releas.io is a home-grown organic service to generate download cards for your physical music releases.
Easy! Simply upload your digital release (as a zip file or whatever else you want), generate and print downloads cards and insert them into your physical packages (CD, vinyl...). Then, just embed the download widget onto your site or Facebook page and your fans will be able to redeem their card in a seamless manner. You can even collect their email addresses!
Well yeah, you figured it out, it can't be free. Indeed, I have to pay for servers and storage and all that stuff. Still, I want it to be dead cheap. So it easy, it's only 0.10 € per card.
releas.io is a one-man operation run by @neutralino1. Feel free to get in touch if you've got questions or if you want to collaborate. I'm based in Paris so if you're around, let's grab a coffee (or something...).
I'm easy to get in touch with. Drop me a line at manu at releas dot io or tweet me up at @neutralino1.
