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

"The tool helps the team to think beforehand about corner cases or potential bugs that might arise in real-time."
"Now Klocwork has completely removed this and we are very easily checking our internal standards."
"There's a feature in Klocwork called 'on-the-fly analysis', which helps developers to find and fix the defects at the time of development itself."
"On-the-fly analysis and incremental analysis are the best parts of Klocwork. Currently, we are using both of these features very effectively."
"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."
"The best advantage of Klocwork is the reduced setup time."
"Technical support is quite good."
"Klocwork has reduced the manual analysis for a lot of scenarios like checking for internal standards and has saved a lot of time in developing code through the on the fly analysis mode."
"Once you get used to working with the ReShaper, you can't get enough of it."
"The most valuable feature of ReShaper is that it provides continuously scanning of the data in real-time, and ReShaper has a really good mechanism and process, with a decent system."
"It comes with many features and supports almost all of the coding languages available."
"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."
 

Cons

"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."
"Every update that we receive requires of us a lengthy and involved process."
"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."
"I believe it should support more languages, such as Python and JavaScript."
"There are too many warnings, and it requires expertise to determine the correct category for them."
"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."
"I believe it should support more languages, such as Python and JavaScript."
"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."
"When it's integrated with a weak server machine, the performance isn't that great. It starts up slowly and even crashes at times."

Pricing and Cost Advice

"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."
"Klocwork should not to be quite so heavy handed on the licensing for very specific programs."
"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."
"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."
"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."
"This solution offers competitive pricing."
"Licensing fees are paid annually, but they also have a perpetual license."
"As far as I know, the licensing isn't very cheap."
