Not 100% sure if this is the right place to post this.

I made a tool that extracts the inputs from replays and shows them on a web page.
https://replaystats.appspot.com/

How it works:

• You select the exchange version, where the replay is hosted (TMNF, United and TM2 for now)
  
• You enter the ID of the replay (last number in the MX-Download link)
  
• The server downloads the replay and extracts the inputs using the tools provided by donadigo
  

I put some more information on Reddit:

In case you don't want me to use automated tools to download replays from MX I can shut it down and instead allow users to upload replays themselves.

It's fine. Thanks for sharing/inquiring.
