Interface Architect is a Cloud-based Microsoft Windows editing application which may be used for documenting the integration of systems within an organisation, by guiding users in the entry or automated-import of system interface details (eg program API signatures for RPC, flat-file definitions for ETL, XML and JSON definitions for middleware and SOA, and relational DB object signatures for data transfer), and defining the mapping rules that exist for communications between them and their associated non-functional requirements. A secure web-based UI is also available for sharing the interface information with invited users via the Internet.All information is securely-stored by Interface Architect using Microsoft Azure cloud services. Initial registration is required to obtain a login, the first 30 days of use (with storage limits) is free, after which a monthly subscription is required.

The creation of interface specifications is often vital for large distributed systems, for both their strategic design and future maintenance. Traditional methods for capturing these have included the use of Word documents and spreadsheets, which have proved difficult to standardise, version, and share accurate and complete information among team members. Interface Architect addresses these issues by providing an easy-to-use interface with tooling, a database back-end for shared storage and version, and also provide the ability to publish complete documents in MS-Word and Excel formats
