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.

Advanced machine learning workflows have become faster but still need better memory efficiency
In PyCharm, I find several components and libraries to be the most valuable. The support that Jupyter Notebook offers is essential, as we work through Jupyter regularly. Scientific libraries such as NumPy, Pandas, Matplotlib, and Plotly are integral to our work. Machine learning libraries including scikit-learn, PyTorch, and TensorFlow are used extensively. Hugging Face integration is particularly valuable because it is easily findable, the documentation is comprehensive, and it can be directly integrated with the IDEs we work with. The intelligent code editor in PyCharm definitely helps me manage code quality and efficiency in my projects. When using these libraries, it makes parallelization of data very efficient, allowing me to use multi-thread programming architecture. The code can work for multiple datasets rather than one at a time. With native Python code, a machine learning deployment taking 45 to 50 minutes to calculate can be efficiently reduced to a minute or half a second using these libraries.

Quotes from Members

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

Pros

"Unlike other static code analysis tools, Klocwork integrates seamlessly into desktop IDEs, build systems, continuous integration tools, and any team's natural workflow."
"The whole package offers a lot of possibilities: add-ons for Eclipse, standalone clients, access via web site, support, documentation, command line."
"Using Klocwork, we have cleared all these issues without much difficulty."
"Now Klocwork has completely removed this and we are very easily checking our internal standards."
"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."
"Klocwork is a good product, but keep in mind that before building the code you have to get a report."
"The ability to create custom checkers is a plus."
"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."
"The solution has a great debugging feature."
"The recent AI-powered code completion is pretty cool."
"The integrated code structure makes coding more organized and manageable compared to using Python alone."
"The solution has a nice environment and extensions that make it easy to develop software."
"Good syntax highlighting and very it's very customizable."
"PyCharm is saving me time and money in general."
"The latest AI features and tab completion features are good."
"We have integrated the tool with GitHub. PyCharm provides easy integration with GitHub, allowing us to push changes directly. Many plugins are available on PyCharm for GitHub integration, including GitHub Copilot for auto code completion and GitHub Copilot Chat for assistance with code-related queries."
 

Cons

"Even though it does the job, there's room for feature enhancements, such as integrations with Git for better tracking and notifications."
"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."
"There are too many warnings, and it requires expertise to determine the correct category for them."
"Modern languages, such as Angular and .NET, should be included as a part of Klocwork."
"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."
"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."
"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."
"They should improve the product's interactiveness."
"PyCharm's use of system resources can get pretty heavy. Loading, in particular, takes longer than I would like and I think they should optimize it so that it's a bit lighter on the system."
"The solution does not support some features of OpenCV even though it is part of a PyCharm package."
"The navigation can be better."
"They give some functionality to use Python Notebook, but it's not great."
"The refactor facility in PyCharm is not on par with the refactor facility in IntelliJ. It could be improved since IntelliJ offers many more options for refactoring."
"There should be support for the RUST plugin in the Community edition for debugging."
"The solution is heavy because running it on laptops consumes a lot of memory and power. Typically, a laptop battery might last about eight to nine hours, but with the tool running, it reduces to two hours or one and a half hours at most. It is designed to handle large projects and heavy tasks, making it resource-intensive. For smaller projects, use IDEs like Visual Studio Code."
 

Pricing and Cost Advice

"This solution offers competitive pricing."
"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 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."
"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 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 community edition is free, which is good."
"I use the free community version, so I'm saving money there."
"The price is reasonable."
"I don't have much info on the pricing, but I would say it is somewhat competitive."
"The community edition is free and the professional edition has a licensing fee."
"They have a free Community edition, and they also have a licensed version. They definitely have an annual license. They probably also have a monthly license. Its pricing is good and reasonable. It is a little bit more expensive than the others, but it is well worth it. I would rate it a four out of five in terms of pricing."
