Our verdict on detekt
detekt is an open-source static code analysis tool for Kotlin projects. It checks code for smells, style issues, complexity, potential bugs, performance concerns, and other maintainability problems. Kotlin teams can run it from the command line or through Gradle, with support for Android, JVM, JavaScript, Native, and Multiplatform projects. Its strongest fit is a Kotlin codebase already using Gradle or IntelliJ IDEA and looking to add configurable analysis to development and build workflows.
The published offering is open source and includes a free plan, with no tiered paid plan structure described. That makes detekt suitable for teams that want to add linting without a subscription commitment. Its ecosystem fit is a major strength: integrations include Gradle, Maven, Bazel, IntelliJ IDEA, and GitHub Code Scanning. Reports can be exported as HTML, Markdown, SARIF, XML, or custom formats, which supports local review, build automation, and code-scanning workflows. Windows, macOS, and Linux are supported.
Configuration and extensibility give detekt depth beyond a fixed ruleset. Teams can define YAML configuration, customize rules, create baselines for existing findings, suppress selected issues, and add custom rule sets or plugins. Complexity reports and automatic fixes add further workflow support, while the IntelliJ IDEA plugin provides warning highlighting during development. The main trade-off is its narrow language focus: teams maintaining several programming languages will not get one shared linter from detekt. Choose it for Kotlin-centered projects that value configurable analysis and build or IDE integration; choose another tool when broad multi-language coverage is the primary requirement.
