Final Verdict

Can I migrate from KeeWeb/KeePass to Vaultwarden?

Which is more secure?

Can I use both?

Related Vaultwarden is the better choice for most people. It has browser auto-fill, native mobile apps, password sharing, and a polished experience across every platform. KeeWeb is better if you're already using KeePass databases, want a file-based vault with no server-side database, or prefer the simplicity of a single encrypted file you can move anywhere. Vaultwarden is a server-side application that stores encrypted vaults in a database (SQLite) and syncs across all Bitwarden clients. It runs as a persistent service that clients connect to. KeeWeb is a web-based UI for KeePass (.kdbx) files. It serves static files and all encryption happens client-side in the browser. Your vault is a single encrypted file — no database, no server-side state. These are fundamentally different architectures serving different philosophies. Vaultwarden requires a running server, HTTPS (Bitwarden clients require it), and a reverse proxy. Setup is straightforward but involves more moving parts. KeeWeb is a static web app served by nginx. Deploy the container and you're done. Creating and managing the .kdbx file is a separate step — you can create one with KeePassXC or within KeeWeb itself. Winner: KeeWeb for pure simplicity. But Vaultwarden's setup is still easy and the result is more feature-complete. Both are extremely lightweight. KeeWeb is slightly lighter because the server does almost nothing — all the work (encryption, decryption, search) happens in your browser. Important note: KeeWeb development has slowed significantly. The last major release was in 2022. It's functional and stable, but don't expect new features. The KeePass ecosystem overall is very mature and stable. Vaultwarden benefits from the entire Bitwarden client ecosystem, which is actively developed with frequent updates. Vaultwarden is the better password manager for daily use. Auto-fill, mobile apps, syncing, sharing — it handles everything a modern password manager should. KeeWeb is the better choice for KeePass users who want web access to their existing .kdbx vaults without changing their workflow. It's also the right choice if you value the simplicity and portability of a file-based vault — one encrypted file, no server dependency, works with any KeePass client on any platform. If you're choosing your first self-hosted password manager, choose Vaultwarden. If you already live in the KeePass ecosystem, KeeWeb adds web access without disrupting anything. Yes. Export your .kdbx file to CSV from KeePassXC, then import the CSV into Vaultwarden's web vault under Tools → Import Data → KeePass 2 (csv). Both are secure. KeePass's .kdbx encryption (AES-256/ChaCha20 with Argon2) is well-audited and battle-tested. Vaultwarden uses Bitwarden's AES-256 with Argon2. The key difference: KeeWeb does zero server-side processing (pure client-side), while Vaultwarden processes API requests on the server (but doesn't decrypt vault data server-side). Both approaches are sound. Not for the same vault — they use different formats. But you can run both and keep separate vaults. Some users run Vaultwarden for daily auto-fill and keep a KeePass backup vault.
