I have spent some time now putting together another application called sondd.
I guess the simplest way to describe sondd is it allows you to transfer up to 3gb to anyone with an email address. You can use the service without registering, or you can sign up and manage sent & received transfers, as well as any contacts you send to.
It is essentially We Transfer with a greater send limit.
There is quite a lot of backend workflows running that are required for the management of uploaded files, any unsent files after uploading, transfer expirations, receiver/sender information, and the managing of files should they be forwarded to more than one user.
In the beginning, this was a project to spawned purely from boredom and ended up testing some skills in some complex workflow setups. I am considering listing this as a template should anyone wish to start their own We Transfer, but I will wait for an expression of interest.
