fullapp

Fullapp is a term used in software development to describe a self-contained application that provides a complete set of features for a given domain, typically delivered as a single, cohesive product rather than as a collection of loosely coupled services. It emphasizes end-to-end functionality within one application boundary, though it may still use external data sources or services when needed.

Typical characteristics include a single codebase, an integrated user interface, and built-in business logic, data access, and deployment packaging. A fullapp often covers authentication, data storage, reporting, and offline or synchronized capabilities. It is designed to run on desktop, mobile, or web platforms, with most core features accessible from one instance.

Fullapps are often contrasted with distributed architectures such as microservices. Benefits include simpler deployment and easier testing of end-to-end user flows, while requiring less inter-service coordination. Drawbacks can include limited scalability, slower iteration on individual components, and the risk that a large monolithic codebase becomes difficult to maintain.

Design and development practices focus on a clean internal structure, clear separation between layers, robust data models, and a consistent user experience. Developers may use full-stack frameworks or platform-specific toolchains that support rapid development of integrated features, along with strategies for reuse and maintainability.

In practice, the choice between a fullapp and distributed approaches depends on project scope, team size, time-to-market needs, and scalability goals. The term is descriptive rather than a formal standard and is often used to signal a baseline of completeness for a domain.
