KeePass Web is a password manager for people who don't want to trust a company with their secrets.

It ships as a single, self-contained HTML file. There is no install, no server, no framework, no third-party library handling your credentials. The source code is short enough to read in a sitting. The only browser feature it requires is WebCrypto, which every modern browser supports. What you see is exactly what runs.

The free version works entirely locally: open the file, drag in your KDBX database, use it. Nothing leaves your machine. GitHub Sponsors unlock https://keepass.online, which lets you open your KDBX directly from your own Google Drive, Dropbox, or OneDrive — from any browser, anywhere — without your database or master password ever touching our servers.

Sponsorship funds two things: active maintenance so the project doesn't become another abandoned KeePass client, and a security bounty program so independent researchers have a financial reason to find problems before anyone else does.

If you want a password manager you can actually verify, this is it.
