Standard ships every CLIENT component. Professional adds the matching SERVER components. Enterprise adds the high-performance servers (IOCP, EPOLL, HTTP.SYS).
Clients
WebSocket, MQTT, STOMP, AMQP, WAMP and Kafka clients, the Telegram client, the crypto exchange and real-time framework clients, AWS and Azure IoT, the OAuth2 and JWT clients, the UDP and STUN clients, and the OpenSSL transport. HTTP/2, gRPC, the AI and LLM clients and SChannel are not in Standard.
Clients + Servers
Everything in Standard plus the server components: WebSocket Server, WS+HTTP Server, WAMP and WebRTC servers, the SGC, Dataset, Files and Presence protocol servers, the UDP and STUN servers and the DataSnap WebBrokerBridge. It adds the Firewall, LoadBalancer Server, Proxy Server, Rate Limiter, Circuit Breaker and API Key Manager, the WhatsApp Cloud API client and the SChannel transport.
+ Best Performance
Everything in Professional plus the HTTP/2 and gRPC clients, the AI and LLM clients and MCP, the OAuth2 Server, JWT Server and WebAuthn Server with passkeys, the TOTP, LDAP, SAML, OpenID Connect and Mail OAuth2 authentication components, TURN, ICE and RTCPeerConnection, end-to-end encryption, WebPush, multi-node clustering, the OpenAPI Server, and the high-performance server stack: IOCP Indy Server, EPOLL Indy Server, HTTP.SYS Server, and HTTP/2 / HTTP.SYS DataSnap bridges. The high-level AI components (TsgcAIChat, ChatBot, Translator, Assistants, Embeddings, Pinecone) and the OpenAI Realtime client are Windows only. The per-vendor REST clients and MCP are not.

sgcQUIC and sgcWebRTC are separate packages, licensed independently from sgcWebSockets. The columns below show which edition each add-on can be paired with.
| Feature | Standard | Professional | Enterprise |
|---|---|---|---|
| sgcQUIC QUIC (RFC 9000) and HTTP/3 (RFC 9114) client & server components. Separate package, available as an add-on to Enterprise, with full source. | — | — | + |
| sgcWebRTC WebRTC media engine for TsgcRTCPeerConnection: manual SDP signaling, SCTP data channels, Opus/G.711 audio, VP8/H.264 video, DTLS-SRTP encryption. Separate package, available as an add-on to Enterprise, with full source. | — | — | + |
sgcAI, sgcMQ, sgcSocial, sgcAuth, sgcHTTP, sgcREST, sgcHTML and sgcCrypto are standalone packages, not add-ons. Each one bundles the sgcWebSockets Core runtime and is licensed on its own. The columns below say whether an edition already ships the same components. Where a row is ticked you already own them and the package would duplicate what you have. Where it is not ticked, the standalone package is an alternative to upgrading your edition. For sgcSocial, the Telegram client ships in the editions from Standard upward and the WhatsApp client from Professional upward, so the package is aimed at developers without an edition. For sgcAuth, the OAuth2 and JWT clients ship in every edition but WebAuthn is Enterprise-only. For sgcHTTP, the Google Cloud clients ship in every edition but the HTTP/2 and gRPC clients are Enterprise-only. For sgcREST, the OpenAPI client ships in every edition, the REST server from Professional upward, and the OpenAPI server only in Enterprise, so it is aimed at developers who want the REST server or the OpenAPI server without upgrading. For sgcHTML, none of the editions below ships the HTML components. Inside sgcWebSockets they come only with All-Access, so the package is the way to get them on their own.
| Feature | Standard | Professional | Enterprise |
|---|---|---|---|
| sgcAI 15 AI, LLM and MCP components in a self-contained package that bundles the sgcWebSockets Core runtime. The same components ship inside the Enterprise edition, so only Standard and Professional owners have anything to gain from it. | — | — | |
| sgcMQ MQTT 3.1.1 and 5.0, AMQP 0.9.1, AMQP 1.0, Apache Kafka and STOMP clients in a self-contained package that bundles the sgcWebSockets Core runtime. The same components ship inside every edition below, so it is aimed at developers who own none of them. | |||
| sgcSocial WhatsApp Business Cloud API and Telegram TDLib clients in a self-contained package that bundles the sgcWebSockets Core runtime. The Telegram client ships from the Standard edition upward and the WhatsApp client from Professional upward, so it is aimed at developers who own no edition. | — | ||
| sgcAuth OAuth2 client, JWT client, WebAuthn with passkeys, TOTP, LDAP, SAML, OpenID Connect and Mail OAuth2 in a self-contained package that bundles the sgcWebSockets Core runtime. The OAuth2 and JWT clients ship in every edition, the other components only in Enterprise, so it is aimed at developers who want them without upgrading. | — | — | |
| sgcHTTP HTTP/2 client, gRPC client and Google Cloud Pub/Sub, Calendar and FCM clients in a self-contained package that bundles the sgcWebSockets Core runtime. The Google Cloud clients ship in every edition, the HTTP/2 and gRPC clients only in Enterprise, so it is aimed at developers who want HTTP/2 and gRPC without upgrading. | — | — | |
| sgcREST REST server, OpenAPI server and OpenAPI client in a self-contained package that bundles the sgcWebSockets Core runtime. The OpenAPI client ships in every edition, the REST server from Professional upward, and the OpenAPI server only in Enterprise, so it is aimed at developers who want the REST server or the OpenAPI server without upgrading. | — | — | |
| sgcHTML Server-side HTML/UI component library (Bootstrap 5 + htmx) in a self-contained package that bundles the sgcWebSockets Core runtime. None of the editions below ships these components, so the package is aimed at every developer who wants them without All-Access. | — | — | — |
| sgcCrypto Symmetric and asymmetric ciphers, hashing and key management components in a self-contained package that bundles the sgcWebSockets Core runtime. The same components ship inside every edition below, so it is aimed at developers who own none of them. |
Upgrade from Standard to Enterprise without rewriting your client. The core WebSocket API is identical — higher tiers just unlock additional protocol and integration components.
