How to choose

Which platforms does it need to run on?

Start with the operating systems your app must support, such as Windows, macOS, Linux, iOS, Android or the web. Platform coverage differs, so confirm support for your target before comparing other features.

How does it share code between platforms?

Check the shared code model and whether it fits how you plan to build and maintain the app. Also compare supported languages and app types; a framework's fit depends on what you are making.

Can I start for free, and what does it cost later?

Compare the free plan and paid starting price. A free plan is different from a free trial, so check which applies and whether the listed price matches your budget.

Will it work with my development tools?

Check IDE support and native API access alongside the target platforms. Native API access can matter when an app needs features tied to a platform.

Questions

What should I compare when choosing a cross-platform app framework?

Which platforms do cross-platform frameworks support?

Coverage varies. The platforms compared here are Windows, macOS, Linux, iOS, Android and the web.

What does shared code model mean?

It describes how a framework shares code across the platforms it supports. Compare the listed models to find a fit for your app.

Why should I check native API access?

Native API access may matter if your app needs features tied to a particular platform. Compare it along with platform coverage and app type.
