Onyx implements a pluggable connector framework that abstracts 20+ data sources (Slack, Google Drive, Confluence, GitHub, etc.) into a unified document ingestion pipeline. Each connector implements a standardized lifecycle (credential validation, document fetching, chunking, metadata extraction) and feeds into a Celery-based background task queue that coordinates with Vespa for full-text and semantic indexing. The system maintains connector state, handles incremental syncs, and manages credential encryption via a centralized credential store.
Unique: Implements a standardized connector lifecycle pattern with Celery-based async coordination and Vespa dual-indexing (full-text + semantic), enabling incremental syncs and credential management without re-indexing entire corpora. Uses Redis for distributed task coordination and maintains connector state in PostgreSQL for resumable operations.
vs alternatives: More flexible than Langchain's document loaders because connectors are first-class entities with state management, retry logic, and incremental sync support; more enterprise-ready than simple vector DB connectors because it handles credential rotation and multi-tenant isolation.
Onyx implements a RAG pipeline that retrieves relevant documents from Vespa using hybrid search (BM25 + semantic similarity), ranks results using LLM-based relevance scoring, and injects retrieved context into the LLM prompt with explicit citation metadata. The system tracks which documents contributed to each response, enables users to click through to source documents, and supports configurable retrieval strategies (dense-only, sparse-only, or hybrid). Retrieved chunks maintain document ID, source connector, and chunk position for precise citation.
Unique: Combines Vespa's hybrid search (BM25 + semantic) with LLM-based re-ranking and maintains explicit citation metadata (document ID, chunk position, source connector) throughout the pipeline, enabling precise source attribution and click-through verification. Supports configurable retrieval strategies per-assistant without re-indexing.
vs alternatives: More transparent than black-box RAG systems because citations are first-class data with full provenance; more flexible than simple vector search because hybrid scoring reduces hallucination from semantic-only retrieval and supports multiple ranking strategies.
Onyx provides a Next.js-based chat UI that streams LLM responses in real-time using Server-Sent Events (SSE), displaying tokens as they arrive. The frontend maintains local state for conversations, messages, and UI elements (input field, citation popups, research progress) using React hooks and TypeScript. The UI supports markdown rendering, code syntax highlighting, citation links, and responsive design. Real-time updates are coordinated via WebSocket or polling, and the frontend implements optimistic updates for better perceived latency.
Unique: Implements real-time response streaming via Server-Sent Events with optimistic UI updates and citation rendering. Uses React hooks for state management and supports markdown/code rendering with syntax highlighting, enabling responsive chat UX with minimal latency perception.
vs alternatives: More responsive than polling-based chat because SSE streaming delivers tokens immediately; more feature-rich than basic chat UIs because it supports citations, markdown, and code highlighting.
Onyx implements a Model Context Protocol (MCP) server that exposes Onyx capabilities (search, retrieval, assistant management) to external LLM clients. External applications can call Onyx tools via MCP, enabling workflows where an external LLM orchestrates Onyx operations. The MCP server is implemented as a separate service that communicates with the main Onyx API, and supports standard MCP tool schemas for function calling. This enables integration with other AI systems and agents that support MCP.
Unique: Implements a Model Context Protocol server that exposes Onyx capabilities (search, retrieval, chat) to external LLM clients, enabling multi-agent workflows where Onyx is orchestrated by external agents. Supports standard MCP tool schemas for function calling.
vs alternatives: More interoperable than proprietary APIs because MCP is a standard protocol; more flexible than single-agent systems because external agents can orchestrate Onyx operations.
Onyx provides an embeddable chat widget that can be deployed on third-party websites via a simple script tag. The widget communicates with the Onyx backend via CORS-enabled API calls and maintains conversation state in the browser. The widget is customizable (colors, position, initial message) via configuration parameters, and supports authentication via JWT tokens or API keys. The widget is built with vanilla JavaScript (no framework dependencies) to minimize bundle size and compatibility issues.
Unique: Provides a lightweight embeddable chat widget built with vanilla JavaScript (no framework dependencies) that communicates with Onyx backend via CORS-enabled APIs. Supports customization via configuration parameters and authentication via JWT or API keys.
vs alternatives: Lighter than framework-based widgets because it uses vanilla JavaScript; more flexible than iframe-based embedding because it communicates directly with the Onyx API.
