# Catalyst APIs

Catalyst provides a set of APIs that allow you to easily build distributed applications.
These APIs are based on the popular open-source project Dapr. The APIs are designed to
provide powerful abstractions that drastically increase your productivity whilst also
providing a layer of portability across different infrastructure providers.
Currently, Catalyst supports a subset of the open-source Dapr APIs which are documented
in this specification.
