BSL (C#) is a self-hosted Brawl Stars private server written in C#, aimed at players who want to run and fully control a server for a recent version of the game — currently version v59. It’s part of the same BSL naming lineage as the Python builds, but rewritten in C#, which typically means it runs as a compiled .NET application instead of a Python script.
Being written in C# and hosted by you, BSL (C#) gives the operator direct control over the server: match logic, accounts, progression, and configuration all live on infrastructure you run, rather than on Supercell’s official servers. This is the core appeal of any private server in this family — nothing is hidden behind a closed backend.
As a C#/.NET project, BSL (C#) generally needs a .NET runtime installed on the host machine, plus a database for player data. You build or run the compiled server, point a compatible patched Brawl Stars client at your server’s address, and the client connects the same way it would to an official server — just talking to your machine instead. This is not an APK you tap and play; it’s server software meant for a PC, VPS, or home server.

| Requirements | .NET runtime, a database, a matching patched client |
BSL (C#) suits developers, server admins, and hobbyists who want a recent-version Brawl Stars private server they can configure, extend, or host for a small community — a step up in complexity from downloading a pre-built mod, but with far more flexibility.
Self-hosting means you’re responsible for the server: where you source the project files from, how you secure the host, and what data you store. Only run server software from a source you trust, and never point a patched client that’s logged into your real Supercell account at any private server.
