How did twitter make bootstrap?

Bootstrap was an internal project by Mark Otto and Jacob Thornton in mid-2010.
Before it went opensource, it was known as “Twitter Blueprint”

After some months into the project, Twitter held its first HACK WEEK. During which, a lot of developers with different skillset and experience jumped into the project and the project exploded.!

Bootstrap served as a style guide for internal tools of Twitter for a year before its public release.
It is still being used on twitter, bits and pieces for the main “” and majorly for other
internal tools.


  • During the hack week, twitter employees make small teams and work on projects which are not a part of their day to day work. At the end of the week, they submit their projects to the management and they decide whether a project should be developed right away, or should it be kept to be developed in the future. The remaining projects act as inspiration. They also have a dedicated twitter handle for it : @hackweek
