LatteStream

LatteStream is a developer-first WebSocket infrastructure service that delivers enterprise-grade real-time messaging at a fraction of traditional costs. Built by engineers tired of overpaying for basic infrastructure, we offer sustainable, transparent pricing that scales with your business.

Key Features:

• $3 per 100 concurrent connections - No hidden fees, no message limits, no bandwidth charges
• Unlimited messaging - Send billions of messages without worrying about overages.
• Rust-powered performance - Memory-safe, blazing fast infrastructure with consistent low-latency delivery
• Enterprise security - TLS 1.3, encrypted connections, secure token authentication, and isolated tenant infrastructure
• Production-ready - Raft consensus for reliability, automatic failover, and zero-downtime deployments
• Simple integration - WebSocket API SDKs, get started in minutes
• No vendor lock-in - Standard WebSocket protocol means you're never trapped
• Private and presence channels

Why LatteStream? While Pusher charges $49/month for just 500 connections and 1M messages, and Ably starts at $29/month baseline with strict limits and complex pricing based on usage, LatteStream gives you 100 connections for $3 with unlimited messaging. We achieve this through efficient engineering, not VC subsidies which means our pricing is sustainable long-term.

Some use cases include real-time collaborative apps, live dashboards and monitoring, chat and messaging applications, multiplayer games, IoT device communication, live sports and financial data streaming, notifications, and any other case that needs real-time server-client, client-client communication.

Our infrastructure is designed around the principle that WebSocket hosting should be boring, reliable, and affordable. No emergency maintenance, no surprise bills, just solid infrastructure that works. Start at $3/month and scale confidently knowing your costs will remain predictable and fair.
