I want to make it dead-easy for others to chat with me. I want a browser-based, FLOSS, E2EE chat solution that doesn't require the other party to log in. Does that exist? (lemmy.ml)

Here's my problem: every F(L)OSS and E2EE solution that I know of requires other people to download an app or log in.

I want to reduce the friction for others to communicate for me. I want to give a business card with a URL where people can go and immediately send messages to my Matrix or my email or something, and they don't need to log in at all.

They just open their browser, go to snek_boi.io or whatever and a chat appears.

A couple of years ago, I was suggested Cactus Comments. I suppose that works, but I was wondering if there are other solutions. I was wondering if now there was an even easier solution for my purposes.

i'm trying to understand your exact scenario.

but in general, the problem is where do you get your original key, or original hash to verify from? if they are both coming from the server, along with the code which processes them, then if the server is compromised, so are you.

thankfully browsers give alot of crypto API lately (as discussed in your link)

but you still need at minimum a secure key, a hash and trusted code to verify the code the server serves you. there are ofc solutions to this problem, but if the server is unstrusted, you absolutely can't get it from them, which means you have to get it from somewhere else (that you trust).
