detekt is a static code analysis tool for the Kotlin programming language that detects code smells and enforces configurable rule sets. It ships as a CLI, a first-party Gradle plugin, and an extensible rule engine with report output in HTML, Markdown, SARIF, and Checkstyle XML.

Use cases

• lint kotlin code in a gradle project
• find code smells in my kotlin codebase
• enforce code quality rules in ci for kotlin
• generate a baseline of existing issues for a legacy kotlin project
• write custom static analysis rules for kotlin
• produce sarif reports for code scanning
• measure cyclomatic complexity of kotlin code

When to choose

• you have a Kotlin JVM, Android, Multiplatform, JS, or Native project and want automated code quality checks
• you need configurable lint rules with baselines and suppression support
• you want CI-friendly reports in SARIF, HTML, Markdown, or Checkstyle formats

When to avoid

• your codebase is not Kotlin (use language-specific linters like ESLint, Pylint, or Clippy)
• you need full type-aware IDE inspections only - IntelliJ's built-in inspections may suffice
• you need runtime bug detection or dynamic analysis rather than static analysis
