Checks	It provides its own checks and can also run Clang Static Analyzer checks.	Built-in checks cover consistency, design, readability, refactoring, and warnings, and low-priority checks can be included with strict analysis.
Configuration	Checks can be selected with comma-separated positive and negative globs, and configuration can be read from a .clang-tidy file.	Credo uses a `.credo.exs` configuration file that can be placed in the project root or its `config/` folder.
Custom checks	The tool provides an interface for writing custom checks, which can use preprocessor callbacks or AST matchers and attach fix-it hints to diagnostics.	Users can add project or domain specific checks by implementing the `Credo.Check` behavior and configuring the check.
License	The LLVM project states that its code is licensed under the Apache 2.0 License with LLVM exceptions.	Credo is released under the MIT License.
Purpose	clang-tidy is a Clang-based C++ linter for diagnosing and fixing typical programming errors, including style violations, interface misuse, and bugs detectable by static analysis.	Credo is a static code analysis tool for Elixir focused on code consistency and teaching.
