Buttercup is free to download and use and is available for Windows, Mac and Linux. Use it alongside the browser extension and mobile app for a completely portable experience.

What's New

The foundational packages that make up the desktop application have been upgraded to the newest stable versions. Importers for 1Password and Bitwarden have been updated to include various bugfixes and stability improvements.

It is now possible to migrate your vaults to the "Format B" style that uses a fundamentally different structure to store your data. It's more resilient and much more efficient, which should result in faster unlock times, smaller vaults and less risk of conflicts/data-loss. It is a beta feature and is recommended only if you have backups of your vault (in the stable format) and are willing to take the risk.

Google Drive functionality has been updated to mitigate short authentication periods and broken re-authorisation processes.

  • New vault settings dialog, including backup options for individual vaults. Currently supports automatic backing up of saved vaults locally.
