Congratulations on the launch, and good luck finding a sustainable means of funding Caddy. It's a uniquely ergonomic webserver.

That said, the unalterable Caddy-Sponsors HTTP header feels bad, and cheapens my overall impression of Caddy as a quality product. Now, instead of paying for a license to gain access to enterprise features or support, I'm paying to remove ads. From my webserver. Which now has a custom license that I have to read, remember, and figure out how to comply with.

I give up. I'm an individual running 8 little caddy containers on a $5/mo VPS. The cognitive load simply isn't worth it, and I hope you'll reconsider. Otherwise, it's back to cobbling things together with nginx and haproxy. :(
