BroMetal is a WebGPU graphics library that lets developers write shaders as typed TypeScript functions. A build step compiles the TypeScript DSL into WGSL ahead of time, producing small, optimized modules with no shader compiler or scene graph shipped to the browser. The runtime is extremely lightweight (around 7-19 KB gzipped), enabling instant first-frame rendering. It is designed for developers who want full control over their shaders in a modern TypeScript-first workflow.
In the Frameworks & SDKs space, BroMetal takes a focused approach. It focuses on writing and shipping efficient WebGPU shaders without including a shader compiler or scene graph in the browser bundle. BroMetal is an open-source project aimed at web graphics developers. The project is open source (MIT). It runs on the web.
BroMetal first shipped in 2026. Development happens publicly on GitHub with 49 stars and 79 commits in the last 90 days. Key capabilities include Build-time Compilation, TypeScript DSL, and WGSL Output.
