A CLI tool that cleans up yarn.lock files by removing duplicated package resolutions in Yarn v1 projects. It merges duplicate dependency entries when a single version satisfies overlapping version ranges.

Use cases

• deduplicate packages in yarn.lock
• reduce duplicate dependencies in a yarn v1 project
• clean up lockfile before committing
• shrink node_modules by merging duplicate package versions
• gradually deduplicate specific packages in yarn.lock

When to choose

• you use Yarn v1 and your yarn.lock has duplicated package versions
• you want to reduce install size and dependency tree conflicts
• you want a quick npx-runnable tool with no install

When to avoid

• you use Yarn v2+ (Berry), which deduplicates natively
• you use npm or pnpm instead of Yarn
• you need non-overlapping version ranges to be merged (impossible by design)
