Before you choose
Match the target platforms
Start with the platforms your app must support. Entries span Windows, macOS, Linux, iOS, Android and the web.
Check the target-platform field before comparing other details. A framework that does not cover a required platform may not fit the project.
Read the pricing model
Check each entry for a free plan. Freemium entries can also show a paid starting price.
Published paid-from figures include €299/user/yr for Avalonia and $59 for B4X. Check the plan notes before budgeting.
Compare the shared-code model
The shared code model describes how code is reused across targets. Compare that field with the app types and languages your project needs.
Also check native API access when the app depends on platform-specific capabilities.
Check the development workflow
IDE support can affect how the team writes, builds and maintains the app. Compare the listed IDE support with the tools already used by the project.
App types and languages provide another way to narrow the choices before reviewing platform coverage.
Use available trial paths
Check individual entries for free-trial availability. Use a trial when you need to check whether the workflow, language or IDE support fits before choosing a paid plan.
