The Bitwarden Server project contains the APIs, database, and other core infrastructure items needed for the "backend" of all bitwarden client applications.

The server project is written in C# using .NET Core with ASP.NET Core. The database is written in T-SQL/SQL Server. The codebase can be developed, built, run, and deployed cross-platform on Windows, macOS, and Linux distributions.

Please refer to the Server Setup Guide in the Contributing Documentation for build instructions, recommended tooling, code style tips, and lots of other great information to get you started.

You can deploy Bitwarden using Docker containers on Windows, macOS, and Linux distributions. Use the provided PowerShell and Bash scripts to get started quickly. Find all of the Bitwarden images on Docker Hub.
