Why it matters for engineering teams

Expo addresses the challenge of building truly universal native applications that run seamlessly across Android, iOS, and the web using a single codebase in React Native and TypeScript. It provides a comprehensive open source tool for engineering teams aiming to streamline cross-platform development without needing to manage complex native build configurations. This framework is mature and widely adopted, with a strong community and proven reliability in production environments. It suits roles such as mobile developers, frontend engineers, and full-stack teams focused on mobile and web integration. However, Expo may not be the right choice for projects requiring deep native customisation or where a self hosted option for native modules is essential, as it abstracts some native capabilities in favour of ease of use.

When to use this project

Expo is a particularly strong choice when teams want to accelerate development of cross-platform apps with consistent UI and shared logic. Teams should consider alternatives if their app demands extensive native code customisation or if they require full control over native dependencies and build processes.

Team fit and typical use cases

Mobile developers and frontend engineers benefit most from Expo, using it to deliver production ready solutions that work across mobile and web platforms. It is commonly employed in consumer-facing apps, internal tools, and startups aiming to reduce development overhead. Engineering teams appreciate its ability to simplify deployment and updates without sacrificing performance on Android and iOS devices.
