Anyone building something for all SmugMug customers to use, we'll start you off with a free full featured Pro account with all the bells and whistles for 1-year! If you continue to fully support your application, enhance it and fix bugs, we'll make that account free even longer. Simply send an email to API@smugmug.com letting us know what your application will do, a link to it if it is already under development and a link to some of your prior work.
Already have an account? Just include it in your email. Don't have an account yet? Do not start a trial, email us at the address above and we will get you setup.
