APIs That Push, Not Just Respond in Altrincham

“Some products need data the moment it changes — live dashboards, chat and collaboration, presence, order or delivery tracking, instant notifications in Altrincham. Request/response REST can't do that well; polling is wasteful and laggy. JW Digital builds realtime APIs over WebSocket and Server-Sent Events with the parts that make them reliable in production: authentication, reconnection, fan-out scaling and backpressure. This is distinct from custom (REST) API development and from event-driven architecture, which orchestrates async work between internal services.”

— Janusz Wozniak

The Right Tool for Live, Not the Wrong Tool Faster in Altrincham

WebSocket/SSE transport built for production scale in Altrincham

Teams often try to fake realtime by polling a REST endpoint more aggressively — adding load and latency without ever feeling live. This service builds the correct transport for client-facing live data: persistent connections, authenticated and reconnecting cleanly, scaled to many concurrent clients with backpressure so a slow consumer can't take the system down. Where the realtime need is internal service-to-service async, event-driven architecture is the better fit; for standard CRUD, custom API development.

Why you need APIs That Push, Not Just Respond in Altrincham

The bottom line

A realtime API isn't a fast REST API — it's a different system with stateful connections, reconnection logic, ordering and delivery guarantees, and a scaling model where thousands of clients hold open connections at once. Done naively it works in a demo and falls over under real load or flaky mobile networks. in Altrincham Built deliberately, realtime becomes a dependable product capability — live collaboration, tracking and notifications that genuinely feel instant — instead of a fragile feature that breaks at scale.
