Why it matters for engineering teams

Expo addresses the challenge of building truly universal native applications that run seamlessly across Android, iOS, and web platforms using a single codebase in React and TypeScript. This open source tool for engineering teams simplifies mobile development by providing a consistent framework and a rich set of APIs, reducing the overhead of managing separate native projects. It is well suited for frontend engineers and mobile developers who need to deliver cross-platform apps efficiently without deep native expertise. Expo is mature and reliable enough for production use in many scenarios, with a strong community and ongoing maintenance. However, it may not be the right choice when apps require extensive custom native modules or performance optimisations that demand direct native code control, as Expo can impose some limitations in these cases.

When to use this project

Expo is a particularly strong choice for teams aiming to accelerate cross-platform app development with a production ready solution that covers most common use cases. Teams should consider alternatives if their projects need advanced native customisation or if they require a self hosted option for native build and deployment workflows.

Team fit and typical use cases

Frontend engineers and mobile developers benefit most from Expo, using it to build and maintain universal apps with shared React codebases. It fits well in engineering teams focused on consumer-facing mobile and web products where rapid iteration and consistent UI across platforms are priorities. Expo's framework integrates well into environments where an open source tool for engineering teams is preferred to streamline development without sacrificing production readiness.
