sgcWebSockets keeps a bounded per-channel message history with offsets, so a client that drops its connection automatically replays the messages it missed on reconnect, opt-in, with Delphi and .NET examples…
sgcWebSockets Clustering — Scale WebSocket Servers Across Multiple Nodes
TsgcWSCluster scales sgcWebSockets across multiple server nodes, a publish or Presence event on one node reaches subscribers on any other node, via a zero-infrastructure mesh backplane or Redis, with Delphi and .NET examples…
sgcHTML vs UniGUI, TMS WEB Core and IntraWeb: Choosing Your Delphi Web Framework
Detailed comparison of Delphi web UI frameworks: IntraWeb, UniGUI, TMS WEB Core, TMS XData and sgcHTML — architecture, deployment, learning curve and real-time capability…
Building a Real-Time ERP Dashboard with sgcHTML and Delphi
Step-by-step guide to a live ERP dashboard in Delphi using sgcHTML: KPI stat cards, revenue charts, a paginated invoice table, a Kanban board and real-time WebSocket push updates…
sgcHTML: Build Modern Web UIs from Delphi Without Writing JavaScript
sgcHTML gives Delphi, C++ Builder and .NET developers 60+ server-side HTML components that render Bootstrap 5 markup and stay interactive through htmx — no JavaScript required…
sgcWebSockets 2026.6: gRPC, OpenAPI Server, Kafka and Native TLS
sgcWebSockets 2026.6 adds a native gRPC client, a standalone OpenAPI 3 server, an Apache Kafka client, native Android and Apple TLS (no OpenSSL), firewall bot detection, an MCP stdio transport, post-quantum crypto and hardened WebSocket and HTTP servers…
sgcSign Server: Self-Hosted Code-Signing and Document-Signing over REST
A self-hosted REST signing server in sgcSign 2026.6: sign executables, PDFs and XML documents from CI without putting the private key on every build agent, with an admin console, an audit log and pluggable HSM and cloud-KMS providers…
Native Android TLS in sgcWebSockets: No OpenSSL to Deploy
A new native Android TLS backend lets your apps connect over TLS using Android's own SSLEngine, so the APK ships no OpenSSL .so files. Switching is a one-line change to TLSOptions.IOHandler…
Native Apple TLS in sgcWebSockets: TLS 1.3 on iOS and macOS, No OpenSSL
A new native Apple TLS backend lets your iOS and macOS apps connect over TLS using the operating system's own stack, so there is no OpenSSL .dylib to deploy and you get TLS 1.3 through Network.framework…
Google Vertex AI over gRPC in Delphi
sgcWebSockets Enterprise ships a typed Vertex AI gRPC client on TsgcGRPCClient. Call Gemini models from Delphi over HTTP/2, authenticate with a service account, build a generateContent request from content parts and read the candidates back…
Streaming Large Files from the sgcWebSockets HTTP Server
Serving files from DocumentRoot used to load the whole file into memory per connection, so 100 downloads of a 1 GB file needed about 100 GB of RAM. Files now stream from disk and memory stays flat…
Google BigQuery over gRPC in Delphi
A practical guide to reading Google BigQuery tables from Delphi over the gRPC Storage Read API: how the typed BigQuery client on TsgcGRPCClient runs over HTTP/2, authenticates with a service account, creates a read session and server-streams rows in Avro or Arrow…
