We got in contact via discord, sharing different developer ideas. Our projects are similar, but our target audience differs.

Bruzu - You can call an API link to instantly generate an image, text data / image data can be swapped out on the fly.

Rasterizer - You design an image and then once saved, it provides you with a static URL you can share and this static image updates when your data source updates.

Also I've fixed the github data source, as he found it wasn't working properly.
