Bitwarden is an open source password manager

The source code for Bitwarden is hosted on GitHub and everyone is free to review, audit, and contribute to the Bitwarden codebase.

We believe that being open source is one of the most important features of Bitwarden. Source code transparency is an absolute requirement for security solutions like Bitwarden.
