What it does

Infer is a static analyzer that automatically checks for bugs in Java, C, C++, and Objective-C code, helping developers catch issues before they cause problems.

When to use it
  • •When you're working on a large codebase and want to identify potential issues before they become bugs
  • •When you're integrating third-party libraries and want to ensure they don't introduce security vulnerabilities
  • •When you're refactoring code and want to verify that changes haven't introduced new errors

Heads up: Make sure you have opam (the OCaml package manager) installed before attempting to install Infer, as it is required to manage dependencies
