Comparisons of these two usually argue about encryption. Both encrypt the vault properly, and that is the least interesting thing about the choice.
The real question is where the vault lives, and therefore who is responsible when something goes wrong.
Two different responsibility models
KeePass is a database file. It sits on your disk. You decide how it is backed up, how it reaches your phone, and what happens if the drive dies. No company is involved and no company can help you.
Bitwarden is a service. Your encrypted vault sits on their infrastructure and syncs to your devices. They cannot read it, and they can restore it, keep it available, and support you when something goes wrong.
Both are sound. They hand you a different job.
The local model looks like this: the thing is in your house, among everything else in your house, and its safety is a habit rather than a service. That is genuinely stronger in one direction and entirely dependent on you in another.
What a local file removes, and what it removes with it
Removes: any possibility of a service breach exposing your vault, any dependence on a company's continued existence, any policy change made without you, any subscription.
Removes with it: the safety net. If you delete the file, nobody has a copy. There is no reset, no support desk, no restore.
That is not a flaw. It is the same property described from the other side, and it is the part people skip when they choose the local option for its purity and then keep it in exactly one place.
What a hosted service adds, and what it costs
Adds: sync that works, recovery paths, a team that notices problems, and someone whose job is availability.
Costs: a dependency. On a company continuing to exist, keeping its policies, and not being acquired by someone with different priorities. Bitwarden stores an encrypted blob it cannot read, so a storage breach does not hand over passwords, and it remains a party in your arrangement.
The hosted model looks like this: identical units in a building somebody else keeps the lights on in. The operator cannot open yours, and the operator is still the reason the corridor is lit and the door is standing.
Self-hosting moves the problem, it does not remove it
Running Bitwarden on your own server removes the dependence on someone else's service and replaces it with dependence on your own server, your own updates and your own backups.
For someone who already runs infrastructure, that is a fair trade. For someone who does not, it moves the responsibility toward the party with the least time to spend on it, which is usually the worst place for it to sit.
How to actually decide
Ask which failure you are more likely to survive.
If you have a backup habit that genuinely runs, and you prefer no third party in the arrangement, KeePass fits and it fits well.
If the honest answer is that your backup habit is aspirational, a hosted service is doing real work for you, and pretending otherwise costs more than the subscription.
The worst outcome is the middle: choosing the local file for its independence, then storing it in one place and never testing a restore. That combines the responsibility of one model with the safety net of neither.
What neither of them fixes
A weak master password. Both models collapse to the same failure, and no storage decision compensates for it.
Phishing. Both will happily autofill into a convincing fake page if the address matches closely enough for you to be fooled, because you are the one who decided the page was real.
And the account that recovers everything else. If your email can reset the things your vault protects, then your mailbox outranks this entire comparison, whichever side of it you land on.

What is the real difference between KeePass and Bitwarden?
Where the vault lives and who is responsible for it. KeePass is a database file on your own machine, and you decide how it is backed up and synchronised. Bitwarden is a hosted service that stores your encrypted vault and syncs it across your devices. Both encrypt the vault so the storage location cannot read it. The difference is not encryption, it is who carries the responsibility when something goes wrong.
Is KeePass more secure than Bitwarden?
Not inherently, and framing it that way hides the actual trade. A local file has no service to breach, which removes one class of risk entirely. It also has no service to restore it when you delete it, and no team watching for problems. Bitwarden stores an encrypted blob it cannot read, so a breach of their storage does not hand over your passwords, but it does mean depending on a company. You are choosing which risk you would rather manage, not more or less security.
What happens if I lose my KeePass file?
It is gone, and nobody can help you. There is no reset, no support desk, no copy on someone else's server. That is the direct consequence of the model working as intended: nobody else has your data, which also means nobody else has a copy. Anyone using KeePass without a tested backup routine has quietly chosen the risk without noticing they chose it.
Can I self-host Bitwarden?
Yes, and it is worth understanding what that changes. Self-hosting removes the dependence on someone else's service and replaces it with dependence on your own server, your own updates and your own backups. It moves the responsibility rather than removing it, and for most people it moves it toward the party with less time to spend on it. That is a reasonable choice for someone who already runs infrastructure and a poor one for someone who does not.
Which should I choose?
Ask which failure you are more likely to survive. If you have a reliable backup habit and prefer nothing to depend on a third party, KeePass fits. If the honest answer is that your backup habit is aspirational, a hosted service is doing real work for you and Bitwarden fits. The worst outcome is choosing the local file for its purity and then keeping it in exactly one place.
