What is Buttercup?
Buttercup uses a delta-system to manage archive changes and save conflicts. The archive, upon saving, is encrypted with AES 256bit to ensure the security of your credentials. Buttercup uses industry standard methods and configuration for encryption to ensure that there are no weaknesses in the locking/unlocking process of your archives. No personal data is collected by Buttercup and no accounts are required.
Can store password archives in Dropbox, ownCloud, Nextcloud and WebDAV for remote use / sharing - your credentials are completely controlled by you and available anywhere that you have internet connection. The desktop application supports offline archives by saving files locally. The mobile application supports in-browser login auto-filling.








Comments and Reviews
I love opensource and free software please add mega sync for vaults like dropbox
phone app isn't stable. crash too much and not fixed for years after many people reported.
A fancy Password Manager with no hardly any features to compete with alternatives like Keepass. Even Worse , they claim to be a "privacy focused app", yet require you to go to the Play Store to install in on Android devices. Inexcusable!
Let me count the reasons this program should be avoided:
Program doesn't install on Linux Mint 19.3 properly and will not operate giving an error about missing a needed update file.
Program will not create a new archive to start using it for passwords.
The website looks like something form the 80's. This is supposed to be a legitimate open source app site?
There is no documentation with it or support outside of going to the creators Twitter page. And what if you don't use Twitter? I have to sign up to find out how to fix your broken software?
Needs better export options and a security audit suite to find duplicate/weak passwords
Best offline free and opensource password manager which looks modern. It has cloud sync via dropbox , nextcloud etc
Buttercup is a pretty well made Password Manager, made with Electron Framework it gives a nice interface to it, pure and clear.
