Does bors-ng run on heroku's free tier?

I installed it there to test it on one of my repository PRs: https://github.com/BioJulia/FASTX/pull/1

But after I do a “bors try”, I see the try commit passes travis, but bors does not comment, until it says that it timed out.

I followed the link, and it seems like you got it to work. What was wrong?

AppVeyor wasn’t configured correctly, so Bors was waiting for it until timeout.
I’ve set it up now to run on a 2nd repository: https://github.com/BioJulia/BioGenerics/pull/1.
It appears to be working and everything passing, but it seems to take time for Bors to report back and say the build completed.

That’s typical for running on Heroku’s free tier. Bors-ng runs on it fine, but it gets stopped and started and that’s kind of slow.
