KeeWeb is a free and open-source password manager compatible with KeePass, available as a web version and desktop apps.

[2] KeeWeb is written in JavaScript and uses WebCrypto and WebAssembly to process password files in the browser, without uploading them to a server.

[3] KeeWeb is also available as an Electron bundle which resembles a desktop app.

The desktop version adds some features not available on web:[4] KeeWeb can also be deployed as a standalone server, or installed as a Nextcloud app.

[5] KeeWeb was praised by Ghacks Technology News in 2016 as "brand-new" fixing the "shortcoming of a web-based version" of KeePass, and by Tech Advisor in 2020 as "well-designed cross-platform password manager".
