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

"Overall I find Klocwork's features superior for our needs."
"The whole package offers a lot of possibilities: add-ons for Eclipse, standalone clients, access via web site, support, documentation, command line."
"The reporting helps us understand the trend of our results and whether we improve over time. We can see the history within Klocwork's server architecture and know that we're making things better. It creates a great story for our management. We can demonstrate value and how our software is developing over time."
"Technical support is quite good."
"It saves a lot of time when it comes to finding defects, it's basically inputted in every access we do."
"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."
"I really like Klocwork's server client build because it allows collaboration between the team members."
"I recommend this tool as one of the best to be used for static analysis and should at least be tried."
"It is an excellent, fully integrated IDE with smart code analysis capability and a built-in debugger. It is a fantastic tool."
"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."
"The solution has a great debugging feature."
"The automated package installation is helpful. I like the code highlighting features. A huge library of plugins is available, including AI coding tools, though I don't use those myself. The debugging tools are good, showing errors and problem lines."
"Good syntax highlighting and very it's very customizable."
"The solution has a nice environment and extensions that make it easy to develop software."
"PyCharm is saving me time and money in general."
"The recent AI-powered code completion is pretty cool."
 

Cons

"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."
"There are many things that can be improved. The code used between projects is one of the very painful points in Klocwork."
"Customers using different static analysis tools report more issues than with Klocwork, indicating that Klocwork's engine is not as superior."
"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."
"This solution could be improved if they offered support of more languages including Ada and Golang. They currently only support seven languages."
"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."
"Klocwork sometimes provides too many additional warnings which require expertise to manage."
"There are too many warnings, and it requires expertise to determine the correct category for them."
"The solution does not support some features of OpenCV even though it is part of a PyCharm package."
"They should improve the product's interactiveness."
"One issue with JetBrains tools, including PyCharm, is their heavy resource usage. They can be slow to start, especially when beginning a new project, as it takes some time to index."
"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."
"They give some functionality to use Python Notebook, but it's not great."
"There is room for improvement in memory usage. It uses too much memory. It can get a bit heavy, especially when you have too many open files and the system becomes very slow."
"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."
"The pricing model for PyCharm is a significant area for improvement. It is currently too high, with a per-seat cost of approximately 200 pounds."
 

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."
"Licensing fees are paid annually, but they also have a perpetual license."
"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."
"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."
"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."
"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."
"I don't have much info on the pricing, but I would say it is somewhat competitive."
"The community edition is free, which is good."
"The price is reasonable."
"I use the free community version, so I'm saving money there."
"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."
