The development is very active and I hope it will continue.
There are still some things to fix and improve but we can use it daily on several OS.
Kudos to the dev!!!
And yes it's fully open source, awesome!

I pledged for bitwarden on kickstarter, because of the 3 qualities I listed in the title. Out of all the password managers I've tried over the years, this is my favorite.

Awesome. Open source, free, clean UI. Doesn't slow down browser like some other applications. What's not to love?

Finally on Firefox and I can ditch Chrome! :-)

This addon is what I'm planning to transition my entire family onto (from Lastpass) after it adds a few more features. It's finally provided the world with a quality free and open source in-browser password manager. The author seems to be more mindful of security pitfalls of other similar extensions which creates some trust that security will remain a top priority. I'm very excited about this addon's future.

I've been using the chrome version and had to login to Chrome to leave this review since I'm still waiting for the Firefox extension to be approved.

at last a free / open Source password manager, just waiting for the firefox addon to completely replace LastPass

I don't really like the theme, but beggars can't be choosers. Hopefully this comes out of review soon!
