Two people can be equally paranoid about passwords and end up with opposite setups. One runs a server. The other keeps a single file. Both are right — for their own life.
Here's how to figure out which one is yours.
The core difference in one line
Vaultwarden is a little server you run that syncs passwords to every device automatically. KeePass is a single encrypted file you carry around yourself.
That's the whole fight. One trusts a server you control. The other trusts a file you move by hand.
Vaultwarden: the "it just syncs" option
Vaultwarden is a lightweight version of Bitwarden that runs on your own hardware. Install it, and you get browser extensions, phone apps, and autofill — all talking to your box instead of a company's cloud.
Pick this if you:
- Use passwords on 3+ devices daily
- Want autofill that just works in Chrome, Firefox, and your phone
- Share logins with family members
- Are okay running one small container that stays online
The trade-off: your server has to be up and reachable. If it's off, new devices can't sync until it's back. And a server exposed to the internet is a target — so it needs a reverse proxy and HTTPS done right.
KeePass: the "one file, total control" option
KeePass (and forks like KeePassXC) stores everything in a single .kdbx file. That file is fully encrypted. Nothing runs. Nothing listens. Nothing can be attacked over the network — because there's no network.
Pick this if you:
- Want zero moving parts
- Are fine copying a file to your phone or a USB stick
- Distrust anything that stays online
- Mostly log in from one or two devices
The trade-off: syncing is manual. Many people drop the .kdbx file into Syncthing or Nextcloud to auto-sync it — which quietly rebuilds the convenience of Vaultwarden with more steps.
The honest comparison
| Vaultwarden | KeePass | |
|---|---|---|
| Setup effort | Medium | Very low |
| Auto-sync | Built in | You wire it up |
| Attack surface | A live server | Just a file |
| Family sharing | Easy | Awkward |
| Works offline | Needs server up | Always |
Which should a beginner actually pick?
If you're nervous and just want your passwords out of Chrome, start with KeePassXC. Make one file. Set a strong master password. Done in ten minutes. No server, no exposure, no ports.
When you get tired of copying the file around, then graduate to Vaultwarden. You'll appreciate what it solves because you'll have felt the pain first.
Your one action today
Install KeePassXC on your laptop. Create a vault. Move your five most important passwords into it — email, bank, and your main shopping accounts. Then delete those same passwords from your browser. That single step gets your most valuable logins out of the least safe place they live.
