KeeWeb

KeeWeb is a cross-platform password manager that opens existing KeePass kdbx database files or creates new vaults for your credentials. It reads kdbx files made by other applications such as KeePass and KeePassXC, so you are not locked into a single client. You can run it as a desktop app on Linux, Windows, or macOS, or directly in your web browser.

You decide where your credential vault lives. KeeWeb saves the database as a local file or syncs it to cloud services including Dropbox, Google Drive, and Microsoft OneDrive. The web build is a single HTML file with an optional service worker for offline access. Because it speaks the kdbx format directly, your data stays portable between KeeWeb, KeePass, and KeePassXC.

KeeWeb is free and open source. You can self-host it on your own server, since everything needed to run the app ships as a single HTML file. Pre-built Docker images cover containerized setups, and the app can sit behind a reverse proxy such as Traefik.
