Features, integrations, deployment and the company behind each one, side by side. ## Our take What our shortlists say about the one we picked. ### [Perforce Klocwork](https://cybersectools.com/tools/perforce-klocwork) Best for: Safety-critical embedded teams requiring MISRA and AUTOSAR compliance The limitation is that Klocwork's language support is narrower than some competitors: C, C++, C#, Java, JavaScript, Python, and Kotlin. If your stack includes Go, Ruby, Swift, or other languages, you will need a supplementary solution. The hybrid deployment model works for teams with on-premises requirements, but the setup and maintenance burden is higher than a SaaS alternative. This is a solution for teams with dedicated toolchain engineers, not a plug-and-play solution.
