Hi @craynic, thanks for this!

Could you please add:

• An example-dump.txt file with an example thread dump

• A clickable URL to both index.html and README.md showing how to use the by-query-string feature to analyze the example dump.

  Regards /Johan

It could be a demo for this feature.

I don't known how to write a readme. Is there any sample or template?

There's a README.md file at the top of this repo, just add it there!

And to the index.html, since that's what people will see when they just come from Google or wherever.

I just realized I don't think this works across domains; if I merged this it would only work for URLs on the spotify.github.io domain, which would be pretty useless.

For a demo, try this link and watch your Javascript console, note the CORS warning:
http://craynic.github.io/tda/index.html?url=https://www.kth.se

Google "CORS" to learn more, but I think it's not possible to get this working cross domains :(.

Sorry I'm a little busy these days. In our usage we do serve the script and stack files on a same domain.
Very sorry for that. I will close this PR.
