The problem I kept running into

Every "private" messenger I found had the same tradeoffs:

Signal → needs your phone number. That's an identity anchor.

Telegram → not E2E by default. Server-side messages.

WhatsApp → Meta. Enough said.

Matrix/Element → self-host complexity, still needs an account.

Briar → great, but mobile-only and requires install.

I wanted something where neither party has to prove who they are to anyone — not to a server, not to a phone carrier, not to an app store. Just open a browser, agree on a channel ID and a PIN, and talk. That's it.

So I built it.
