GameSalad vs PlayCanvas

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.

PlayCanvas has an online editor that lets you build scenes and work with other people in your team in real-time. This is all done through the web browser without having to install any additional software.

Assets and content delivery is very different on a web platform comparing to native. So PlayCanvas challenges best practices to allow developers decide how their content is delivered and in what form.

Async Assets download allows developers to load content as the app goes, instead of asking to download all assets in advance risking users to simply navigate away while staring at loading screens.
Formats for 3D models and textures support covers all the popular tools. And the workflow is as simple as dragging and dropping your files right into the Assets Panel. The cloud will do the rest of the hard work optimizing and converting your files into runtime-friendly and compressed data.

Has an advanced WebGL renderer that runs in the browser.

Lightmaps are an efficient way to deliver lighting to your scenes for a long time. But they come with the cost of large textures. PlayCanvas offers a unique solution for a web platform, it renders lightmaps when an app is loading in runtime.

This is faster than downloading MBs of textures. And it's much more convenient: simply switch your light sources to bake, and static models to be lightmapped, and the engine will do the rest.

PlayCanvas has Feed as homepage for registered users, listing Dev Logs of other developers. This allows to socialize with other developers like yourself in a twitter-like environment.
More to that, there is also an active forum, where developers help each other to solve their challenges.

Developers of PlayCanvas itself are always looking forward to chat and help the community with any problems that may arise.

PlayCanvas lets users integrate physics in their game rather easily, using the powerful Bullet Physics Engine (ammo.js). Should also be noted that the physics engine is delivered as an optional library, so by default being disabled it does not add any extra download size to your apps.

Engine is free for projects under 200MB and with no more than 2 people on a team. The free tier has no engine restrictions.

Tools are totally free too. There are no special limiting features behind any paywalls, and free users have all the features as paid users.

There are no royalties associated with publishing your apps and games - you've made them, you own them.

It is free to publish to playcanvas.com as well, just by one click in Editor.

PlayCanvas lets you build games that run in mobile, desktop browsers, and native mobile apps. PlayCanvas can even make games that can run inside mobile social media and instant messenger clients like Twitter and WhatsApp.

The engine itself weighs just under 150Kb, and it's always challenged to stay small. There is no extra weight that has to be carried with your app, just your assets and scripts in a runtime-friendly compressed form.

This allows users to engage with your content in matter of seconds, and even just under a second on a good connection.

PlayCanvas is fully open source and is under active development.

Real-time link between your launched app and the editor allows the developer to preview and play with their scene without needing to refresh the game after every change in the code to see the updated result.
