Only downside seems to be the Performance of tunnels in Containers.
I use them for my personal Website, did a bit of Loadtesting and was able to get significantly more RPS without the CF Tunnel. Might be something on my end tho, not sure.
That's interesting. Cloudflare tunnels do a few things that I expected to to make it perform better in general: obviously TLS termination on CF's side where they likely have faster hardware doing that (at least faster than many customers), then the keep-alive sockets for tunnel<->CF, and I think they use UDP/QUIC for the tunnel<->CF connection[0] which I figure could remove some latency.
