What each one is

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

ESLint

Leader

Open-source linter that uses abstract syntax tree analysis to detect JavaScript code issues and apply syntax-aware fixes, with extensive customization through custom rules and parsers.

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.
