GameSalad vs GDevelop

The Windows version is now upto date with all the features of its Mac sibling.

Can create and publish games for iOS, Macintosh desktop and laptop computers, Android, Kindle, Amazon FireTV and FireTV Stick, Windows 8 and Tizen devices.

Gamepad support is available as of 0.13.3.

The GameSalad Viewer is a free app available for iOS, Android and Kindle. Once installed on your mobile devices, you can deploy and test your GameSalad games live on any mobile device running the Viewer that is on the same local network as your dev computer.

This even allows Windows users to test their games on iOS devices without a Mac device and without any complicated code signing or provisioning profiles.

And, you can even take your games with you -- once loaded onto your mobile device, a history option caches recent games on your device without any connection to the dev computer.

Since the user mainly uses menu options there is very little code needed to be keyed in. This makes the code very easy to read and understand.
Hence there are many help videos on youtube

Extensive community of seasoned professionals in all disciplines (graphics, game design, animation, physics, music, video production, marketing, etc.) producing tutorials, videos, publishing tips, free templates and who are willing to answer forum questions and help newcomers.

Allows you to create expressions on par with LUA (it's back end-language).

Allows you to import JSON data for custom collision shapes to use with Gamesalad's implementation of Box2d physics.

Software prepares your app so you can just send it to Apple. All my games are reviewed with no problems.

The drag and drop editor makes GameSalad very easy to use, no programming experience needed.

Very quick to learn and great for making games. Community is very open and helpful.

GDevelop's runtime libraries are MIT licensed. It can be used freely for projects of any type and there are no royalties associated with publishing games developed with GDevelop.

The whole interface is intuitive and easy to learn: each part of the game can be designed using visual editors. The objects editor is used to create the objects of the game, the scene editor help you to build the levels of your game and the events editor allows to give life to the whole game without programming.

No need for coding using this system which is clear and powerful: events are composed of conditions and actions. Actions are launched when conditions are fulfilled.
This is a very friendly way of making games and is still efficient for advanced usage, contrary to most other "block"/"drag'n'drop" systems.

The plugin SDK is open source, so if you want to extend it, you can.

The engine includes pathfinding, physics engine, multitouch support, custom hitboxes, platformer engine, tiled maps, multiple layers and cameras out of the box.

All of these features can be used without programming knowledge, using the visual editors.

Prebuilt behaviors can be added to objects. This is a very efficient way to add a physics engine or make a platformer game. Lots of behaviors are included, from the most advanced (Physics, platformer, top-down movement) to really simple one (like the behavior to destroy objects when outside the screen or the one to drag objects with mouse or touch).
And you still have full controls over your game as behaviors can be modified using the events!

GDevelop is able to create HTML5 games that can run on web browsers and be exported to iOS and Android using solutions like Intel XDK or Cocoon.JS.
GDevelop is also one of the only friendly game creator that is able to make native games for Windows and Linux, which are blazing fast and allow to make advanced games with lots of objects, effects and very large levels.

A new doc is improving for gd5 that is nice for beginners and after that you can learn more from examples. Also, gd4 wiki is still there.

GDevelop is available in many languages and even community can help in translations.

Thanks to its open source nature, GDevApp.com was built over the GDevelop engine.
GDevApp.com is a complete game creator similar to GDevelop, available directly in your browser and compatible with iPad and most Android tablets and phone! The app is perfect for making games directly from your sofa and you can even start a game on GDevApp and export it to open it inside GDevelop.

New releases and bug fixes are consistent. New updates are released anywhere within 2 weeks or 1 month from the last one. Its auto-updater also does it job very well making life a lot easier.
