Contratobook — Open-source platform allows citizens to audit government contracts
Launched in Mexico in October 2016, Contratobook is an open-source platform that allows users to search, filter and comment over 1.5 million government bids and contracts. Dating back to 2002, each entry details contract values, involved parties and start date, allowing users to detect irregular or inaccurate expenses. Notable irregularities are detailed on an affiliated Twitter account. Contratobook was developed by a group of anonymous hackers.
