Abstract: This disclosure relates to systems and methods for providing an application services cloud based on text-based messaging that hosts a plurality of application services that enables applications to be designed and delivered in a simple, productive, and extensible user experience. The present disclosure transforms any device equipped with text-based messaging into a cloud computer, a thin client with connected access to cloud-hosted applications. The disclosure overcomes heretofore unsolved platform design and implementation challenges for text-based messaging applications such as issues of user interface constraints, security, service discovery, information filtering and tracking, platform integration and extensibility, and architectural scalability.
