Looks great! Reading through the docs it seems the subtrace process sends all data to your server. I'm reluctant to do that on a production environment, where API keys and personal data are being handled.
Is there any way to run it completely self hosted? If not, are there plans? And how will you monitize self hosted options (if it's possible)?
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
That would work for a single instance, but when running multiple (e.g., you are horizontally scaled) it would not be ideal.
Is it possible to mimic "subtrace.dev"? There's the 'SUBTRACE_ENDPOINT' environment variable which can be used to set the target endpoint, but is the server side open source too? And does the license grant permission for self hosting the full stack?
Disclaimer: I'm a maintainer of the project
Pixie [1] is a similar project and offers the self hosted model you are looking for.
We also support 11 application protocols [2] with TLS handshake tracing and MQTT support coming soon (encrypted traffic tracing has been supported for a long time).
