Nice ! Do you only support some platforms (will love to know all supported platforms on your website)or can we also create images with counter based on external data sources (through an API)?
Blogger, Dailymotion, Youtube, Stackoverflow, Apex Legends, Division 2, CSGO, OSRS, Twitch, Wikipedia, Reddit, Github, Steam, osu!.
I'm expanding it with more data sources, and as you mentioned a Custom JSON Data Source. (You'll be able to enter your own URL, and rasterizer will pull a json from the URL)
