I’ve had Corona SDK plugins in the Corona Marketplace for nearly 2 years now, and in that time the plugins have been free. This is largely because at the onset of the Marketplace, Corona Labs did not support paid community plugins. That changed late last year, when they allowed developers to charge for plugins and other development assets, much like Unity does with its own marketplace (among others). This has been a real boon to the Marketplace, as the number and quality of plugins has increased significantly now that developers can earn real money for their efforts extending the platform. I’m personally a very happy customer of many of my fellow plugin developers.
While I will continue to provide community support free of charge via this site and the Corona Labs forums, I have decided to start charging what I think is a reasonable one-time fee for activating my Corona plugins. Writing plugins takes a significant investment of time and energy, as does supporting them with bugfixes and updates, and I believe it is important for developers to value their time.
If you had previously activated either plugin, you can continue to use it for free – your license to the plugin(s) remains valid. These new costs will only apply for new activations.
As of today, I offer two plugins: a Twitter plugin which will now cost $2.99 to activate, and a Stripe plugin, which will cost $4.99 to activate. I hope that new developers will continue to find them useful additions to their Corona toolkits, worth the cost. Look for new plugins (at reasonable rates) from me in the coming year.
