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.

A reliable solution that provides excellent features and detects memory corruption

The run time analysis process must be improved. If we do not run with the main loop, it generates its own main and doesn’t allow developers to modify the execution sequences. The solution must provide more flexibility to the developers to manipulate the runtime analysis tools. The developer must be allowed to modify the main sequence. It will be very easy for them to test their use cases. Otherwise, Polyspace generates a random main file and executes all the functions randomly.

Quotes from Members

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

Pros

"Klocwork is user-friendly, with a client-server architecture that provides all needed compliance."

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

"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."

"Technical support is quite good."

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

"The most valuable feature of Klocwork is finding defects while you're doing the coding. For example, if you have an IDE plug-in of Klocwork on Visual Studio or Eclipse, you can find the faults; similar to using spell check on Word, you can find out defects during the development phase, which means that you don't have to wait till the development is over to find the flaws and address the deficiencies. I also find language support in Klocwork good because it used to support only C, C++, C#, and Java, but now, it also supports Java scripts and Python."

"The customer support team is very responsive, proactive, and engages in conversations to ensure our needs are met."

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

More Klocwork pros

"Polyspace Code Prover has made me realize it differs from other static code analysis tools because it runs the code. So it's quite distinct in that aspect."

"The product detects memory corruptions."

"Efficiency and speed are the advantages I see in Code Sonar over Polyspace Code Prover."

"Polyspace Code Prover is a very user-friendly tool."

"The outputs are very reliable."

"When we work on safety modules, it is mandatory to fulfill ISO 26262 compliance. Using Prover helps fulfill the standard on top of many other quality checks, like division by zero, data type casts, and null pointer dereferences."

Cons

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

"I would like to see better codes between projects and a more user-friendly desktop in the next release."

"Every update that we receive requires of us a lengthy and involved process."

"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."

"Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case."

"We bought Klocwork, but it was limited to one little program, but the program is now sort of failing. So, we have a license for usage on a program that is sort of failing, and we really can't use the license on anything else."

"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."

"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."

More Klocwork cons

"Because we had difficulties in efficiently integrating Polyspace Code Prover into our CI toolchain, these tests are mostly run manually and only occasionally."

"The tool has some stability issues."

"One of the main disadvantages is the time it takes to initiate the first run."

"Using Code Prover on large applications crashes sometimes."

"I'd like the data to be taken from any format."

"Automation could be a challenge."

Pricing and Cost Advice

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

"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."

"This solution offers competitive pricing."

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

"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."

"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."

"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."

"We use the paid version."

Overview

Klocwork detects security, safety, and reliability issues in real-time by using this static code analysis toolkit that works alongside developers, finding issues as early as possible, and integrates with teams, supporting continuous integration and actionable reporting.

Perforce

Polyspace Code Prover is a sound static analysis tool that proves the absence of overflow, divide-by-zero, out-of-bounds array access, and certain other run-time errors in C and C++ source code. It produces results without requiring program execution, code instrumentation, or test cases. Polyspace Code Prover uses semantic analysis and abstract interpretation based on formal methods to verify software interprocedural, control, and data flow behavior. You can use it on handwritten code, generated code, or a combination of the two. Each operation is color-coded to indicate whether it is free of run-time errors, proven to fail, unreachable, or unproven.
