A delete-and-re-add test failed about one run in eight under load. The tempting fix was a bigger timeout. The real fix was a bug: a single stray packet could make the SDK re-handshake — and silently destroy — a perfectly healthy session.
MeshWhisper relays now locate and reach each other by cryptographic key — no DNS anywhere in the routing path. Through NAT, with onion-routed hops, even when both ends are firewalled. The last bit of centralization in the mesh, removed.
Every messenger is a walled garden: WhatsApp users can't message Signal users, and that's by design, not accident. But MeshWhisper's relay can't even tell which app a packet belongs to — so the walls were never load-bearing. We tore one down. Any app, any operator, anyone-to-anyone, end-to-end encrypted. Like email, except private.
The whole pitch is that the relay can't read your messages. That's a claim. So we added a button that puts your plaintext next to the exact encrypted blob the relay actually receives — same screen, no trust required. Tap a message, see the ciphertext.
Prudence could already send end-to-end encrypted messages. That's not the same as being an app you'd leave open all day. This is the unglamorous week of drafts, search, delete, export-your-data, and adding a friend by pointing your camera at their phone — the work that turns a proof into a product.
Two devices on the same network now deliver messages peer-to-peer. Kill the relay, pull the internet — the conversation carries on, encrypted, like nothing happened. Plus open federation and the rest of a busy two months.
Where structural can't-read-it messaging actually matters: regulated industries, isolated networks, machines talking to machines, and AI agents that need to prove who they're talking to.
The capabilities, honestly labelled: what's production, what's shipped-but-young, and what's a designed promise. No roadmap items wearing a trenchcoat pretending to be features.
The origin story: two lads, one late-night conversation, two PRDs written simultaneously by accident, and a working prototype before anyone had the sense to go to bed.
The whole idea in one sitting: end-to-end encrypted messaging for any app, through infrastructure that couldn't read your messages if it wanted to. Which it doesn't. It's a pipe.
