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

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

"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."

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

"Klocwork is user-friendly, with a client-server architecture that provides all needed compliance."

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

"The best advantage of Klocwork is the reduced setup time."

"We like using the static analysis and code refactoring, which are very valuable because of our requirements to meet safety critical levels and reliability."

"The most valuable feature is the Incremental analysis."

More Klocwork pros

"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 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."

"It is an excellent, fully integrated IDE with smart code analysis capability and a built-in debugger. It is a fantastic tool."

"The recent AI-powered code completion is pretty cool."

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

"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."

More PyCharm pros

Cons

"Klocwork does have a problem with true positives. It only found 30% of true positives in the Juliet test case."

"I hope that in each new release they add new features relating to the addition of checkers, improving their analysis engines etc."

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

"Now the only issue we have is that whenever we need to get the code we have to build it first. Then we can get the report."

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

"Even though it does the job, there's room for feature enhancements, such as integrations with Git for better tracking and notifications."

"I would like to see better codes between projects and a more user-friendly desktop in the next release."

More Klocwork cons

"The user interface and overall user experience could be more intuitive to make it easier for users to navigate and utilize the software effectively."

"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."

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

"Customizing the tool can make it complicated."

"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."

"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."

More PyCharm cons

Pricing and Cost Advice

"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 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."

"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."

"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."

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

"The community edition is free and the professional edition has a licensing fee."

"The price is reasonable."

"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."

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

"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."
