:key: Javascript Password Vault - Multi-Platform Desktop Application

Cross-platform, free and open-source password manager based on NodeJS.

Under Development

Buttercup is currently under heavy development, and updates will be pushed here very frequently. The application is currently in alpha, and should be considered unstable.

Please check buttercup-core for more information on Buttercup’s core module.

Download & Install

Head over to our website, or checkout the releases page to download different builds and versions.

If you're using macOS, you can also use Homebrew Cask to download and install Buttercup:

$ brew cask install buttercup

Buttercup is available for macOS (dmg), Windows (exe) and Linux (deb, rpm, tarball) (64bit only). Buttercup is also available for Arch linux (32/64bit) (AUR).

Encryption & Format

Buttercup uses a delta-system to manage archive changes and save conflicts. The archive, upon saving, is encrypted with AES 256bit CBC mode with a SHA256 HMAC. Encryption is performed once the password has been salted and prepared with PBKDF2 at between 200-250k iterations.

Because security with password storage is of the utmost importance, Buttercup will remain in alpha/beta release mode until some level of professional scrutiny has occurred. It is completely possible that security-related changes will occur, but this is inevitable and we handle every question and criticism with great care when it comes to the safety of using our software.

Features

Buttercup supports loading and saving credentials archives both locally and remotely. Remote archives can be stored in a variety of service providers like Dropbox, ownCloud and Nextcloud (and others that support WebDAV, such as Yandex).

Archives store groups and entries in a simple hierarchy. Both groups and entries can be moved into other groups. Deleted items are trashed before being removed permanently.

Buttercup has basic merge conflict resolution when 2 changes are made at once on the file (locally or remote).

You can import from other password managers (such as 1Password and KeePass) by opening your archive and choosing Import from the menu.
