Does render have something similar?
This isn’t currently supported by Render. But I’d encourage you to open a feature request with your usecase at http://feedback.render.com so we can track interest and notify you of any updates.
In the interim, have you looked at a service like prerender.io? I´ve used them for years and had good experiences with them.
