vendors, so the solution is scalable."
"We consider it a stable product."
"I really like Klocwork's server client build because it allows collaboration between the team members."
"The most valuable feature of ReShaper is that it provides continuously scanning of the data in real-time. ReShaper has a really good mechanism and process, they have a decent system."
"Once you get used to working with the ReShaper, you can't get enough of it."
"It comes with many features and supports almost all of the coding languages available."
 

Cons

"For an improved product, we'd like to see integration with Agile DevOps and Agile methodologies."
"Every update that we receive requires of us a lengthy and involved process."
"Global variables sometimes generate false positives. Variables with global scopes sometimes produce false positives, which is annoying and time consuming because I get violations from Klocwork which after personal analysis turn out to be not true."
"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."
"This solution could be improved if they offered support of more languages including Ada and Golang. They currently only support seven languages."
"Support for AUTOSAR C++14 by adding a new taxonomy that you can use to ensure compliance with the AUTOSAR C++14 Standard, release 18-03."
"Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case."
"Klocwork has to improve its features to stay ahead of other free solutions."
"When it's integrated with a weak server machine, the performance isn't that great. It starts up slowly and even crashes at times."
"ReShaper could improve by increasing the performance of the scans. Their application is taking too much CPU. The processing is taking too many CPU resources which causes the system to slow down."
 

Pricing and Cost Advice

"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."
"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 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."
"Licensing fees are paid annually, but they also have a perpetual license."
"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."
"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."
"As far as I know, the licensing isn't very cheap."
