and w3m has w3m-img if you want to get just one step more graphical while still being fundamentally a tui (it does terminal/character cell layout, then uses the WINDOWID to stuff images on the terminal screen. Probably the kind of thing wayland doesn't allow? :-)
w3m also supports image display through the sixel, kitty, and mlterm image protocols; these should also work on wayland with terminal emulators that support them (i.e. almost any terminal except vte or alacritty).
Maybe I'm in the minority here, but the GitHub readme seems to convey what the project actually is, with written text. On the website I just see a bunch of fancy images and marketing gabble, but it doesn't actually say what Neonmodem is on it.
all i see on the website is a download link and an animated screenshot, both of which are also on the github page along with a lot of other information. i even opened it up in incognito mode to see if one of my extensions was blocking stuff, but no, it really does look like a superminimal site to me.
WeeChat[0] (or any IRC client, really, but weechat is nice) with Bitlbee[1] supports a metric assload of services, albeit by pretending they're IRC (which does work - I spent years in weechat/irssi with bitlbee talking to various people on disparate services.)
Or if you're just after Telegram/WhatsApp, nchat[2] is ok (I can vouch for the Telegram half only.)
It's a text-based web browser.
It's possible you already have Lynx installed, and it'd give similar results (but is general purpose for any website)
