WkHTMLtoPDF Service

I've been noodling on html to pdf conversion lately. This is the first result of that. What do you think?

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".

I currently run wkhtmltopdf and it takes a whole additional dyno in Heroku. I spend a lot of time dealing with large payloads that end up crashing and I would rather have a bulletproof service I can deliver that payload to and have a PDF come back without me needing to pull my hair out constantly.
