>- I can't inspect WebSocket frames in anything except Chrome.

For what it's worth, WebSockets show up as type 'Other' in the inspector, and the frames are listed under 'Preview'.

Edit: Safari.

It just says "WebSocket Connection Established", and then a list of "Binary Frame". Is there a way to inspect their contents? Just seeing that frames are being sent doesn't seem very useful for debugging.

I just tested Safari 12.0.3 on macOS 10.14.3 with https://websocket.org/echo.html and it works for me. In the inspector it has a Sockets folder with the socket, and when I select it, it shows the textual content of each frame.

Edit: This is of course textual frames. I don't know where to find a site that demonstrates binary frames. I do notice that if I right-click the textual frame it has "Log Frame Text" as an option; maybe with a binary frame you can ask it to log the binary frame contents?

Edit 2: Ok I found a binary websocket test and unfortunately there is no option to log the binary info. That sucks. I recommend filing a bug report at bugreport.apple.com requesting better tooling around this. It's also worth checking the Safari Technical Preview to see if they've already added any better tooling.

In which browser?
