Infer Static Analyzer | Infer | Infer
A tool to detect bugs in Java and C/C++/Objective-C code before it shipsInfer is a static analysis tool - if you give Infer some Java or C/C++/Objective-C code it produces a list of potential bugs. Anyone can use Infer to intercept critical bugs before they have shipped to users, and help prevent crashes or poor performance.
