Sometime this month, 10 years ago, Rebrickable was released to the public. I didn’t take note of the exact date 🙂
Rebrickable was originally just for my own personal project. After coming out of my dark ages and buying a few large Technic sets, I thought there must be some other sets I can build using those parts. I created the database and coded up the first very simple Build Engine to answer that question for myself.
