I've asked on Twitter what are the choices.

Dokku on Digital Ocean was suggested. I'm going to check it out.

I've developed assuming the economics would stay constant. The changes I think I may have to make are not small. And how much time do I have to react? It doesn't seem to say. Oy.

Heroku has never been that good at communicating, they speak a language I don't understand. But this time I have to understand what they're saying.

Also, I don't see myself as a hobbyist.

I don't like that they call me that.

Reading further it does say how much time we have. Until June. That is ridiculous. Right now I feel really abused. What if I had other plans for the month of May other than migrating all my stuff to their new model, or more likely off Heroku altogether? I've had one vendor do this to me in all the years I've been building Internet apps, and that was early days, and they went out of business shortly after they forced us to do a similar emergency migration.

One thing you have to do, if you want to have any goodwill left, is change June 1 switchover date to something more realistic for people who built on your platform assuming the model would stay more or less constant.

Facebook just gave developers one full year to transition to a new API. I thought that was fair.

I don't think you understand what it's like to hear this kind of news. I put apps on Heroku thinking they're done, I don't have to think about them, they just run.

Had I had the slightest inkling the model would change, I would have done things dramatically different.

Most of the apps I have on your service, if not all, will have to come off your service. I think giving us less than a month to figure out how that works is the most awful thing you could do.

Tell me I misunderstood.
