github

Requires creating a GitHub App with specific permissions and configuring multiple environment variables, which can be time-consuming and error-prone, as detailed in the 'Using your own GitHub App' section.

Designed only for CI, so developers miss inline feedback when running ESLint locally, potentially delaying issue detection until pull request creation, as emphasized by its CI-only execution.
