The short answer
Yes. Rebuilt or re-downloaded automatically when needed.
What is it?
Cypress, the end-to-end testing tool, stores its desktop app binary in ~/Library/Caches/Cypress, one folder per version installed by your projects. Upgrading Cypress across projects leaves older binaries behind, each typically a few hundred MB.
What happens if you delete it?
When a project needs a version that is no longer cached, Cypress downloads it again during npm install or npx cypress install. Your tests and settings live in your projects and are not affected.
How to remove it properly
Run npx cypress cache prune, which deletes every cached Cypress version except the one the current project uses. npx cypress cache list shows what is cached and npx cypress cache clear removes everything. These commands delete permanently, without the Trash.
Use the tool’s official command: cypress cache prune
How MoreRoom helps
MoreRoom recognises this item, shows its real size and when it was last used, and labels it “Safe to remove”. In the free version you can move it to the Trash in one click, with Undo; Pro collects every safe item at once.
When the tool is installed, MoreRoom runs its official command for you (cypress cache prune) instead of deleting files — and tells you that this step can’t be undone.
