Translates LLM decisions into browser actions by maintaining a bidirectional bridge between language model outputs and Chrome DevTools Protocol (CDP) commands. The Agent system executes a loop where it captures browser state (DOM, screenshots, page metadata), sends structured context to an LLM provider (OpenAI, Anthropic, Gemini, or local models), parses the LLM's action schema output, and executes actions like click, type, navigate, and extract through CDP. Includes built-in error recovery, loop detection, and behavioral nudges to prevent agent stalling.
Unique: Implements a closed-loop agent system with event-driven DOM processing (Watchdog pattern), structured output schema optimization per LLM provider, and message compaction to fit long tasks within token budgets. Unlike Playwright-only automation, browser-use couples LLM reasoning with real-time browser state feedback, enabling adaptive behavior. The DOM serialization pipeline uses visibility calculations and coordinate transformation to provide pixel-accurate click targets.
vs alternatives: Outperforms Selenium/Playwright scripts on novel tasks because the LLM adapts to UI changes without code rewrites; faster than cloud RPA platforms (UiPath, Automation Anywhere) for prototyping because it's open-source and runs locally with any LLM.
Converts raw HTML/CSS/JavaScript DOM trees into LLM-readable markdown and text formats by traversing the DOM, detecting interactive elements (buttons, inputs, links), calculating visibility based on CSS and viewport geometry, and assigning stable numeric indices. The DOM Processing Engine uses a Watchdog pattern to monitor DOM mutations, re-serialize only changed subtrees, and maintain coordinate mappings for accurate click targeting. Outputs include markdown extraction (headings, text content), HTML serialization with element indices, and a browser state summary with page title and URL.
Unique: Uses a Watchdog pattern with event-driven re-serialization instead of full-page re-parsing on every state change, reducing overhead. Implements visibility calculation via viewport intersection, CSS computed styles, and z-index stacking context analysis. Maintains a stable element index mapping across DOM mutations, enabling consistent LLM references even as the page updates.
vs alternatives: More efficient than Selenium's element finding because it pre-computes all interactive elements and their coordinates in a single pass; more accurate than regex-based HTML parsing because it uses actual CSS computed styles for visibility.
Extracts structured data from web pages by defining a schema (JSON Schema or Pydantic model) and using the agent to navigate to the relevant page, locate the data, and extract it in the specified format. The extraction action validates the extracted data against the schema and returns structured output (JSON, Python objects). Supports both single-page extraction (extract data from current page) and multi-page extraction (navigate through pages and aggregate results). Includes error handling for schema validation failures and retry logic for incomplete extractions.
Unique: Integrates schema-based validation into the extraction action, ensuring extracted data matches the expected format. Supports both single-page and multi-page extraction with aggregation. Uses the agent's reasoning to locate and extract data rather than brittle selectors.
vs alternatives: More flexible than regex-based scraping because it uses LLM reasoning to understand page structure; more robust than selector-based extraction because it adapts to layout changes.
Tracks agent execution metrics (actions taken, LLM calls, tokens used, time elapsed) and estimates costs based on LLM provider pricing. Collects telemetry data on agent performance, error rates, and task completion rates. Supports optional cloud sync to aggregate metrics across multiple agent runs and deployments. Provides detailed cost breakdowns per LLM provider and per task. Includes privacy controls to disable telemetry collection if needed.
Unique: Provides detailed cost estimation per LLM provider and per task, with support for cloud sync to aggregate metrics across multiple runs. Includes privacy controls to disable telemetry collection. Tracks both execution metrics and cost data.
vs alternatives: More comprehensive than basic logging because it includes cost estimation and performance metrics; more flexible than cloud-only solutions because it supports local telemetry collection with optional cloud sync.
Enables developers to define custom actions beyond the built-in set (click, type, navigate, extract) by registering custom tool classes that implement a standard interface. Custom tools are integrated into the action execution pipeline and exposed to the LLM as available actions. Supports tool-specific error handling, validation, and documentation. Tools are discovered at runtime and can be dynamically registered or unregistered. Includes examples and templates for common custom tools (screenshot, download, execute JavaScript).
Unique: Provides a standard tool interface for custom action registration with runtime discovery and dynamic registration/unregistration. Custom tools are automatically exposed to the LLM as available actions. Includes examples and templates for common custom tools.
vs alternatives: More extensible than fixed action sets because it supports custom tool registration; more flexible than plugin systems because tools are registered at runtime without requiring application restart.
Abstracts LLM provider differences (OpenAI, Anthropic Claude, Google Gemini, local Ollama) behind a unified interface that automatically optimizes action schemas per provider's capabilities. Handles provider-specific structured output formats (OpenAI's JSON mode, Anthropic's tool_use, Gemini's function calling), manages token counting and cost tracking, implements exponential backoff retry logic for rate limits and transient failures, and serializes agent state into provider-specific message formats. Supports both cloud-based and local LLM backends with fallback chains.
Unique: Implements provider-agnostic action schema that auto-adapts to each LLM's structured output capabilities (JSON mode, tool_use, function calling). Includes built-in token counting per provider with cost tracking, and fallback chains allowing seamless provider switching on failure. Message serialization uses provider-specific optimizations (e.g., Anthropic's vision_image format for screenshots).
vs alternatives: More flexible than LangChain's LLM abstraction because it optimizes schemas per provider rather than forcing a lowest-common-denominator format; cheaper than cloud-only solutions because it supports local LLMs with the same agent code.
Detects when an agent enters repetitive action cycles (e.g., clicking the same button repeatedly, typing the same text) by comparing recent action history and DOM snapshots. When a loop is detected, the system applies behavioral nudges: suggesting alternative actions, modifying the system prompt to encourage exploration, or triggering a 'judge' evaluation to assess task progress. Uses heuristics like action frequency analysis, DOM change detection, and coordinate repetition to identify stalls. Includes configurable thresholds and nudge strategies.
Unique: Combines action frequency analysis, DOM change detection, and coordinate repetition heuristics to identify loops without requiring explicit task state. Applies graduated nudges (prompt modification, alternative suggestions, judge evaluation) rather than hard stops, allowing the agent to recover gracefully. Integrates with the Judge system for progress assessment.
vs alternatives: More sophisticated than simple action count limits because it analyzes DOM changes and action semantics; more flexible than hard timeouts because it adapts nudges based on loop type.
Automatically compresses agent conversation history to fit within LLM context windows by summarizing old messages, removing redundant state information, and prioritizing recent actions. Uses a compaction strategy that identifies the most important historical context (e.g., task definition, key decisions) while discarding verbose intermediate steps. Tracks token usage across the conversation and triggers compaction when approaching the LLM's max_tokens limit. Maintains a compact representation of agent state (current page, recent actions, key findings) to preserve context fidelity.
Unique: Implements adaptive compaction that triggers based on token budget utilization rather than fixed message counts, preserving recent context while summarizing older messages. Maintains a compact state representation (current page, recent actions, key findings) separate from full message history, allowing recovery of context after compaction.
vs alternatives: More efficient than naive message truncation because it preserves semantic context through summarization; more flexible than fixed context windows because it adapts compaction strategy based on task progress.

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 browser-use at 47/100. browser-use leads on adoption, while TrendRadar is stronger on quality and ecosystem.

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.
