Overview
KeeWeb was created in 2015 by Antelle, a Netherlands-based developer, as an open-source password manager fully compatible with the KeePass .kdbx file format. It is released under the MIT license and has continued as a community-maintained hobby project.
It ships as desktop apps for Windows, macOS and Linux, and as a browser-based web app distributed as a single self-contained HTML file, making it easy to self-host anywhere.
Key Features
KeeWeb reads and writes standard .kdbx database files encrypted with AES-256 or ChaCha20-Poly1305, with all encryption and decryption happening locally on the user's device.
It integrates with Dropbox, Google Drive, OneDrive and WebDAV for syncing, supports opening and searching across multiple database files at once, and includes a password generator, auto-type, and customizable themes.
Pricing
KeeWeb is entirely free and open source with no subscription tiers, premium features, or paid add-ons of any kind.
The only ongoing cost is whatever cloud storage or hosting a user chooses to sync or host their .kdbx database file, since KeeWeb itself has no backend service to pay for.
