Infer review
A focused, self-hosted analyzer for memory safety, concurrency, taint, and code issues.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Infer is an open-source static program analyzer for teams maintaining Java, C, C++, Objective-C, or Erlang code. It examines source code for null dereferences, memory-safety problems, data races, thread-safety issues, taint flows, resource leaks, and other coding issues. The product fits engineering groups that want to run analysis within their own development and CI environments, particularly when memory safety and security-related findings are priorities.
Infer has a straightforward pricing profile: the product is open source and includes a free plan. Its documented distribution options include binary releases, source builds, and Docker images, while supported platforms are Linux, macOS, and self-hosted deployment. That makes it suitable for teams comfortable managing their own analysis environment rather than looking for a hosted service with tiered operational support. The published workflow focuses on local builds, command-line analysis, incremental or differential runs, and CI checks that can analyze changed files and gate issues.
The standout strength is breadth within its supported analysis model. Teams can combine null and memory-safety detection with race, taint, resource-leak, and coding-issue checks, then extend the analyzer through custom checkers and an abstract-interpretation framework. This makes Infer more adaptable than a narrow memory checker, while its five-language scope remains a meaningful boundary. Choose it when open-source licensing, self-hosting, CI analysis, and custom analysis matter. Consider another tool if your codebase falls outside the listed languages or your team prefers a managed, broader-platform experience.
