We’ve been working our tails off over the past few weeks to process all the feedback you guys have been sending (or that we’ve gleaned from the system logs). I think that this photo of the trashcan under Orion’s desk tells the story pretty well:

He bought that case of Rockstar at Costco last week, and consumed it all as part of our mad dash to squash bugs exposed by our sudden surge of users. Bad for Orion’s health, but good for Heroku’s backend stability. :)

One major area we’ve been dealing with in this past week is the issue of failed mongrel starts. That is, exceptions that occur while the Rails framework is booting, rather than on a page request....

What about gems, plugins, and different Rails versions?

We are definitely going to support gems and plugins. We are almost finished with a slick gem and plugin installer you can use for each app. In the meantime, you can install plugins by importing or uploading the files directly into vendor/plugins.

Currently, we only support the latest stable version of Rails. You can use a different version by uploading a frozen vendor/rails, but this may not work because of the 10MB storage limit constraint (rake rails:freeze:edge won’t work, by the way, because there are no outgoing network connections yet – we’ll discuss this in more detail in another post). We hope to be...

How long before I get in?

We are sending out tons of invites every day. We’d prefer not to have a waiting list, but doing it this way allows us to let people in only as we’re sure our infrastructure can handle the load. The number of people we let in each day keeps increasing, as our existing users give us feedback (thanks guys!) which helps us improve our product for the next batch of people coming in.

One of the areas we are most interested in is collaboration – this is, after all, a web application. We want to encourage existing users to invite their friends to become users and start collaborating with them, so we have given existing users the ability invite friends...

A couple of weeks ago we quietly started accepting signups for our private beta. We knew people would be excited about Heroku; I mean, we’re pretty excited about it. Word seems to have gotten out, as over the last several days well over 1,000 people have signed up.

We are inviting users off the waiting list all day, every day, as fast as we can. So we’re also receiving a constant stream now of feedback email. Some quotes:

OH – MY – GOD, Heroku! It’s absolutely great. In my opinion, it’s really a revolution in Rails development. – Chris

Wow. This is impressive, I like what I see. – Ben

This is exactly what I was looking for right now....

Unless you’re a big company with lots of marketing dollars, rarely does a product launch start with a bang. It’s a gradual process – first you show a few close friends and family members, then some coworkers from your previous job, then some friends of friends. The word starts to spread as you and your partners furiously hack away, trying to make the product stable enough to stand up to a pummeling from the general public. So there’s no big kickoff; just a quiet emergence. And if your product offers something of real value, awareness in your target market will grow steadily and strongly over time.

So it is with Heroku. James, Orion, and I have spent the last...
