Core Features

WebSocket Server & Client

• Fully RFC 6455-compliant multithreaded WebSocket server with proven scalability.
• IOCP (I/O Completion Ports) support for high-throughput scenarios, plus the traditional one-thread-per-connection model.
• PerMessage-Deflate compression (RFC 7692) to reduce bandwidth usage.
• Text and binary message support with built-in message queuing.
• Server-Sent Events (SSE) — push notifications over HTTP for lightweight streaming.
• WatchDog and HeartBeat keep connections alive and automatically reconnect on failure.
• HTTP Proxy and SOCKS Proxy support for client connections.
• Serve WebSocket and HTTP traffic on the same port — no extra infrastructure needed.
• Built-in JavaScript libraries for browser-based clients.

Security & Authentication

• SSL/TLS with OpenSSL 1.1.1 and 3.0 support for both server and client.
• SChannel (Windows native TLS) — no external dependencies required on Windows.
• Server and client authentication: Basic, Session, Token, and URL-based.
• OAuth 2.0 authorization for server and client.
• JWT (JSON Web Tokens) — issue, validate, and manage tokens with HS, RS, and ES algorithms.
• End-to-End Encryption (E2EE) protocol for zero-knowledge messaging.
• WebAuthn / FIDO2 server API for passwordless authentication.

HTTP/2

• Full-featured HTTP/2 client with multiplexed streams, header compression, and server push.
• HTTP/2-capable server with alternate service advertisement.

AI & LLM Integrations

Build intelligent applications with native support for the leading AI platforms:

• OpenAI — Chat Completions, Embeddings, Image Generation, and Assistants API. Full streaming support.
• Anthropic Claude — Messages API with streaming, tool use, and vision capabilities.
• MCP (Model Context Protocol) Server — Host your own MCP server to expose tools, resources, and prompts to AI agents. Supports HTTP and Streamable HTTP transports with API key and custom header authentication.

Messaging Protocols

Enterprise-grade messaging with support for the most widely adopted protocols:

• MQTT 3.1.1 & 5.0 — Lightweight pub/sub messaging for IoT and mobile. Full QoS support, Last Will & Testament, and MQTT 5.0 properties.
• AMQP 0-9-1 & AMQP 1.0 — Advanced message queuing for enterprise integration.
• STOMP — Simple text-based messaging with dedicated ActiveMQ and RabbitMQ connectors.
• WAMP & WAMP2 — Web Application Messaging Protocol for RPC and pub/sub patterns.
• Socket.IO — Real-time bidirectional event-based communication.
• SignalR & SignalR Core — Microsoft's real-time framework with bearer token and cookie authentication.

Crypto & Financial Exchange APIs

Connect to 20+ cryptocurrency and financial exchanges with both REST and WebSocket APIs — real-time market data, order management, and account streaming:

IoT & Cloud

Seamlessly connect devices to the leading cloud IoT platforms:

• AWS IoT Core — MQTT-based device communication with certificate, custom authentication, and Signature V4 support.
• Azure IoT Hub — Device-to-cloud messaging with certificate and SAS token authentication.
• Google Cloud Platform — Calendar API, Firebase Cloud Messaging (FCM), and Pub/Sub integration with JWT and OAuth 2.0.
• AWS SQS — Simple Queue Service for decoupled messaging architectures.

WebRTC & Peer-to-Peer

Build real-time audio, video, and data channel applications:

• STUN client and server — NAT traversal with short-term and long-term credential authentication.
• TURN client and server — relay-based connectivity with allocation management, channel binding, and auto-refresh.
• WebRTC signaling server — ready-to-use signaling for peer-to-peer connections.
• AppRTC — Google-compatible WebRTC server with configurable media constraints.
• RTCMultiConnection — multi-user video conferencing server with customizable video resolution options.

Social & Messaging Platforms

• Telegram — Full-featured Telegram client via TDLib: send and receive text, photos, videos, documents, inline keyboards, and payments.
• WhatsApp Business — Cloud API client with webhook support for automated messaging.
• Discord — Bot integration via WebSocket gateway.

Additional Protocols & Features

• WebPush — Send push notifications to browsers with VAPID authentication (PEM and DER key formats).
• Files Transfer Protocol — Reliable file transfer over WebSocket with QoS and synchronization.
• Presence Protocol — Track online/offline user status with acknowledgment support.
• Broker & Load Balancer — Distribute WebSocket connections across multiple server instances.
• RCON — Remote console protocol for game server administration.
• HTTP Forward — Forward HTTP requests through WebSocket server infrastructure.

QuickStart

WebSocket Server

// 1. Create a new Windows Forms Application
// 2. Drop a TsgcWebSocketServer onto the Form
// 3. Handle the OnMessage event:

private void OnMessage(TsgcWSConnection Connection, string Text)
{
    MessageBox.Show("Message Received: " + Text);
}

// 4. Start the server:
TsgcWebSocketServer1.Active = true;

WebSocket Client

// 1. Create a new Windows Forms Application
// 2. Drop a TsgcWebSocketClient onto the Form
// 3. Configure Host and Port properties

// Connect:
TsgcWebSocketClient1.Active = true;

// Send a message:
TsgcWebSocketClient1.WriteData("Hello Server!");
