Could you build this?
Partial Compiling an existing terminal emulator core to WebAssembly is feasible, but adapting Ghostty's custom Zig architecture and GPU-accelerated rendering to WebGL/WebGPU in the browser requires deep graphics and systems expertise.
What it would actually take: The architecture relies on compiling Ghostty's native Zig codebase to WebAssembly/WASI, connecting POSIX terminal emulation to a browser-compatible backend, and binding rendering calls to WebGPU/WebGL or Canvas. The hard part is reconciling native platform assumptions (multi-threading, font shaping via HarfBuzz, POSIX PTYs, and OS-level windowing/input pipelines) within the constraints of the browser sandbox. This requires specialized knowledge of Zig, WebAssembly compilation toolchains, and low-level terminal rendering protocols.
