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…
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…
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…
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…
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…
Streaming LLM Responses in Delphi: Token-by-Token with Server-Sent Events
Stream LLM replies token by token in Delphi: assign OnHTTPAPISSE, call the streaming method, append each delta to a Memo. Same pattern for every provider…
OpenAI vs Anthropic vs Gemini in Delphi: Which AI API Should You Use?
OpenAI, Anthropic Claude or Google Gemini for your Delphi app? How each looks in code, what each is good at, and why the choice is reversible…
RAG in Delphi: Ground an LLM in Your Own Documents
Stop the model from guessing. Embed your own documents, store the vectors, retrieve the closest chunks per question, and let the LLM answer from your data in Delphi…
Google Cloud Storage over gRPC in Delphi
A practical guide to the typed Google Cloud Storage gRPC client in sgcWebSockets Enterprise: how it runs over the HTTP/2 transport, how service-account JWT authentication works, and Delphi examples for listing buckets, creating a bucket and listing objects…
Build an AI Agent in Delphi: Function Calling and MCP Tool Use
An AI agent is an LLM that calls your own code through tools, in a loop. Two ways to build one in Delphi: provider function calling and the MCP open standard…
Build an AI Chatbot in Delphi: Conversation Memory and Streaming
A one-shot completion forgets everything. A chatbot remembers. How to keep conversation context across turns in Delphi, and stream a live reply…
Google Cloud Natural Language over gRPC in Delphi
A practical walkthrough of calling Google Cloud Natural Language from Delphi over gRPC: how the typed Natural Language client rides the sgcWebSockets HTTP/2 transport, how service-account authentication works, and Delphi examples that analyze sentiment, extract entities and classify text…
sgcIndy 2026.6: Server Security Hardening for TLS, TCP and HTTP
sgcIndy 2026.6 brings opt-in security hardening to its server stack: strict TLS certificate verification, CRIME and renegotiation mitigations, server cipher preference, Slowloris protection with a total read deadline, HTTP body and header size limits, request-smuggling rejection, plus ML-KEM-768 post-quantum primitives…
Hardening the HTTP Server in sgcWebSockets
The HTTP servers now block path traversal in static file serving, bound the request body, reject smuggling-style requests, defend HTTP/2 against Rapid Reset, and sanitize response headers…
Google Cloud Vision over gRPC in Delphi
How to call Google Cloud Vision from Delphi over gRPC with sgcWebSockets: a typed Vision client on TsgcGRPCClient that runs label, text (OCR), face and landmark detection over HTTP/2, with service-account JWT auth and a ready-to-run demo…
Google Cloud Translation over gRPC in Delphi
