Instead of Infer
Infer alternatives
Infer is a free static analyzer for Java, C, C++, Objective-C, and Erlang. It examines compiled source and reports potential bugs such as null dereferences, memory or resource leaks, unavailable APIs, and data races. Its interprocedural analysis can connect problems across functions and files, while Pulse, RacerD, cost analysis, custom rules, and build integrations support memory, thread-safety, complexity, and continuous-integration workflows. Binary releases, source builds, Docker images, and a browser example provide several ways to start.

An alternative may fit better when Infer's workflow or scope is limiting. Infer analyzes only files captured during compilation, has no Windows support, and its cost analysis excludes Python, Rust, and Swift. Other products focus on pull-request review, security and dependency governance, broader language coverage, classroom assignments, or copy-paste detection. Compare whether you need IDE or browser access, automated fixes, quality gates, vulnerability and license checks, grading tools, or a different build and CI setup. Pricing also ranges from free plans to paid subscriptions, so match the product's delivery model to your team.
