It's actually pretty cool. I've just been through all of that painful setup personally. CORS, grunt, SSL, cloudfront, S3, deploy, different stages, minifying, zzz. As others have asked, how do you plan to price such a service? A feature from Heroku I really like is the "Rollback", maybe that's something you may want to add as an added benefit.
Thanks for the feedback. Pricing plan is free for indie devs/small apps, business edition to come with better team support and enhanced backend integrations.
I assume by "rollback" you mean reverting back to a previous app version. With our traffic control rules you can apportion traffic to 1 to many versions at once. So in a simple rollback scenario you would just point 100% of the traffic to a previous version (no redeployment necessary). However you can also do interesting things like direct only 5% of users to a new version or require a special preview link to see the latest version without impacting normal site traffic.
