Provides pre-built React components that wrap LLM inference APIs, enabling developers to embed chat interfaces directly into React applications without building UI from scratch. Components handle message state management, streaming response rendering, and API integration through a declarative component API that abstracts away raw HTTP calls to language model endpoints.
Unique: Provides React-specific component abstractions that integrate directly with the component lifecycle, enabling developers to manage chat state through React hooks and context rather than imperative API calls
vs alternatives: Faster time-to-market than building chat UIs from scratch with raw API calls, but less flexible than lower-level libraries like LangChain.js for complex multi-step reasoning workflows
Abstracts away provider-specific API differences (OpenAI, Anthropic, etc.) behind a unified interface, allowing developers to swap LLM providers or run requests against multiple providers without changing component code. Handles request normalization, response parsing, and error handling across different API schemas and authentication mechanisms.
Unique: Implements provider abstraction at the component level rather than as a separate service, allowing per-component provider configuration and enabling A/B testing different providers within the same React application
vs alternatives: More tightly integrated with React than LiteLLM or LangChain, but less comprehensive in provider coverage and advanced features like structured output validation
Handles server-sent events (SSE) or chunked HTTP responses from LLM APIs, progressively rendering token-by-token output to the UI as it arrives rather than waiting for the complete response. Manages buffering, error recovery during streaming, and automatic UI re-renders on each token chunk using React's state update mechanisms.
Unique: Integrates streaming directly into React component state updates, using custom hooks to manage stream lifecycle and automatically handle cleanup on unmount, rather than requiring manual stream management
vs alternatives: Simpler streaming integration than raw fetch API handling, but less control over buffering strategy and chunk size compared to lower-level stream libraries
Provides a templating system for constructing dynamic prompts with variable substitution, allowing developers to define reusable prompt patterns with placeholders that get filled at runtime from component props or user input. Supports conditional sections and formatting helpers to construct complex prompts without string concatenation.
Unique: Integrates prompt templating directly into React components via props, allowing templates to be defined as component configuration rather than separate files, enabling dynamic template selection based on component state
vs alternatives: More integrated with React component patterns than standalone prompt management tools, but less powerful than full prompt engineering frameworks like Langchain's PromptTemplate for complex multi-step reasoning
Manages conversation history by storing messages in component state or external storage, automatically handling context window limits by truncating or summarizing older messages to fit within LLM token limits. Implements sliding window or summarization strategies to maintain conversation coherence while respecting model constraints.
Unique: Implements context windowing as a React hook that automatically manages message state and respects token limits, allowing developers to treat conversation history as a managed resource rather than manually tracking it
vs alternatives: Simpler than building custom context management, but less sophisticated than LangChain's memory abstractions which support multiple memory types (summary, entity, etc.)
Provides built-in error handling for API failures, network timeouts, and rate limiting, with configurable fallback strategies such as retry logic with exponential backoff, fallback to cached responses, or displaying user-friendly error messages. Distinguishes between recoverable errors (retry) and permanent failures (show error UI).
Unique: Integrates error handling into React component lifecycle, automatically retrying failed requests and updating UI state without requiring manual error handling code in parent components
vs alternatives: More integrated with React than generic HTTP client error handling, but less sophisticated than dedicated resilience libraries like Polly or Resilience4j
Provides TypeScript type definitions and runtime prop validation for all components, ensuring developers catch configuration errors at compile time and preventing runtime crashes from invalid props. Uses TypeScript interfaces and optional runtime schema validation to enforce correct component usage.
Unique: Provides comprehensive TypeScript definitions for all components and props, enabling full IDE autocomplete and type checking without requiring separate type definition files
vs alternatives: Better TypeScript integration than many React component libraries, but less comprehensive than frameworks like Next.js that include built-in type safety for full-stack features
Exposes core functionality as React hooks (useChat, useCompletion, etc.) that can be composed into custom components, allowing developers to build their own UI while reusing the underlying LLM integration logic. Hooks manage state, API calls, and lifecycle independently of UI rendering.
Unique: Exposes all functionality as composable React hooks rather than just pre-built components, allowing developers to build completely custom UIs while reusing the underlying LLM integration and state management logic
vs alternatives: More flexible than pre-built components for custom UIs, but requires more boilerplate code than using components directly; similar approach to Vercel's AI SDK but more React-focused

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 polyfire-js at 26/100.

Search the match graph →© 2026 Unfragile. Stronger through disorder.
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.
