What each one is

The product in its own terms, so the numbers below have context.

RuboCop

Leader

RuboCop is an open-source Ruby linter and formatter that enforces code style based on the Ruby community style guide. It detects code quality issues and can automatically fix many of them, with extensive configuration options and extensibility through community plugins.

Independently observed

Trunk

A platform that identifies unstable tests, automatically isolates them from blocking merges, and provides intelligent merge queue management to reduce build delays and developer friction.
