Corona Labs was a software development company known for creating the Corona SDK, a popular cross-platform development framework used for building 2D mobile applications and games. The framework allowed developers to write in Lua, a lightweight programming language, and facilitated easy deployment across multiple platforms, including iOS, Android, and Windows. Corona SDK was particularly praised for its ease of use, rapid development capabilities, and a strong community support system. The company provided resources such as tutorials, documentation, and a community forum to assist developers in their projects. However, it's important to note that Corona Labs discontinued new feature development and new platforms as of April 2020, and the core project has been transitioned to an open-source model.
