I'm just curious
How much the game website server will cost, Like miniclip and kongregate, armorgames.
How much thy pay for the host every month?
you should hit a email to gamejolt.com, they dont have the same size as those 3 you listed but i think the guy behind it is more vocal about technical details
Develop games in your browser. Powerful, performant & highly capable.
You need to host it somewhere else and give them the link for Kongregate.
They will iFrame it into their site.
You should be able to find some free servers out there that you can use.
