# Running the CTS on Deno
Since version 1.8, Deno experimentally implements the WebGPU API out of the box.
You can use the `./tools/deno` script to run the CTS in Deno. To do this you
will first need to install Deno: [stable](
https://deno.land#installation), or
build the main branch from source
(`cargo install --git
https://github.com/denoland/deno --bin deno`).
On macOS and recent Linux, you can just run `./tools/run_deno` as is. On Windows and
older Linux releases you will need to run
`deno run --unstable --allow-read --allow-write --allow-env ./tools/deno`.
