This buildpack sets up a Tor hidden service for your app on Heroku.
Create a Heroku app as normal, with any buildpacks you typically use. If you have a Go app, for instance, deploy it as normal.
$ heroku buildpacks:add https://github.com/apg/heroku-buildpack-tor.git
With the buildpack installed, you'll need to modify your Procfile such that the hidden service will be setup when the app runs.
web: hide <cmd you'd normally run>
web works just fine, so too will any other process type. Use
if you want the app to be accessible generally, as well as over Tor. Use
<any other type>, to avoid Heroku's router routing to your app like so:
foo: PORT=9999 hide <cmd you'd normally run>
Your app will only be accessible over Tor, through your configured
Of course, Tor hidden services require that you provide a private_key and it's SHA, for the .onion name. You'll need to provide these as env vars:
HIDDEN_PRIVATE_KEY: The contents of a private_key file
HIDDEN_DOT_ONION: The onion name for the private_key.
The easiest way is to:
$ heroku run bash heroku$ mkdir hidden heroku$ echo "HiddenServiceDir /app/hidden/" > tmptorrc heroku$ echo "HiddenServicePort 80 127.0.0.1:8000" >> tmptorrc heroku$ tor -f tmptorrc heroku$ cat hidden/* heroku$ ^D
Copy the snippet above into CLI.
