Changed. aihawk ui downloads the engine before it opens the port, on one terminal line that follows the download: a percentage and the megabytes, then verifying, extracting, ready. Until now it printed browser ready with nothing on disk, and the engine arrived inside the first message. The floor on invisible-playwright-mcp moves to 0.13.0, where the server fetches the engine as it starts.
Withdrawn in 0.8.0, the same weekend: both ways in now start with pip install aihawk followed by invisible-playwright fetch, in the terminal you are already in, and neither the server nor this interface fetches on its own.
