How to choose
Which platforms does it need to run on?
Start with the devices and environments your app must support, such as iOS, Android, Windows, macOS, Linux, or the web.
Compare the platform labels for tools such as Android, Flutter, Ionic Framework, and Apache Cordova before choosing a shortlist.
Is there a free plan or trial?
Check the pricing note for a free plan or trial before committing. Apache Cordova, Capacitor, Dioxus, and Ionic Framework show free plans, while Delphi lists a 30-day trial.
Freemium tools can add paid service later: Expo Application Services lists paid plans from $19 per month, and Avalonia lists paid plans from €299 per user per year.
Do I need open-source code?
Choose an open-source option when inspecting or changing the code matters. Android and Flutter are marked open_source on this board.
A free plan is not the same as open-source code, so check both marks separately.
Which pricing model fits the project?
The list includes free, freemium, and open-source pricing models. Match the model to whether you need a no-cost starting point or expect paid features later.
Read the pricing note for limits and paid starting points, then confirm that the plan covers the platforms your app needs.
Which comparison marks should I check?
Use the public API, open-source, and free-tier marks to narrow the choices, then review platform support and pricing for the remaining tools.
An API is a way for software to exchange data; open-source code can be inspected under its licence, and a free tier provides a no-cost way to start.
