About AHEMAHEM is a next generation free temporary email address service.
AHEM focuses on a modern UI, high fidelity, mobile friendliness, an easy to use API and freely available code.
AHEM was born of out of necessity, and was built as a weekend project by Oren Geva.
It is not a business, and has no profit goals. If ads are included in the service it is to help maintaining this service free.
AHEM was built as a MEAN stack, using Angular, NodeJS, MongoDB and ExpressJS on top of some awesome open source packages. Check out the github repo for a complete list and licenses.
I would, however, like to mention one of those projects - Nodemailer by Andris Reinman. THis project serves as the core of the mail server part of AHEM, and therefore is very central to this service.