Onyx provides a desktop application (built with Electron or similar) that can run locally or connect to a remote Onyx instance. The desktop app maintains local conversation history and can work offline with cached documents. It supports keyboard shortcuts, system tray integration, and native file dialogs for document upload. The app is built with the same frontend code as the web UI, enabling code reuse and consistent UX across platforms.
Unique: Provides a native desktop application with local-first architecture supporting offline conversations and cached documents. Reuses frontend code from web UI while adding native integrations (clipboard, file dialogs, system tray).
vs alternatives: More responsive than web app because it runs natively; more capable than web app because it supports system integration and offline mode.
Onyx provides a command-line interface (onyx-cli) for programmatic access to Onyx capabilities: searching documents, creating conversations, managing assistants, and uploading documents. The CLI is built with Python and uses the Onyx API, enabling automation workflows and integration with shell scripts. The CLI supports output formatting (JSON, CSV, table) for easy parsing, and authentication via API keys or environment variables.
Unique: Provides a Python-based CLI that exposes Onyx capabilities for automation and scripting. Supports multiple output formats (JSON, CSV, table) and integrates with shell scripts and CI/CD pipelines via API key authentication.
vs alternatives: More scriptable than web UI because it supports programmatic access; more flexible than REST API because it provides high-level commands for common operations.
Onyx provides a Chrome extension that enables searching Onyx documents and chatting with Onyx directly from the browser. The extension adds a sidebar to the browser that communicates with the Onyx backend, allowing users to search without leaving their current page. The extension supports authentication via OAuth or API keys, and maintains conversation state across browser sessions. The extension can be configured to search specific assistants or document collections.
Unique: Provides a Chrome extension that integrates Onyx search and chat into the browser sidebar, enabling quick access to documents without leaving the current page. Supports OAuth and API key authentication with conversation persistence across sessions.
vs alternatives: More convenient than opening Onyx in a separate tab because it maintains context in the sidebar; more integrated than web UI because it works alongside other browser applications.

Crawls 11+ heterogeneous platforms (Zhihu, Weibo, Bilibili, Twitter, Reddit, HackerNews, etc.) and RSS feeds using platform-specific scrapers, normalizes disparate data schemas into a unified NewsItem model, and deduplicates content across sources using fuzzy title matching and URL canonicalization. The system maintains platform-specific metadata (rank, heat value, engagement metrics) while presenting a single normalized feed, enabling cross-platform trend detection that would be invisible within individual platform silos.
Unique: Implements platform-specific crawler modules with unified NewsItem schema and fuzzy deduplication across 11+ heterogeneous sources (Chinese + international), rather than relying on single-platform APIs or generic RSS parsing. Maintains platform-specific metadata (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) for weighted hotspot scoring.
vs alternatives: Covers more platforms (especially Chinese social media) with deeper metadata extraction than generic RSS aggregators, and provides unified deduplication across sources unlike single-platform monitoring tools.
Implements a multi-stage filtering pipeline that matches news items against user-defined keywords using regex patterns, required word lists, and excluded word lists. The system applies frequency-based scoring (keyword occurrence count) combined with platform hotspot weights to rank filtered results. Configuration is stored in frequency_words.txt with support for regex patterns, AND/OR/NOT boolean operators, and per-keyword weighting. Filtering occurs at collection time (reducing storage) and again at report generation time (enabling dynamic reconfiguration without re-crawling).
Unique: Combines regex pattern matching with frequency-based scoring and platform hotspot weighting (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) in a two-stage pipeline (collection-time and report-time filtering). Supports dynamic reconfiguration without re-crawling by applying filters at report generation.
TrendRadar scores higher at 58/100 vs onyx at 37/100.

vs alternatives: More flexible than simple keyword matching (supports regex and boolean logic) and more efficient than semantic filtering (no LLM overhead), making it suitable for real-time filtering at scale.
Detects newly emerged topics by comparing current crawl results against historical data stored in the system. Topics are marked as 🆕 (new) if they appear for the first time in the current crawl or if their hotspot rank increased significantly compared to previous crawls. The system tracks topic emergence velocity (how quickly a topic rises in rankings) and flags topics with unusual acceleration. New topic detection is performed at report generation time, enabling dynamic detection without re-crawling. The system maintains a historical hotspot index for comparison.
