Bash Fighter is a free and open-source, browser-based platform fighter that supports up to 20 players in a single match. It is played directly in a web browser at bashfighter.com, with no download, plugin, or account required.
The game is built with a custom deterministic, fixed-tick simulation core written in TypeScript, paired with a PixiJS renderer for presentation. It supports online multiplayer netplay, multiple stages, and several match modes (including a Stocks mode and a timed Brawl mode), and is under active development.
Source code is hosted publicly on GitHub at github.com/BashEntertainment/bash-fighter, and the project is released under the AGPLv3 license, with an accompanying Contributor License Agreement for outside contributions. As of September 2026, the project is early / pre-1.0 and actively soliciting outside contributions via GitHub issues and Discussions.
