Semgrep vs SecuNexa
Semgrep earned real developer affection by making static analysis rules easy to write and fast to run: patterns that look like the code they match. SecuNexa approaches the same problem from the opposite end: deep structural analysis over data flow. The trade-off between writability and depth is the honest center of this comparison.

Pattern rules versus taint analysis: does the difference matter in practice?
It matters exactly when code stops looking like the examples: wrappers, indirection, and team idioms. A useful evaluation exercise is rewriting a known-vulnerable snippet in an unfamiliar idiom and checking which tool still finds it, with what evidence.
