re self-hosting: yep! Use the -devtools flag to get a stripped down version of Subtrace running entirely locally:

    subtrace run -devtools=/subtrace -- python3 -m http.server

This starts a Python server on localhost:8000 but with Subtrace. Everything except /subtrace is forwarded to the Python server like usual, but if you go to http://localhost:8000/subtrace you should see the Chrome DevTools network tab running in the browser like a regular app. Any request you send to localhost:8000 + all outgoing requests made from inside the Python app will automatically appear in that dashboard!
