Canva gives you a beautiful canvas and a human to drag things on it. OpenGraphAPI gives you a URL: swap two words in a query string and a fresh 1200×630 PNG appears — for every post, product, student or episode you have. If you make one image a week, use Canva. If you make one image per article, per product, per graduate — you need a URL.

Canva's API access is limited to enterprise customers. For programmatic OG images you need a dedicated image API like OpenGraphAPI.
