About Kotlin Static Analysis Tool

Kotlin Static Analysis Tool is part of APKLint’s code quality toolkit — Static analysis for Kotlin, Java, and your Gradle build. It’s free to use and needs no account.
Your privacy is the default: what you submit is processed on our servers over an encrypted connection for that request only — it isn’t written to file or object storage, and never shared.
What Kotlin Static Analysis Tool checks
- Kotlin code smells and risky patterns
- Nullability (!! and lateinit), coroutine scope (GlobalScope, runBlocking), and lifecycle (observeForever)
- Common style issues
- Fast feedback on a pasted snippet
Good to know: A heuristic Kotlin check — not detekt or ktlint. For enforced rules, wire detekt/ktlint into your build.
When to use Kotlin Static Analysis Tool
- Best for
- Kotlin-specific code smells and risky patterns, nullability, coroutines, and lifecycle pitfalls, via fast static checks.
- Not the right tool for
- Not for Java code (use Android Lint or the Code Checker) and not full project lint.
- What you get back
- Kotlin-focused findings: null-safety, coroutine/scope misuse, and idiomatic smells.
- How it differs from related APKLint tools
- It is the Kotlin-only counterpart to Android Lint and the general Code Checker, with rules aimed at Kotlin idioms.
- Limitations
- Pattern-based and snippet-scoped; deeper Kotlin issues need a full compile.
