Corona is a software development kit (SDK) developed by Corona Labs Inc. Corona allows software programmers to build 2D mobile applications for iOS, Android, and Kindle, desktop applications for Windows and OS X, and connected TV applications for Apple TV and Android TV.

Corona uses integrated Lua layered on top of C++/OpenGL to build graphic applications. The software has two operational modes: the Corona Simulator and Corona Native. With the Corona Simulator, you build your app directly from the Corona Simulator. Corona Native allows you use Xcode or Android Studio to build your app and include native features.


Walter Luh and Carlos Icaza started Ansca Mobile, later renamed Corona Labs, after departing from Adobe in 2007. At Adobe, Luh was the lead architect working on the Flash Lite team and Icaza was the engineering manager responsible for mobile Flash authoring. In June 2009, Ansca released the first Corona SDK beta free for early adopters.[1][2][3]

In December 2009, Ansca launched Corona SDK 1.0 for iPhone. The following February, the Corona SDK 1.1 was released with additional features.[4][5]

In September 2010, Ansca released version 2.0 of Corona SDK and added Corona Game Edition. Version 2.0 added cross-platform support for iPad and Android, while Game Edition added a physics engine and other advanced features aimed specifically at game development.[6][7]

In January 2011, Corona SDK was released for Windows XP and newer, giving developers the opportunity to build Android applications on PC.[8]

In April 2012, co-founder and CEO Icaza left Ansca, and CTO Luh took the CEO role.[9] Shortly after, in June 2012, Ansca changed its name to Corona Labs.[10] In August 2012, Corona Labs announced Enterprise Edition, which added native bindings for Objective-C.[11]

In March 2015, during GDC 2015 announcement was made that Corona SDK is completely free and will support Windows and Mac OS X deployment targets.[12][13]

In November 2015, Corona Labs Inc. announced support for tvOS development for Apple TV.

"In March 2017, Corona Labs was acquired by Appodeal and announced that the Enterprise version of Corona would also become free.[14]

In June 2017, Corona Labs announced that Enterprise was renamed to Corona Native, is free for everyone and included as part of the core product."[15]

Major features[edit]

Corona's API suite features API calls for audio and graphics, cryptography, networking and device information such as accelerometer information, GPS, and user input as well as widgets, particle effects, and more.[16]

Corona third-party tools and services[edit]

Corona includes the following third-party tools and services:

  • Kwik is a plugin that allows Photoshop users to create mobile applications for iOS and Android devices with Corona SDK. Graphic designers, writers and illustrators can create mobile applications in Photoshop, and publish using Corona SDK without the need for coding.
  • OneSignal is a plugin and platform as a service to send push notifications to iOS and Android devices.[17]
  • Lua Glider is an IDE that features a debugger, variables explorer, call stack, adaptive auto-complete, built in documentation, real-time breakpoints, split screen support, asset preview and simulator remote.
  • Corona Complete is a visual debugger, code editor and project manager for Corona SDK. The tool offers smart auto complete, variable memory dumping, console output, file management, error and breakpoint management.
  • Spriteloq is an Adobe Flash SWF exporter for Corona SDK that allows developer to integrate Flash art and animations into mobile applications.
  • Lime is a Lua library created for Corona SDK which allows game developers to include tile maps created in Tiled within a game. Tiled can be used as a level editor and as a property feature that allows level designers to set up game logic without the need for a programmer to change any code.
  • SpriteHelper is a Mac OS X application that brings developers a texture and a physic shape editor in one package.
  • Corona Textmate Bundle is designed to help TextMate users code Corona SDK applications more quickly. It contains a large number of autocomplete terms, commands, and snippets for access to various Corona APIs using the standard TextMate keyboard/menu shortcuts.
  • Particle Candy is a particle engine library that allows developers to create smoke, trails, fire, explosions, debris, flares, dust, clouds, shots, light rays, water fountains, and weather effects.
  • MultiRezer is a utility for developers to port games and applications to multiple devices, by rescaling graphics to fit a desired device. The tool currently supports over 10 devices, including the iPad 3.
  • LevelHelper is a level editor for Mac OS that helps populate game worlds. Used in conjunction with SpriteHelper, developers can import sprites and create levels by dragging sprites in a desired position.
  • Icon Robot is a tool that generates different size iOS icons by resizing and exporting application icons.
  • Corona Remote is an application and Lua library designed to send remote accelerometer data to Corona SDK. Using an iPhone 3G, iPhone 3GS, iPhone 4, iPod Touch or iPad, developers can send real-time accelerometer data to the Corona Simulator for use when developing accelerometer-powered applications and games.
  • Texture Packer is a graphical user interface that offers multi-touch support, zooming and a tree view with sprites and shows changes in real time.
  • Physics Editor helps developers edit physics shapes. By drag shapes inside the editor and pressing the auto trace button, developers can adjust the shape’s physics parameters and directly export to a game development framework.
  • iAppHost creates iPhone application websites with a custom CMS that accounts for HTML, CSS and analytics.
  • Outlaw (formerly Corona Project Manager) [18] manages projects and assets so developers can switch from one application to another and swap out assets.
  • 700 Sprites is very useful because it provides a wide range of fantasy themes for application development.
  • bmGlyph is a bitmap font generator. Wide range of styles are available like Gradients, Glossy, Shadows, etc..
  • Explosion Generator 3 uses advanced engine mechanics to create perfect explosive effects in a simple way. This can be a major asset for Game Development.
  • Game Coder is a platform dependent application that can be used to develop applications on iOS. It provides the option of exporting the code into the Corona SDK and can be edited. And it can latter be published on the App Store.
  • Glitch Games Libraries are a set of libraries that can be used to speed up the development time.
  • Glyph Designer is a bitmap font generator that helps to add effects to any kind of fonts. Glyph Designer also has command line support allowing the process of generating multiple fonts at different sizes to be added to your automated build process.
