Web App
99.9% uptime, E2E encrypted
End-to-end encrypted real-time messaging with WebSockets and client-side crypto. Built for low latency and 99.9% uptime so teams can rely on it for sensitive conversations.
The client needed a private messaging product where only participants could read content—no server-side access to message bodies. It had to feel instant and work reliably for daily use by remote teams.
We implemented E2E encryption in the browser with keys never leaving the client, a Node/WebSocket layer for presence and message routing only, and a React app with offline queuing so messages send as soon as the user is back online.
“We needed something we could trust with confidential discussions. This is it.”
