User reviews

Buttercup is praised as an open-source, free, and practical password manager with good desktop and mobile support, serving as a solid alternative to others like LastPass. However, many users report that the Chrome extension becomes unstable or stops working after updates, especially due to new requirements of pairing with the desktop app. This shift harms usability, complicates vault importing, and disrupts password autofill convenience. Users also note CPU performance issues and UI glitches caused by the extension. While the core app is appreciated, the browser extension experiences recurrent problems impacting user satisfaction.
Pros
  • Open source and cross-platform password manager.
  • Free and practical to use.
  • Provides control over password security and storage.
  • Good desktop and mobile apps available.
  • Useful alternative to other password managers like LastPass.
Cons
  • The Chrome extension often fails or stops working after updates.
  • Recent versions require linking with the desktop app, causing usability issues.
  • User experience with the extension and desktop app connection is cumbersome.
  • Issues with importing old vault files and connecting to cloud storage after updates.
  • Extension causes high CPU usage and UI/UX inconsistencies on websites.
