Consumer Messaging Apps

What a messaging app actually needs from its infrastructure

A consumer messaging product lives or dies on details that are invisible until they break: a message delivered out of order, a typing indicator that lags, a reconnect after a network switch that loses the last few seconds of a conversation. All of that comes down to the transport and delivery guarantees underneath the chat UI, not the UI itself.

Relay handles the transport layer end to end — WebSocket and WSS for browsers, QUIC for mobile clients that need to survive a network handoff without dropping a session, and at-least-once delivery as a baseline on every plan — so a messaging product's engineering effort goes into the product experience, not into re-implementing reconnect logic and message ordering from scratch.

What's included

• →Global delivery: 700+ points of presence keep latency low for users wherever they are.
• →End-to-end encryption: mTLS and application-layer encryption keep message content private in transit.
• →Rich media support: the same connection carrying chat events carries media delivery, without a separate CDN integration for basic cases.
• →Scale without a rewrite: the same architecture handles a beta's first thousand users and a later scale to millions, since the Free plan already runs a real two-node cluster with automatic failover.
