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.

Gives access to documentation references when hovered over the code

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 significantly improved my coding efficiency with its feature that shows documentation when I hover over code. This feature, which was recently introduced, is especially useful when using an inbuilt function from a Python package because it gives me immediate access to documentation and references, helping me understand how to use the function properly.

Quotes from Members

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

Pros

"There is a central Klocwork server at our headquarter in France so we connect the client directly to the server on-premises remotely."

"On-the-fly analysis and incremental analysis are the best parts of Klocwork. Currently, we are using both of these features very effectively."

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

"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."

"Technical support is quite good."

"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."

"The most valuable feature is the Incremental analysis."

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

More Klocwork pros

"PyCharm is saving me time and money in general."

"The solution has a great debugging feature."

"The integrated code structure makes coding more organized and manageable compared to using Python alone."

"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 product's IDE feature is quite user-friendly."

"The solution has a nice environment and extensions that make it easy to develop software."

"Good syntax highlighting and very it's very customizable."

"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

"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.

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."

"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."

"We'd like to see integration with Agile DevOps and Agile methodologies."

"Under NIST cybersecurity standards, we must address vulnerabilities within a specified time after discovering them. When we try to propagate those updates and fixes through the system, it would be nice if the clients could reconnect to the existing server or have the server dynamically updated in some way. I know that isn't easy, but maybe processes could be enhanced to make that more streamlined from a DevOps perspective."

"This solution could be improved if they offered support of more languages including Ada and Golang. They currently only support seven languages."

"Klocwork has to improve its features to stay ahead of other free solutions."

"Klocwork sometimes provides too many additional warnings which require expertise to manage."

More Klocwork cons

"Notebooks in PyCharm is not as intuitive as it could be."

"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 navigation can be better."

"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."

"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."

"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."

"There should be support for the RUST plugin in the Community edition for debugging."

Pricing and Cost Advice

"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."

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

"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."

"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 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."

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

"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."

"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."

"I don't have much info on the pricing, but I would say it is somewhat competitive."

"The price is reasonable."

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

"I use the free community version, so I'm saving money there."
