It includes tools for discovering cluster nodes and managing indices to maintain connection stability and organize data storage. The client covers a broad range of operations, including document lifecycle management for CRUD actions, search query execution,

PostgREST is a standalone web server that automatically transforms a PostgreSQL database into a RESTful API. It serves as an API gateway that translates HTTP requests into SQL queries, mapping the database schema directly to endpoints without the need for manual route definitions. The system utilizes a JWT authentication layer to validate user identities and map incoming web requests to specific database roles. This allows the server to delegate authorization and permission enforcement to the internal PostgreSQL role system. It includes a generator for OpenAPI specifications to provide stand

n8n-skills is a collection of technical guides and architectural frameworks for designing, building, and deploying automation workflows and AI agents within n8n. It provides a structured approach to creating autonomous agents by combining large language model chains with memory systems and custom toolsets.

It emphasizes the use of specific architectural patterns to manage webhooks, APIs, and binary data handling

This project is a web-based user interface for interacting with large language models, featuring streaming responses and persistent conversation history. It functions as an orchestration gateway that directs user prompts to specific language models and acts as a Model Context Protocol client to execute external tools and incorporate live data into conversations. The application includes a routing layer that analyzes input signals and tool requirements to dynamically direct messages to the most appropriate specialized model. It also provides customization settings for brand identity, allowing

DeepChat is a desktop application that connects to multiple cloud and local AI model providers through a single unified chat interface, while also integrating external ACP-compatible coding and task agents as selectable models. It manages local AI agent sessions with project folders, permission modes, and resumable context for long-running tasks, and connects external tools and data sources via the Model Context Protocol using StreamableHTTP, SSE, or Stdio transports. The application distinguishes itself by supporting remote desktop session control, binding messaging app channels to sessions

Sonic is a high-performance, lightweight search backend designed to provide real-time full-text search and autocomplete capabilities for applications. It functions as a persistent indexing server that maps text terms to object identifiers, allowing developers to integrate rapid search functionality without storing raw document content directly within the search engine. The system distinguishes itself through a specialized graph-based index that enables real-time word prediction and typo correction. Communication is handled via a custom, low-latency binary protocol over raw TCP sockets, which

Zombodb is a database extension and relational data indexer that integrates PostgreSQL with Elasticsearch. It provides a SQL search interface, allowing users to execute complex search queries and aggregations using standard SQL functions and syntax instead of native JSON APIs.
