Brawl Draft is a free draft assistant for Brawl Stars Ranked. You set the map, tap the bans and picks as they happen, and it ranks what to take next using real ranked match data and a trained win-probability model.
It is an independent, unofficial fan project. It is not affiliated with, endorsed by, or sponsored by Supercell.
Brawl Draft is built and maintained by Mitchell Tatge, an independent developer working on it alone. There is no company behind it and no account to sign up for.
The whole project is open source under the MIT license (the data pipeline, the model, the draft engine and this site) at github.com/mctatge/Brawlstars-Draft-Tool. If you want to check how a number was produced, the code that produced it is public.
Most draft tools stop at a win rate, a synergy number and a counter number. Brawl Draft started as an attempt to do the whole thing properly: collect real ranked matches at scale, train a model that reads an unfinished draft natively, fuse it with empirical map statistics, and then show every component of every score so you can judge the advice rather than take it on faith.
It was built to be both a practical tool for ranked drafting and an end-to-end machine-learning project: data pipeline, trained model, product. It is only useful while the data keeps flowing, so the collector runs continuously and the model is retrained as the meta moves.
Every number traces back to real ranked matches collected through the official Brawl Stars API, deduplicated so each match counts once. The current model was trained on more than a million of them, with a held-out set that was never shown to it during training.
Brawler and map reference data and images come from Brawlify / BrawlAPI. How it works is the plain-English walkthrough of the pipeline and the model's real accuracy; the model dossier has the architecture, the equations and the held-out numbers.
It cannot see how well anyone plays. Ranked outcomes are mostly decided by aim, positioning and rotations, none of which a draft can see, so the model's edge over a coin flip is real but modest. It is used to rank picks relative to each other, not to predict your game. The FAQ goes into the limits in more detail.
