Executive SummaryUpdated on Dec 19, 2024

Klocwork and ReShaper are competing products in the software development tools market. Klocwork seems to have an edge in pricing and customer support, while ReShaper is favored for its robust features.

Features: Klocwork's strength is in static code analysis and bug detection for C, C++, Java, and C#, with a focus on catching critical security vulnerabilities early. Its main feature is the emphasis on security and compliance. ReShaper is known for improving code quality in .NET environments with comprehensive refactoring capabilities and real-time code suggestions. Its feature set emphasizes coding efficiency and support across multiple languages and development environments.

Ease of Deployment and Customer Service: Klocwork offers on-premises deployment, requiring configuration and maintenance, which can be time-intensive. It provides responsive customer service with structured support channels. ReShaper integrates seamlessly with IDEs, ensuring straightforward deployment and offers efficient self-service support through its extensive community and documentation resources.

Pricing and ROI: Klocwork involves higher upfront setup costs but delivers substantial ROI through reduced security risks and minimized code rework. ReShaper has a more accessible pricing model with quick time-to-value by boosting productivity from day one. With better pricing and support, Klocwork is beneficial; however, ReShaper's features and ease of deployment offer a quicker ROI, appealing to budget-conscious teams focused on productivity.

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.

Detects, analyzes, and fixes any coding issues
When it's integrated with a weak server machine, the performance isn't that great. It starts up slowly and even crashes at times. If they optimized some of the modules within the ReSharper extension, it would be smoother and faster. Sometimes when the machine is a bit overloaded, it causes it to crash and you need to disable the extension and then re-enabled it. It's not really a stability issue, it probably depends on the machine, but they should consider the fact that not all people have strong machines with high hardware specifications. As long as you have a good processor it will work smoothly, but regarding minimum requirements, it needs to be revisited.

Quotes from Members

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

Pros

"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."
"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."
"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."
"The most valuable feature of Klocwork is its reduced setup time."
"It's integrated into our CI, continuous integration."
"The most valuable feature of Klocwork is its reduced setup time."
"The best advantage of Klocwork is the reduced setup time."
More Klocwork pros
"It comes with many features and supports almost all of the coding languages available."
"The most valuable feature of ReShaper is that it provides continuously scanning of the data in real-time. ReShaper has a really good mechanism and process, they have a decent system."
 

Cons

"Klocwork sometimes provides too many additional warnings which require expertise to manage."
"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 has to improve its features to stay ahead of other free solutions."
"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."
"I would like to see better codes between projects and a more user-friendly desktop in the next release."
"Every update that we receive requires of us a lengthy and involved process."
"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."
"We'd like to see integration with Agile DevOps and Agile methodologies."
More Klocwork cons
"When it's integrated with a weak server machine, the performance isn't that great. It starts up slowly and even crashes at times."
"ReShaper could improve by increasing the performance of the scans. Their application is taking too much CPU. The processing is taking too many CPU resources which causes the system to slow down."
 

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."
"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."
"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."
"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."
"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."
"Licensing fees are paid annually, but they also have a perpetual license."
"As far as I know, the licensing isn't very cheap."
