As previously announced, I have spent most of the last year on completely rebuilding Rebrickable from scratch. I am now opening up the testing site for access to everyone, please take a look around and try it out!
About 6 months ago I announced that a completely new Rebrickable is on it's way. I've been hard at work making that happen, and we are getting closer.
For the last few months I have been working on the next major release of Rebrickable. That's a bit of an understatement actually - I'm rewriting every single aspect of the site from scratch! I'm calling it Rebrickable v3.
