What AI says about OpenFisca

OpenFisca is a free, open-source engine that lets governments and other stakeholders encode laws and regulations as code, and access them via a web API and a Python API to power apps and analyses. It enables collaboration across government, developers, and researchers by making policy rules computable, transparent, and easy to update when laws change, and supports simulating the impact of reforms on budgets and income distribution. Real-world use includes citizen benefit eligibility tools, MPs estimating fiscal impacts, and country-specific rule packages used to build policy apps and research simulations.
