Receives distributed traces via gRPC server listening on port 4317 using the OpenTelemetry Line Protocol (OTLP). Spans are parsed from protobuf messages, validated, and persisted to PostgreSQL or SQLite with full trace context preservation including parent-child relationships, attributes, and timing metadata. Supports auto-instrumentation from Python and TypeScript SDKs without code modification.
Unique: Native gRPC OTLP server implementation (not HTTP-based) with direct protobuf deserialization, enabling low-latency trace ingestion without JSON serialization overhead. Monorepo structure includes language-specific auto-instrumentation SDKs (Python/TypeScript) that register with the server automatically.
vs alternatives: Faster ingestion than HTTP-based OTLP collectors (e.g., OpenTelemetry Collector) because it eliminates JSON serialization and uses gRPC's binary protocol directly; open-source alternative to proprietary APM vendors like Datadog or New Relic.
Exposes traces via Strawberry GraphQL API (src/phoenix/server/api/schema.py) enabling complex queries on span hierarchies, attributes, and relationships. Supports filtering by span kind, status, duration, and custom attributes. Frontend (React/TypeScript in app/) renders interactive trace waterfall diagrams with collapsible span trees, latency heatmaps, and error highlighting. Queries execute against PostgreSQL/SQLite with indexed lookups on trace_id and span_id.
Unique: Strawberry GraphQL implementation with typed schema generation from Python dataclasses, enabling schema-first API design. Frontend uses React hooks for real-time span tree rendering with collapsible hierarchies and latency waterfall visualization — not just raw JSON dumps.
vs alternatives: More flexible querying than Jaeger's UI-only trace search because GraphQL enables programmatic access; better visualization than raw Elasticsearch queries because frontend renders interactive waterfall diagrams with span relationships.
CLI tool (src/phoenix/cli/) provides commands for starting the Phoenix server, exporting traces/datasets to CSV/JSON, and managing database migrations. Supports configuration via environment variables or CLI flags. Enables headless operation for CI/CD pipelines and batch data processing. Export functionality supports filtering by trace ID, span name, or time range.
Unique: CLI tool integrated with Phoenix server enabling headless operation and data export. Supports configuration via environment variables or flags. Export functionality includes filtering by trace ID, span name, or time range.
vs alternatives: More flexible than web UI for automation because it supports scripting and CI/CD integration; more accessible than programmatic API for simple operations like server startup and data export.
React/TypeScript frontend (app/) renders traces, datasets, and experiments with interactive UI. Trace viewer displays span waterfall diagrams with collapsible hierarchies, latency heatmaps, and error highlighting. Real-time updates via WebSocket or polling. State management via React hooks and context. Supports dark/light theming. Responsive design for desktop and tablet. Integrates with GraphQL API for data fetching.
Unique: React frontend with interactive trace waterfall visualization including collapsible span hierarchies and latency heatmaps. Real-time updates via WebSocket or polling. State management via React hooks and context. Responsive design for desktop and tablet.
vs alternatives: More interactive than static dashboards (Grafana) because it enables drill-down into individual traces; more user-friendly than CLI-only tools because it provides visual trace exploration without command-line knowledge.
Provides Kubernetes deployment manifests (kustomize/) and Helm charts for deploying Phoenix in production. Includes ConfigMaps for configuration, Secrets for API keys, StatefulSets for database, and Deployments for application server. Supports horizontal scaling of the application layer. Health checks and resource limits configured. Documentation for common deployment patterns (single-node, multi-replica, with external PostgreSQL).
Unique: Kubernetes-native deployment with both Helm charts and Kustomize support. Includes ConfigMaps for configuration, Secrets for API keys, and StatefulSets for database. Supports horizontal scaling of application layer with shared database backend.
vs alternatives: More flexible than Docker Compose because it supports production-grade features (health checks, resource limits, scaling); more standardized than custom deployment scripts because it uses Kubernetes native mechanisms.
Implements authentication via API keys (long-lived tokens for programmatic access) and session tokens (short-lived tokens for web UI). Authorization is role-based (admin, user, viewer) with fine-grained permissions on datasets and experiments. API keys are stored hashed in database. Session tokens are JWT-based with configurable expiration. Supports optional OIDC integration for enterprise SSO.
