Announcements and engineering notes from the MeshWhisper project.https://meshwhisper.org/https://meshwhisper.org/blog/the-flake-was-a-bug/https://meshwhisper.org/blog/the-flake-was-a-bug/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.Tue, 16 Jun 2026 15:00:00 GMThttps://meshwhisper.org/blog/dns-free-relay-location/https://meshwhisper.org/blog/dns-free-relay-location/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.Tue, 16 Jun 2026 13:00:00 GMThttps://meshwhisper.org/blog/messaging-like-email/https://meshwhisper.org/blog/messaging-like-email/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.Mon, 15 Jun 2026 10:00:00 GMThttps://meshwhisper.org/blog/what-the-relay-sees/https://meshwhisper.org/blog/what-the-relay-sees/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.Sun, 14 Jun 2026 10:00:00 GMThttps://meshwhisper.org/blog/prudence-grew-up/https://meshwhisper.org/blog/prudence-grew-up/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.Sat, 13 Jun 2026 10:00:00 GMThttps://meshwhisper.org/blog/meshwhisper-0-3/https://meshwhisper.org/blog/meshwhisper-0-3/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.Fri, 12 Jun 2026 13:00:00 GMThttps://meshwhisper.org/blog/who-its-for/https://meshwhisper.org/blog/who-its-for/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.Fri, 12 Jun 2026 12:00:00 GMThttps://meshwhisper.org/blog/what-it-does/https://meshwhisper.org/blog/what-it-does/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.Fri, 12 Jun 2026 11:00:00 GMThttps://meshwhisper.org/blog/the-story/https://meshwhisper.org/blog/the-story/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.Fri, 12 Jun 2026 10:00:00 GMThttps://meshwhisper.org/blog/what-is-meshwhisper/https://meshwhisper.org/blog/what-is-meshwhisper/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.Fri, 12 Jun 2026 09:00:00 GMT
