Microapps

Microapps are small, independent applications that perform a single function within a larger digital environment. They can be embedded in existing platforms or run as standalone services, usually built for a specific user workflow.

The concept emerged from the success of mobile app stores and microservice design. Organizations began producing microapps to accelerate digital transformation, allowing developers to iterate faster and users to access tailored tools without switching contexts.

Architecturally, a microapp consists of a front‑end component, a service layer, and optional data connections. It communicates with its host through well‑defined APIs or message buses. Its modular structure enables developers to swap or upgrade parts without affecting other components.

Key benefits include rapid development cycles, high reusability, isolated maintenance, and the ability to scale only the parts that need resources. Users experience a more cohesive workflow because microapps can be integrated directly into existing portals or chat platforms.

Challenges often involve managing inter‑app security, ensuring consistent data models, and preventing fragmentation of the user experience. Governance frameworks and shared design systems are needed to maintain coherence across multiple microapps.

Examples include SAP Lively on the SAP Business Technology Platform, Microsoft Teams apps, Salesforce Lightning components, and Atlassian Forge. These platforms provide runtime environments, marketplace distribution, and integration hooks that encourage broad adoption.
