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

"Now Klocwork has completely removed this and we are very easily checking our internal standards."
"The most valuable feature is the Incremental analysis."
"First will be the on-the-fly analysis as it is reducing the time for developing code and report generation."
"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."
"It's integrated into our CI, continuous integration."
"I like not having to dig through false positives. Chasing down a false positive can take anywhere from five minutes for a small easy one, then something that is complicated and goes through a whole bunch of different class cases, and it can take up to 45 minutes to an hour to find out if it is a false positive or not."
"Klocwork has caught up to Fortify and surpassed them; they have a higher detection and false positive rate than Fortify does."
"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."
"The solution provides a good comprehensive debugging feature that I like and which is easy to use."
"The latest AI features and tab completion features are good."
"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."
"The solution has a great debugging feature."
"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 best feature of PyCharm is that it gives you hints whenever it detects any issues while you are coding. This is important because it helps us code faster and without any errors."
"The solution has a nice environment and extensions that make it easy to develop software."
"PyCharm is saving me time and money in general."
 

Cons

"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."
"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."
"There are some false warnings found which eventually are not considered for a fix after the team reviewed the source code."
"Klocwork sometimes provides too many additional warnings which require expertise to manage."
"Every update that we receive requires of us a lengthy and involved process."
"Customers using different static analysis tools report more issues than with Klocwork, indicating that Klocwork's engine is not as superior."
"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."
"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 breakpoints could be improved as they are not that intuitive to use."
"There should be support for the RUST plugin in the Community edition for debugging."
"They give some functionality to use Python Notebook, but it's not great."
"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."
"Notebooks in PyCharm is not as intuitive as it could be."
"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."
"A potential area of improvement in PyCharm at this point would be memory efficiency."
 

Pricing and Cost Advice

"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."
"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."
"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."
"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 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."
"The community edition is free, which is good."
"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."
