BSL is a self-hostable Brawl Stars private server written in Python, currently distributed for client version v57. This release has two matching downloads: an Android client APK and a Python server ZIP. The server runs on your PC or VPS, while the Android client connects to that server instead of the official Supercell servers. It sits in the same family of open-source BSL/BSDS-style servers that Python developers have iterated on version-by-version (v52, v53, v55, and now v57), and like those, it’s explicitly built on top of the BSDS codebase rather than written from scratch.
Because BSL is Python-based, the typical workflow is: extract the server files, install any required packages (crypto and networking libraries vary by version), and start the server with a command like python3 Main.py. A database (commonly MongoDB) is usually needed to store accounts and progress. This makes BSL a good fit for anyone comfortable with a terminal, not a one-tap mobile install.
Like other private servers of this type, BSL requires a patched Brawl Stars client that points its network traffic at your server’s IP instead of Supercell’s official servers. The patched client and the server must be running compatible versions — mismatches are the most common setup issue reported for this style of project.
The two downloads are meant to be used together. The server ZIP is the Python project you extract on a computer or VPS and run with python3 Main.py. The Android APK is the matching v57 client you install on a phone or emulator after the server is running.
If you’re hosting only for yourself, run the server first, then set the client’s redirectHost to the machine where the server is available and adjust redirectPort only if your setup uses a non-default port. If you’re hosting for other players, give them the Android client only after your server is reachable from their network. The APK by itself is not useful without a compatible BSL v57 server, and the server ZIP by itself still needs a patched client to connect.

BSL (Python) is aimed at technical users who want to run and tinker with their own Brawl Stars private server — testing custom configs, hosting for a small community, or learning how these servers work under the hood — rather than casual players looking for a quick mod apk download.
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.
