The latest addition here is to show how to capture screenshots from locally rendered HTML/CSS - perfect for social banners. Sites like Banner bear (no affiliation) are charging a fee for this kind of function, and all the better for it. Folks should charge for their work.

But if you are comfortable hosting openfaas (3 EUR / mo on Hetzner using faasd) then you can do it a lot cheaper and run additional webhooks / APIs / blogs / integrations there too.

A banner generation website will cost 49 USD / mo for 1000 images, 99 USD / mo for 10,000 images. Or 3 EUR / mo for faasd.
