What does this offer over other local-first password managers? For example, there are a fair few Android/iOS apps based on KeePass (I currently use https://www.keepassdx.com on my Android phone).
It would be good to see screenshots of Bramble. The "sprawl of plugins and forks" in KeePass is why I use it. Many of the KeePass clients have modern UI's. I'll think about switching to Bramble when the sprawl begins.
Keepass also can't match URLs with Regex which is something I make use of in bitwarden.
