MetaGPT assigns distinct LLM-powered roles (Product Manager, Architect, Engineer, QA) to collaborate as a simulated software company. Each role executes domain-specific actions sequentially, with message passing between roles enabling task decomposition and workflow coordination. The framework uses a Role base class with action queues and memory systems to maintain role-specific context across multi-turn interactions, simulating realistic software development workflows where roles depend on outputs from upstream roles.
Unique: Uses a Role-Action-Message architecture where roles are stateful agents with persistent memory, action queues, and message-based communication. Unlike simple function-calling agents, each role maintains its own context and can iterate on tasks. The framework includes pre-built roles (Engineer, ProductManager, Architect, QA) with domain-specific prompts and ActionNode definitions that structure outputs for downstream consumption.
vs alternatives: Differs from AutoGPT/BabyAGI by providing explicit role specialization and structured workflows rather than generic task decomposition, enabling more predictable multi-agent collaboration patterns similar to real software teams.
ActionNode is a declarative system for defining LLM output schemas with automatic prompt generation, parsing, and validation. Each ActionNode specifies expected output fields with types, descriptions, and validation rules. MetaGPT generates prompts that guide the LLM to produce structured outputs (JSON, code, markdown), then parses and validates responses against the schema. If validation fails, the system can trigger automatic revision loops where the LLM corrects its output based on validation errors.
Unique: Implements a declarative schema system where output structure is defined once and reused for prompt generation, parsing, and validation. Uses Pydantic models to define schemas, automatically generates prompts that teach the LLM the expected format, and includes a revision system that feeds validation errors back to the LLM for self-correction. This is more sophisticated than simple regex parsing or JSON extraction.
vs alternatives: More robust than manual prompt engineering + regex parsing because it couples schema definition with validation and automatic retry logic, reducing the need for brittle post-processing code.
MetaGPT includes a MockLLM class that simulates LLM responses for testing without making actual API calls. The system also implements response caching where real LLM responses are cached and replayed in subsequent runs. This enables fast iteration during development and reproducible testing. Cache is stored in JSON files and can be versioned with git.
Unique: Provides both MockLLM for simulated responses and response caching for real LLM calls. Caches are stored in JSON files that can be version-controlled, enabling reproducible tests. The system can switch between mock and real LLMs without code changes.
vs alternatives: More comprehensive than simple mocking because it combines mock responses with real response caching, enabling both fast development and reproducible testing.
MetaGPT supports serializing the entire execution context (roles, messages, artifacts, configuration) to enable workflow resumption from checkpoints. The Context class manages runtime state and can be serialized to JSON or other formats. This enables long-running workflows to be paused and resumed, or migrated across systems. Context recovery reconstructs the full agent state including memory and message history.
Unique: Serializes the entire execution context including roles, messages, artifacts, and configuration, enabling complete workflow recovery. Context snapshots can be stored and recovered, supporting both pause-resume and cross-system migration.
vs alternatives: More comprehensive than simple state saving because it captures the full execution context including message history and agent memory, not just final outputs.
MetaGPT implements a schema-based function calling system where tools are defined with Pydantic models or JSON schemas, and the framework translates these to provider-specific function calling formats (OpenAI, Anthropic, etc.). The system handles function call parsing, validation, and execution. Tools can be registered globally or per-role, and the framework manages the function calling loop (LLM calls function → execute → return result → LLM continues).
Unique: Implements a provider-agnostic function calling system where tools are defined once using Pydantic schemas and automatically translated to each provider's format. The framework handles the function calling loop and manages provider-specific quirks (e.g., OpenAI's tool_choice parameter, Anthropic's tool_use blocks).
vs alternatives: More robust than manual function calling because it abstracts provider differences and includes automatic validation and error handling, reducing the need for provider-specific code.
MetaGPT supports multi-modal inputs including images and vision models. Agents can process images, extract information, and generate descriptions or code based on visual content. The framework integrates vision capabilities with the standard LLM provider system, enabling agents to analyze screenshots, diagrams, or other visual artifacts. Vision model responses are integrated into the message stream and can be used by downstream agents.
Unique: Integrates vision model support into the standard LLM provider system, enabling agents to process images alongside text. Vision responses are treated as regular messages and can be consumed by downstream agents, enabling workflows that combine visual and textual reasoning.
vs alternatives: More integrated than separate vision APIs because vision capabilities are built into the agent framework, enabling seamless multi-modal workflows without additional orchestration.
ProjectRepo is a file system abstraction that manages code artifacts, design documents, and project metadata with automatic git integration. It provides methods to write files, commit changes, and maintain project structure. The system tracks file modifications, enables incremental development by reading previous outputs, and integrates with git for version control. Artifacts are organized by type (code, docs, tests) and can be retrieved for downstream processing or review.
Unique: Provides a high-level abstraction over git operations (write, commit, read) that agents can use without directly invoking git commands. Maintains a mapping of file types to directories and enables agents to query the project structure. Includes methods for reading previous artifacts to support incremental development where agents build on prior outputs.
vs alternatives: Simpler than agents directly calling git CLI because it abstracts away git complexity and provides semantic methods (write_code, write_doc) that are easier for LLMs to use correctly.
MetaGPT implements a BaseLLM abstract class with concrete implementations for OpenAI, Anthropic, Azure, AWS Bedrock, and OpenAI-compatible providers (Ollama, vLLM). The system includes a provider registry that routes requests to the appropriate LLM backend based on configuration. Token counting and cost tracking are built-in, with support for streaming responses and function calling across different provider APIs. Configuration is centralized and can be overridden per-request.
Unique: Implements a provider registry pattern where each LLM provider (OpenAI, Anthropic, Bedrock, etc.) is a concrete implementation of BaseLLM. The framework handles provider-specific API differences transparently, including function calling schema translation and streaming response handling. Token counting is integrated per-provider with cost calculation.
vs alternatives: More comprehensive than LiteLLM because it includes token counting, cost tracking, and streaming support natively, plus tight integration with the multi-agent framework for role-specific provider selection.

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 MetaGPT 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.
