WebSockets for Developers

WebSockets for developers

A practical guide to WebSockets, managed realtime infrastructure, and the application concerns that sit above a persistent connection.

What WebSockets are for

A WebSocket keeps a connection open so a client and server can send messages to each other without opening a new HTTP request for every message. That bidirectional shape can fit chat, collaboration, live dashboards, notifications, commerce updates, multiplayer experiences, and agent interfaces.

The connection is a transport. Your application still needs to decide what each message means, which data is authoritative, which participants can see it, and what the client should do when the connection is interrupted.

Choose a transport for the interaction

Polling

Polling repeats ordinary HTTP requests on a schedule. It is straightforward when updates can arrive at intervals, but each client waits for its next request to learn about a change.

Server-Sent Events

Server-Sent Events provide a one-way stream from server to client. They can fit server updates when the client sends actions separately through HTTP.

WebSockets

WebSockets allow messages in both directions over a persistent connection. They can fit interactions where clients and servers both need to send events while work is in progress.

What to evaluate in managed WebSocket infrastructure

Running a connection service involves decisions beyond opening a socket. When comparing a managed service with a system you operate yourself, check the actual contract for each concern:

  • How clients and services authenticate, and how connection identity is handled.
  • What reconnect behavior is available, and whether missed events can be recovered.
  • How messages are routed to participants, and what ordering or delivery guarantees apply.
  • How the service behaves under bursts, slow consumers, and payload limits.
  • What connection lifecycle, traffic, and service health information you can inspect.
  • How regions, capacity limits, throughput, and pricing fit your workload.

These are questions to verify in a provider's current documentation. They are not interchangeable guarantees, and they should not be inferred from the phrase “managed WebSockets.”

Where Lynta fits

Lynta is realtime infrastructure for applications and AI agents. Its product model adds three concepts to the connection layer: State syncs backend changes to connected clients, Channels carry ephemeral bidirectional events, and Tasks coordinate live work between people and agents.

Your backend and database remain authoritative. Lynta makes changes live; it does not become your database or execute your agents.

Lynta's public site does not currently publish a protocol-level API reference or provider guarantees. Use this page to understand the product model, not as an implementation contract.
