Good question! I have nothing against Traefik. I just haven't used it as much, whereas with Envoy I've both used it and contributed to it a little bit too.

Makes sense. I see nothing wrong with any of them, I just never heard of Envoy and I used mostly Traefik.

I even used its experimental http3 support in v2, and now it's stable in v3. As stable as it can get I guess.
