is there a selfhosted password manager service that works offline? eg. I can save or edit passwords in the client (app/browser extension) and it will be synced once the password manager service is reachable again?
I had assumed bitwarden/vaultwarden would work like that, but it doesn't.
I don't want the system to be hosted online, only in my local Lan.

update, because this is still being boosted: please read my post on this at https://www.splitbrain.org/blog/2025-08/17-password_manager_woes

@splitbrain Interesting, I've been using Vaultwarden for years now and after all the testing *hum* outage *hum* everything seems to work fine offline

As in, even if the server is in valhala, I keep my cache in the browser/iOS app and I can still work out my passwords

I'm curious about your experience

@docyeet yes. you can access your passwords. But you can not create new ones when your vaultwarden server is not accessible. There is no create now, sync later.
@splitbrain @docyeet This blows my mind, I’ve been using keepass since forever and thought about trying vaultwarden.
Would a combination with syncthing fit the bill? The latter also works through NAT etc, but could also be configured to only sync locally. Then you would simply not get synced when outside of your lan.
@splitbrain @docyeet I have this setup. When i am not a home i have a vpn tunnel open to my homenetwork, so i can access my selfhosted vaultwarden anytime. VPN is connecting to my fritzbox.
