xyz_ ,

Still cant get it to open a single file sadly.



Developer Response ,

Does it work inside the app? Or files cannot be opened from the Files app? Some files extensions cannot yet be opened from Files app or other applications.

Local Sever Functionality is Fantastic

The code editor itself is whatever, but the ability to view local web projects in Safari is fantastic for my web dev projects. Since the app is integrated with the iOS Files app, I use Edidown to host the project and other coding apps to actually write the code. This app has made my iOS web workflow so much better.

One critique of the hosting functionality I have is that all my pages seem to have %BODY% text at the top of the page. Is there any way this can be removed? If not currently, that would be very much appreciated in a future version.
