What each one is

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

Prettier

Leader

An automatic formatting tool that parses code and reformats it according to opinionated style rules, adjusting wrapping based on line length constraints.

Independently observed

Trunk

Trunk automatically detects and isolates unreliable tests that block deployments, while managing a merge queue system that coordinates related changes to run in parallel. This reduces infrastructure costs and accelerates software delivery by preventing test flakes from delaying code merges.
