This would be perfect on hosting services like Heroku where you want to avoid having to run a heavy library like wkhtmltopdf. Seems like this will inevitably save people money because they can keep their own servers slimmer and scale them more horizontally without having to worry about the memory requirements of something like wkhtmltopdf when it's generating large documents.
I'm sure I'm not the only developer who has had to configure this in a production environment and thought to themselves "this really should be a SaaS".
