India Stack is

A vision for the world / a vision for India

A vehicle for financial and social inclusion

National plumbing for the Internet Age

A collection of open APIs empowering people and businesses

Inspired by the principles of open-source software and interoperability

India Stack is the moniker for a set of open APIs and digital public goods that aim to unlock the economic primitives of identity, data, and payments at population scale. Although the name of this project bears the word India, the vision of India Stack is not limited to one country; it can be applied to any nation, be it a developed one or an emerging one. Having said that, this project was conceptualized and first implemented in India, where its rapid adoption by billions of individuals and businesses has helped promote financial and social inclusion and positioned the country for the
Internet Age.
