I'd avoid hosting the library on-premise and building a REST API. That adds unnecessary complexity and maintenance overhead. Go with the custom buildpack!

That's a valid point, Gilma. Option A could be a good choice for ensuring easy access to wkhtmltopdf on Heroku.

I disagree, I believe option A is the way to go. Fetching the library from cloud storage on dyno restart would ensure smooth operation on Heroku.
