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.

Seamless integration streamlines tasks and boosts productivity with efficient task handling

PyCharm's utility supports various Python frameworks such as Django and Flask for development projects. Uvicorn is well supported in project creation. Users can choose which framework to create and it handles all the code scaffolding automatically. I use PyCharm Intelligent Code Editor for context-aware code completion, and I also use the new AI extensions that JetBrains provided recently. I find it particularly useful in code refactoring. It saves me time on boilerplate code, such as interaction with the database. I can ask the AI facility in PyCharm to create all the boilerplate code for various databases. I don't write boilerplate code for mundane tasks anymore and focus on the business logic rather than the usual ancillary functions such as collecting records from the database or making network calls. This type of work is all done by AI.

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."

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

"Technical support is quite good."

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

"The most valuable feature of Klocwork is its reduced setup time."

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

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

"It's integrated into our CI, continuous integration."

More Klocwork pros

"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."

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

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

"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 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."

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

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

More PyCharm pros

Cons

"The main problem is that since it only parses the code, the warnings or the problems that are given as a result of the report can sometimes require a lot of effort to analyze."

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

"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."

"There are too many warnings, and it requires expertise to determine the correct category for them."

"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."

"The way to define the rules is too complex. The definition/rules for static analysis could be automated according to various SILs, so as to avoid confusion."

"There are too many warnings, and it requires expertise to determine the correct category for them."

More Klocwork cons

"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."

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

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

"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."

"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 breakpoints could be improved as they are not that intuitive to use."

"The solution does not support some features of OpenCV even though it is part of a PyCharm package."

"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."

More PyCharm cons

Pricing and Cost Advice

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

"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."

"This solution offers competitive pricing."

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

"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."

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

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

"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 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."
