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 read the Setup guide for a step-by-step guide to set up your own local development server.
