So one needs to upload the trace log to your website to visualize? Any way to do it locally?

Absolutely, check out https://github.com/janestreet/magic-trace#privacy-policy and https://github.com/janestreet/magic-trace/wiki/Setting-up-a-.... With a bit of extra configuration, magic-trace can host its own UI locally. You just need to build the UI from source, and point magic-trace to it (via an environment variable).
