It supports languages and formats including Java, Kotlin, JavaScript, Python, SQL, YAML and Markdown, and provides integrations for Gradle and Maven, with an external SBT integration also linked. Formatter options listed by the project include Google Java Format, ktlint, Prettier, ESLint, Black and ScalaFmt. Spotless links to VS Code and IntelliJ integrations, and offers changed-lines formatting, ignore-file support and a library API.

Some capabilities, including ratcheting and fast incremental formatting, are unavailable in SBT. Spotless is open source under Apache-2.0 and is available for Linux, macOS and Windows.
