B4X vs DroidScript

B4X is a suite of rapid application development tools for Android, iOS, desktop, server, and IoT projects. Its B4X language is described as a modern version of Visual Basic, and B4A, B4J, and B4i projects can share 90%+ of their code through cross-platform libraries. B4A includes a GUI designer for multiple screens and orientations and supports device debugging over USB or a wireless bridge. B4J creates desktop interfaces, console programs, and server solutions that can run on Windows, Mac, Linux, and ARM boards such as Raspberry Pi. B4R targets Arduino, ESP8266, and ESP32. The maker says compiled iOS, Android, Arduino, and ESP8266 applications are native and have no dependencies. B4A, B4R, and B4J are free, including for commercial purposes. Standard B4A and B4i licenses cost 59.00 USD once per developer. B4i requires an Apple developer account costing $99 per year, an iOS 11+ device, and Windows 7 64-bit or a VM for its IDE.

DroidScript is a coding tool for making native Android apps with JavaScript or Python, as well as HTML5 apps. It is described as non-cloud-based and usable without an internet connection. Its WiFi IDE runs in a browser and can remotely control, edit and debug apps on connected Android devices over WiFi. Documentation, runnable examples and samples support learning and setup. An APK Builder plugin can build apps for release on Google Play. Listed plugins cover barcode reading, GoPro control, Lego Mindstorms NXT, Sphero and MOGA gamepads. Users can make private or open-source plugins with the Plugin SDK and extend the WiFi IDE. The tool includes a visual UI designer and supports Android, Amazon Fire and ChromeOS targets, with Windows, macOS and Linux desktop platforms. DroidScript is free, with optional paid plugins and donations. Its site points users to a community forum and lists an email address for support; it describes the organization as not-for-profit.
