Monolinter

Monolinter is a CLI tool for validating consistency across multiple package.json files in a monorepo (or single project). It checks for consistent package versions, duplicate package declarations, fuzzy version usage, and related package version matches. Current stable version is 1.0.5. Release cadence is low; last release was minor. Key differentiator: modular, extensible with custom validation modules, and designed for CI/CD integration. Alternatives like syncpack focus on version sync but monolinter also catches duplicates and related packages.
