Configure your build

Pick the modules you actually need. The configurator generates a bun build --compile command and estimates the resulting binary size. Defaults to everything checked — uncheck what you don't need.

Preview. The UI works today; the --with / --without build flags it emits ship in a follow-up Parabun release. Use this page now to plan the modules your app will need; the command will work as soon as the runtime flags land.

        Notes: sizes are debug-build estimates; release builds are roughly 40% smaller after stripping.
        bun:gpu uses system Metal / CUDA via FFI and adds no static-link weight; same for
        bun:camera (V4L2 / AVFoundation / Media Foundation are all OS-provided).
        bun:llm piggybacks on bun:gpu+bun:simd so it's free if you've already
        included those.
      


      

        Scope. The added modules target typed-array numeric work, embarrassingly-parallel loops, and
        GPU-friendly matrix shapes. HTTP handlers, JSON parsing, and ordinary application code go through the same paths
        as upstream Bun — no changes in performance or behavior are expected there.