Unique: Detects new topics by comparing current hotspot rankings against historical data, marking topics with significant rank increases as 🆕. Tracks emergence velocity to distinguish breaking news from sustained trends.
vs alternatives: More efficient than semantic similarity detection (no LLM overhead) and more accurate than simple first-appearance detection (accounts for re-emerging topics), but requires historical baseline data.
Provides a web-based UI for editing TrendRadar configuration files (config.yaml, frequency_words.txt, timeline.yaml) with real-time validation and preview. The editor supports: (1) syntax highlighting for YAML and regex, (2) validation of keyword patterns (regex compilation check), (3) preview of filtered results based on current keyword configuration, (4) drag-and-drop channel configuration, (5) schedule preview (shows next 10 execution times). Changes are validated before saving, preventing configuration errors. The editor is optional; users can edit config files directly.
Unique: Provides web-based configuration editor with real-time validation, regex preview, and schedule visualization. Enables non-technical users to configure TrendRadar without editing YAML files.
vs alternatives: More user-friendly than manual YAML editing and provides validation feedback, but adds operational complexity compared to file-based configuration.
Integrates LiteLLM to provide vendor-agnostic AI analysis and summarization of filtered news items. Users configure their preferred LLM provider (OpenAI, Anthropic, Ollama, local models, etc.) once in config.yaml, and the system automatically routes analysis requests to that provider. The AI analysis capability includes: (1) automated summarization of long articles into key points, (2) sentiment analysis (positive/negative/neutral), (3) trend prediction based on historical patterns, and (4) custom analysis prompts. Analysis results are cached to avoid redundant API calls and can be pushed directly to notification channels.
Unique: Uses LiteLLM abstraction layer to support any LLM provider (OpenAI, Anthropic, Ollama, local models) with single configuration, enabling provider switching without code changes. Caches analysis results to reduce redundant API calls and costs.
vs alternatives: More flexible than hardcoded OpenAI integration (supports any LiteLLM provider) and cheaper than dedicated sentiment analysis APIs (can use local models), but slower than rule-based sentiment analysis.
Leverages LiteLLM to translate news content from source languages (primarily Chinese) to target languages (English, etc.) on-demand. The system detects source language automatically (via langdetect or similar), caches translations to avoid re-translating identical content, and batches translation requests to reduce API calls. Translations are stored alongside original content, enabling bilingual reports and multi-language notification delivery. Translation can be triggered at collection time (all news) or report time (only filtered news).
Unique: Implements provider-agnostic translation via LiteLLM with automatic language detection, content-based caching, and batch request optimization. Stores translations alongside originals for bilingual report generation.
vs alternatives: More flexible than dedicated translation APIs (supports any LiteLLM provider) and cheaper than commercial translation services when using local models, but slower than specialized translation APIs.
Implements a notification abstraction layer supporting 9+ delivery channels (WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc.). Each channel has a provider-specific formatter that converts normalized news items into channel-appropriate messages (e.g., WeChat card format, Telegram markdown, email HTML). The system batches notifications atomically—all news items for a report are sent as a single batch to each channel, ensuring consistency and reducing API calls. Message formatting respects channel constraints (character limits, attachment limits, etc.) and supports templating for customization.
Unique: Implements atomic message batching across 9+ heterogeneous channels with provider-specific formatters and constraint-aware truncation. Single configuration enables simultaneous delivery to WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc. without code changes.
vs alternatives: Supports more channels (especially Chinese platforms like WeWork, Feishu) than generic notification services, and batching reduces API calls and spam compared to per-item notifications.
Exposes TrendRadar's data and analysis capabilities as an MCP server, enabling AI agents and LLM applications to query trends, perform analysis, and generate insights through natural language. The MCP server implements tools for: (1) querying filtered news by keyword/date/platform, (2) retrieving trend statistics and hotspot rankings, (3) running custom analysis on news subsets, (4) generating reports in various formats. Clients (Claude, other LLM agents) can invoke these tools via MCP protocol, enabling conversational exploration of trends without direct database access. The server maintains state across multiple requests, allowing multi-turn conversations about trends.
Unique: Implements full MCP server exposing trend data and analysis tools to LLM agents, enabling conversational queries and multi-turn analysis workflows. Maintains state across requests and supports complex tool invocations (filtering, analysis, report generation).
vs alternatives: Enables conversational access to trends (vs. API-only access) and integrates with LLM agent workflows (vs. standalone tools), but adds operational complexity compared to simple REST APIs.
