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

"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."
"Klocwork's most valuable feature is the static code analysis feature, as it detects potential problems earlier to allow the developer to receive feedback quickly and then address issues before they become a problem."
"Overall I find Klocwork's features superior for our needs."
"It saves a lot of time when it comes to finding defects, it's basically inputted in every access we do."
"We consider it a stable product."
"It's integrated into our CI, continuous integration."
"The most valuable feature is the Incremental analysis."
"Unlike other static code analysis tools, Klocwork integrates seamlessly into desktop IDEs, build systems, continuous integration tools, and any team's natural workflow."
"The solution provides a good comprehensive debugging feature that I like and which is easy to use."
"The solution has a great debugging feature."
"The solution has a nice environment and extensions that make it easy to develop software."
"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."
"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."
"PyCharm has an excellent user experience, and I appreciate its cross-platform capabilities."
"PyCharm is saving me time and money in general."
 

Cons

"For an improved product, we'd like to see integration with Agile DevOps and Agile methodologies."
"The way to define the rules is too complex."
"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 many things that can be improved. The code used between projects is one of the very painful points in Klocwork."
"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."
"Even though it does the job, there's room for feature enhancements, such as integrations with Git for better tracking and notifications."
"I believe it should support more languages, such as Python and JavaScript."
"There are some false warnings found which eventually are not considered for a fix after the team reviewed the source code."
"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 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."
"The breakpoints could be improved as they are not that intuitive to use."
"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 user interface and overall user experience could be more intuitive to make it easier for users to navigate and utilize the software effectively."
"The navigation can be better."
"They should improve the product's interactiveness."
"Notebooks in PyCharm is not as intuitive as it could be."
 

Pricing and Cost Advice

"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."
"Licensing fees are paid annually, but they also have a perpetual license."
"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."
"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."
"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."
"Klocwork should not to be quite so heavy handed on the licensing for very specific programs."
"I don't have much info on the pricing, but I would say it is somewhat competitive."
"I use the free community version, so I'm saving money there."
"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."
"The price is reasonable."
"The community edition is free, which is good."
"The community edition is free and the professional edition has a licensing fee."
