buttercup-core VS Passbolt

https://github.com/buttercup/buttercup-desktop https://buttercup.pw/

One thing to do, especially if it is your first contribution to open source, is to find some projects. In my opinion, it is great to choose some technologies and software you use every day. An example for me is my password manager, Buttercup (buttercup.pw). I love to contribute to it because it is helpful for the community. Moreover, it is a satisfaction to see and use my updates in the product. So, the first thing to do is to list some projects you like, for example:

I feel like Buttercup [1] doesn't get enough attention. Open source, available on all platforms, and has imports from multiple other password managers. If several people offered a small monthly donation for some time, we'd all be in a more competitive situation with password manager companies whose interests drift from our own through time.

ButterCup

I’m the creator of https://buttercup.pw - it should work on LAN only. If it doesn’t that’s something I’d definitely add support for.

Buttercup looks pretty good, and it had android and iOS apps https://buttercup.pw

The easiest are LastPass and [Buttercup](https://buttercup.pw/)

http://buttercup.pw is free, runs on all major platforms, and is really nice to use.

Passbolt - Open Source Alternative to 1Password

Here's another to add to the list, Passbolt. It is open source and basically built for teams and enterprise. It is design primarily with a unique security model which is based on asymmetric end-to-end encryption, with user-owned encryption keys and support easy cross functional team collaboration. Can it hosted on-prem or host it in cloud depending on your preference. Might be too much information and a tad bias as I work here but wanted you to have all the information as passbolt fits your requirement for business level password manager.

Fyi there is also Passbolt.

I currently switched from keepass to passbolt: https://www.passbolt.com/

I might be bias here as I work here but another recommendation would be passbolt. Open source password manager that is built for teams and businesses. You can either self-host or host it in the cloud, really depending on what you require and supports secure granular sharing of credentials with nested permission in just a few clicks. Its a solution that is built with security as a top priority. It supports asymmetric end-to-end encryption based on OpenPGP cryptography using both public-private key for encryption/decryption. No secret key is stored on the server side. Both the free community edition and the paid pro version are 100% open source.

All that said...here's my shameless plug: I work for passbolt. You mentioned you have a small team, you might give it a look: https://www.passbolt.com/ there's a community edition you can install for free on the server of your choice. I'm here and happy to answer any questions.
