Alternatives to Codename One

{"intro": "Codename One gives Java and Kotlin developers a shared codebase for native applications on Android, iOS, macOS, Linux, Windows, and the web. It draws its own interface components, packages the runtime and theme with each application, and exposes platform SDKs and heavyweight views through native interfaces. Maven projects fit several IDEs, authentication options include major identity providers, and commercial use has no royalties or per-app fees. Security tools cover storage, encryption, certificate pinning, integrity checks, and cryptographic APIs. The free cloud tier allows 100 build credits monthly, with iOS builds using eight credits and an 8.5 MB user JAR limit; paid plans start at $25/user/mo billed annually.\n\nReaders may prefer another tool for QML and JavaScript, HTML5 hybrid development, C++ workflows, game creation, rapid Visual Basic-style development, or visual enterprise app design. Compare languages, target platforms, UI approach, build and debugging workflow, integrations, testing, support, and deployment requirements. Codename One spans mobile, desktop, and web, but its free cloud allowance is limited and its programming center is Java and Kotlin.
