Y Combinator startup Heroku, which has been in private beta since October, is coming out today with more details about how it’s out to ease the development and deployment of Ruby on Rails (RoR) applications.

There are two sides to Heroku’s offering. The first is a completely in-browser development environment where RoR programmers can build their apps instead of doing so with software on their own computers. Relative to other programming languages, Ruby and the Rails framework can be particularly onerous just to install and configure. Heroku wants both amateur and advanced programmers to get coding right away by making RoR development possible with any browser-equipped computer.
