What is Buttercup?

Buttercup is a lightweight password manager for desktop and mobile. It comes with a strong 256bit AES encrypted vault that keeps your passwords and credentials secure and safe.

Buttercup is a completely free, open-source solution which means you can download and use it without worrying about lock-in or fees.

The project is consistent with several open-source child projects that include desktop, mobile, and Buttercup Core repositories.

Buttercup organizes all of your passwords, and key entries in collections or groups, which are organized under different accounts.

The mobile app uses React Native, while the desktop app uses React and Electron.
