The Hacker Laboratory of the Chamber of Deputies is a laboratory for innovation within the Chamber of Deputies open to citizen participation. It was created in 2013 as a permanent hackerspace after the completion of the first hackathon for parliamentary transparency projects. It is the first case in which a laboratory for innovation is institutionalized in the Legislative Branch. Its objective is to develop E-Democracy platforms in the framework of other activities that increase citizen participation in the legislative process, in addition to increasing transparency. All the tools developed are open source and the lab is also open for any compromise.
