AstrBot implements a platform adapter abstraction layer that normalizes incoming messages from Discord, Telegram, QQ, and web chat into a unified internal message format, then routes responses back through platform-specific adapters. The system uses a connection mode abstraction supporting both webhook and polling patterns, with message component transformation that converts platform-native rich content (embeds, reactions, files) into a standardized AST-like structure for processing. This enables a single agent pipeline to serve heterogeneous chat platforms without duplicating business logic.
Unique: Uses a two-stage transformation pipeline (platform → canonical → platform) with pluggable adapter architecture, supporting both webhook and polling connection modes in a unified framework. The message component system preserves semantic structure across platforms via an intermediate AST representation rather than string-based serialization.
vs alternatives: Handles more platforms natively (Discord, Telegram, QQ, web) than most open-source alternatives, with explicit support for both push (webhook) and pull (polling) connection patterns in a single codebase.
AstrBot implements a provider abstraction layer that unifies access to multiple LLM backends (OpenAI, Anthropic, Gemini, Ollama, local models) through a common interface. The system manages provider lifecycle (initialization, authentication, model selection), handles streaming responses with token-level granularity, implements context compression strategies to fit conversations within token limits, and provides automatic retry logic with exponential backoff. Provider configuration separates sources (API credentials) from instances (model + parameter combinations), enabling multi-model deployments and A/B testing without credential duplication.
Unique: Separates provider sources (credentials) from instances (model + parameters), enabling credential reuse across multiple model configurations. Implements context compression at the provider layer with pluggable strategies (summarization, sliding window, semantic deduplication) rather than forcing compression at the application level.
vs alternatives: Supports more LLM providers natively (OpenAI, Anthropic, Gemini, Ollama, local) than most frameworks, with explicit separation of credentials from model instances enabling multi-model deployments and cost optimization without code changes.
AstrBot implements a hierarchical configuration system that loads settings from YAML/JSON files, environment variables, and runtime API calls. The system supports configuration hot-reloading without application restart, environment variable interpolation (e.g., `${OPENAI_API_KEY}`), configuration validation against schemas, and configuration versioning. Configuration is organized into sections (platform settings, provider settings, feature flags, etc.), with defaults provided for all settings. The configuration API allows runtime updates to settings, which are persisted to disk and applied immediately.
Unique: Implements hierarchical configuration with hot-reloading support, enabling runtime updates without application restart. Environment variable interpolation and schema validation provide flexibility and safety for multi-environment deployments.
vs alternatives: Hot-reload capability eliminates the need for application restarts when updating configuration. Hierarchical configuration with environment variable interpolation simplifies multi-environment deployments compared to static configuration files.
AstrBot implements a media handling layer that normalizes file uploads and attachments across platforms, stores files in a configurable backend (local filesystem, S3, etc.), and transforms media for platform-specific requirements. The system handles file type validation, size limits, virus scanning (optional), and generates platform-specific attachment objects (Discord embeds, Telegram InputFile, etc.). The file service provides a unified API for uploading, downloading, and deleting files, with support for temporary files and automatic cleanup.
Unique: Implements platform-specific attachment transformation, converting normalized file objects into platform-native formats (Discord embeds, Telegram InputFile, etc.). Configurable storage backend enables deployment flexibility without code changes.
vs alternatives: Unified file service API abstracts platform-specific file handling, reducing boilerplate. Configurable storage backend supports local, S3, and cloud storage without code changes.
AstrBot implements an i18n system that supports multiple languages for UI, agent responses, and system messages. Language packs are loaded from JSON/YAML files, with support for pluralization, variable interpolation, and context-specific translations. The system detects user language from platform metadata (Discord locale, Telegram language_code) or explicit user preference, and applies translations at the UI and agent level. Theming system allows customization of dashboard appearance (colors, fonts, layout) via configuration files.
Unique: Implements i18n at both UI and agent levels, with automatic language detection from platform metadata. Theming system provides configuration-driven customization without requiring CSS knowledge.
vs alternatives: Automatic language detection from platform metadata eliminates explicit user language selection. Configuration-driven theming reduces boilerplate compared to manual CSS customization.
AstrBot implements a dual-mode tool execution system: native function tools defined via Python decorators or JSON schemas, and remote MCP (Model Context Protocol) servers for standardized tool discovery and execution. The system maintains a tool registry, validates tool call arguments against schemas, executes tools in an isolated sandbox context with restricted access to system resources, and handles tool results with error recovery. MCP integration enables tools to be defined in any language and discovered dynamically, while native tools provide low-latency execution for performance-critical operations.
Unique: Implements a hybrid tool system supporting both native Python functions (via decorators) and remote MCP servers, with unified schema validation and sandboxed execution. The MCP integration follows the Model Context Protocol standard, enabling interoperability with Claude and other MCP-compatible platforms.
vs alternatives: Combines low-latency native tool execution with MCP server flexibility, supporting tool definitions in any language. Explicit sandbox isolation and schema validation provide security guarantees that simpler function-calling implementations lack.
AstrBot implements a plugin architecture (called 'Stars') built on an event bus that decouples plugins from core systems. Plugins register event handlers and commands at startup, can be loaded/unloaded dynamically without restarting the application, and persist configuration in a plugin-specific storage layer. The system includes a plugin marketplace for discovery and installation, automatic dependency resolution, and a context API that provides plugins with access to agent state, configuration, and platform adapters. Hot reload enables rapid iteration during development by reloading plugin code without losing application state.
Unique: Uses an event bus abstraction to decouple plugins from core systems, enabling hot reload without application restart. Plugin marketplace integration with automatic discovery and installation provides a distribution mechanism similar to VS Code extensions or npm packages.
vs alternatives: Supports hot reload for rapid plugin development, with a marketplace for community distribution. Event-driven architecture decouples plugins from core logic, reducing coupling compared to hook-based systems.
AstrBot implements a multi-stage message processing pipeline that routes incoming messages through security/filtering stages (content moderation, rate limiting, permission checks), a main agent processing stage (LLM inference + tool execution), and result decoration stages (formatting, embedding generation, response assembly). Each stage is pluggable and can be extended or replaced. The pipeline uses an async/await pattern for non-blocking I/O and supports streaming responses where intermediate results are sent to the user before the full response is complete. Pipeline stages have access to a shared context object containing message metadata, agent state, and configuration.
Unique: Implements a pluggable multi-stage pipeline with explicit separation of concerns (security → processing → decoration), where each stage has access to a shared context object. Supports streaming responses at the pipeline level, enabling real-time token delivery to clients.
vs alternatives: Explicit pipeline stages with pluggable architecture provide more control than monolithic message handlers. Built-in streaming support enables real-time responses without requiring custom WebSocket implementations.

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.

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.
