Yes It would be really nice to have this kind of tools.
Doesn’t matter what language as long as it can run on a web server like ‘apache’ and co.
In my case, I’m interested in the old 16bits computer like Amiga and Atari.
Ex : Amiga500 or Amiga600 it’s a old 16/32 bits Computer from the 1990’s
There are many similar breakdowns on this kind of equipment like RESET_SIGNAL (generated by NE555 on Amiga500 for ex.)
Or just, to understand how a floppy_drive work, see INDEX, DIR, MTR_ON, DKRD, TK0… works when we make a DIR, READ TRACK, WRITE TRACK, FORMAT command on a floppy disk.
Understanding and seeing the mechanism allows for better repair for sure.
So, just, for me, for example, share a .SAL a RESET_SIGNAL it will be nice.
Each user can be, scroll in the time of capture (like logic2), zoom in on a specific area, display signal measurements when the mouse cursor is in a zone.
You can take a look at some of my pages :
