Features, pricing, ratings, and pros and cons, compared head to head.
password_compat is a free static application security testing tool. Perforce Klocwork is a commercial static application security testing tool by Perforce Software. Compare features, ratings, integrations, and community reviews side by side to find the best static application security testing fit for your security stack. Independent and vendor-neutral: we never sell rankings.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
PHP developers maintaining legacy applications need password_compat to backport modern password hashing functions to older PHP versions without rewriting authentication logic. With 2,135 GitHub stars and active maintenance, it's the standard for teams running PHP 5.3–5.4 that can't upgrade immediately but must implement bcrypt or argon2 hashing. Skip this if you're on PHP 5.5 or later; the native password functions are built in and don't require a compatibility layer.
Development teams shipping C, C++, and Java at scale will get the most from Perforce Klocwork because its differential analysis mode catches regressions in changed code without slowing down the build pipeline. It supports MISRA C/C++ and AUTOSAR C++ 14 out of the box, which matters if you're embedded systems or automotive; most SAST tools treat safety standards as an afterthought. Skip this if your codebase is predominantly Python or JavaScript and you need deep data flow analysis for third-party dependencies, where Klocwork's strength in compiled languages becomes a liability.
