About

Codename One is an open-source framework for Java and Kotlin developers building native apps from a shared codebase. Listed targets include Android, iOS, macOS, web browsers, Linux, and Windows. Its toolkit draws its own UI components and bundles the runtime and theme with the application; developers can also call platform SDKs through native interfaces and embed views such as maps, web views, and camera surfaces. Current projects use Maven and can be opened in IntelliJ IDEA, NetBeans, Eclipse, VS Code, or another Maven-capable IDE. Documented sign-in options include OpenID Connect, Apple, Google, Facebook, Microsoft Entra ID, Auth0, and Firebase Authentication. Security guidance covers secure storage, encryption, certificate pinning, device integrity checks, and cryptographic APIs. The free cloud tier has 100 build credits per month, with iOS builds using eight credits, and an 8.5 MB user JAR limit. Commercial use carries no royalties or per-app fees. Paid plans start at $25/user/mo (annual), and a 14-day trial is listed.
