detekt vs ESLint

detekt is a free static code analyzer for Kotlin that helps identify code smells. It supports Android, JVM, JS, Native, and Multiplatform projects, and runs on Linux, macOS, and Windows. Developers can configure rule sets, create baselines for existing issues, and suppress findings with @Suppress annotations. Reports can be generated as HTML, Markdown, SARIF, Checkstyle XML, or custom formats; complexity reports can include lines of code, cyclomatic complexity, and code smell counts. The project provides a Gradle plugin and documents use with Gradle, Maven, and Bazel builds. Its Gradle plugin requires Gradle 6.8.3 or higher. Custom rule sets can be added through detekt's RuleSetProvider and ServiceLoader pattern, and the marketplace lists community rules, extensions, and plugins. CLI installation guidance covers Homebrew on macOS, Scoop on Windows, SDKMAN on Unix-like systems, and NixOS. detekt supports autofix, IDE use, and CI. Its security policy says patches are applied up to the current minor version, with earlier versions handled case by case.
