Well. I have a one small project that did the exact thing that you mentioned above.

What is your preferred #nostr web client that can show single relay data without login?
My favorites are Coracle, Nostrudel, Nostrrr, and Njump. Thanks to

I like how Coracle can show single relay data without login, and it feels like surfing "global feed" for certain relay

The only downside is it doesn't seems support url parameters yet.
Nostrudel on the other hand has already support url parameters

And if we like simplicity, nostrrr.com and njump.me are good choices because they only give text without rendering many graphics.

Are there any web clients beside 4 of them who can display single relay without login? What is your favorites?

Really nice. It also support url parameters and render graphic 👀

Code is quite small.
There may be things that does not works well. But as of now it looks good.
I think it looks already good with simple style and a bit of graphic rendering (with optional image proxy setting). Maybe, it just need to have simple button to redirect to other clients like njump has done.