Unique: Dual authentication mechanism: API keys for programmatic access and session tokens (JWT) for web UI. Role-based authorization with fine-grained permissions on datasets and experiments. Optional OIDC integration for enterprise SSO.
vs alternatives: More flexible than single-token systems because it supports both long-lived API keys and short-lived session tokens; more enterprise-friendly than no authentication because it includes OIDC support for SSO.
Python evaluation framework (packages/phoenix-evals/) provides pre-built evaluators for LLM applications: retrieval quality (NDCG, precision@k), hallucination detection, toxicity scoring, and custom LLM-as-judge evaluations. Evaluators are composable functions that accept span data or datasets and return structured scores. Supports both sync and async execution with batching. Integrates with experiment tracking to compare evaluator results across prompt/model variants.
Unique: Pluggable evaluator architecture where evaluators are Python callables with standardized input/output contracts, enabling composition and reuse. Includes pre-built evaluators for RAG (NDCG, precision@k) and LLM safety (toxicity, hallucination) without requiring external libraries. Async-first design with batching support for efficient evaluation of large datasets.
vs alternatives: More specialized for LLM evaluation than generic ML metrics libraries (scikit-learn) because it includes LLM-specific evaluators (hallucination, toxicity) and integrates with trace data; more flexible than closed-source evaluation platforms (e.g., Weights & Biases) because evaluators are open-source Python code.
Manages datasets and experiments as first-class objects in Phoenix. Datasets are versioned collections of examples (query, response, reference) stored in the database. Experiments link datasets to prompt/model configurations and store evaluation results. Supports creating datasets from traces, uploading CSV/JSON, and comparing experiment results side-by-side. Experiment tracking stores metadata (model, prompt version, hyperparameters) alongside evaluation scores for reproducibility.
Unique: Integrated dataset and experiment management within the observability platform (not a separate tool). Datasets are versioned and queryable; experiments link datasets to configurations and store evaluation results in a structured schema. Supports creating datasets from production traces, enabling closed-loop evaluation workflows.
vs alternatives: More integrated than external experiment tracking tools (Weights & Biases, MLflow) because datasets and experiments live in the same database as traces; more specialized for LLM evaluation than generic ML experiment platforms because it includes LLM-specific metadata (prompt version, model name).

Executes parallel web scraping tasks against Xianyu marketplace using Playwright browser automation (spider_v2.py), with concurrent task execution managed through Python asyncio. Each task maintains independent browser sessions, cookie/session state, and can be scheduled via cron expressions or triggered in real-time. The system handles login automation, dynamic content loading, and anti-bot detection through configurable delays and user-agent rotation.
Unique: Uses Playwright's native async/await patterns with independent browser contexts per task (spider_v2.py), enabling true concurrent scraping without thread management overhead. Integrates task-level cron scheduling directly into the monitoring loop rather than relying on external schedulers, reducing deployment complexity.
vs alternatives: Faster concurrent execution than Selenium-based scrapers due to Playwright's native async architecture; simpler than Scrapy for stateful browser automation tasks requiring login and session persistence.
Analyzes scraped product listings using multimodal LLMs (OpenAI GPT-4V or Google Gemini) through src/ai_handler.py. Encodes product images to base64, combines them with text descriptions and task-specific prompts, and sends to AI APIs for intelligent filtering. The system manages prompt templates (base_prompt.txt + task-specific criteria files), handles API response parsing, and extracts structured recommendations (match score, reasoning, action flags).
Unique: Implements task-specific prompt injection through separate criteria files (prompts/*.txt) combined with base prompts, enabling non-technical users to customize AI behavior without code changes. Uses AsyncOpenAI for concurrent product analysis, processing multiple products in parallel while respecting API rate limits through configurable batch sizes.
vs alternatives: More flexible than keyword-based filtering (handles subjective criteria like 'good condition'); cheaper than human review workflows; faster than sequential API calls due to async batching.

Provides Docker configuration (Dockerfile, docker-compose.yml) for containerized deployment with isolated environment, dependency management, and reproducible builds. The system uses multi-stage builds to minimize image size, includes Playwright browser installation, and supports environment variable injection via .env file. Docker Compose orchestrates the service with volume mounts for config persistence and port mapping for web UI access.
Unique: Uses multi-stage Docker builds to separate build dependencies from runtime dependencies, reducing final image size. Includes Playwright browser installation in Docker, eliminating the need for separate browser setup steps and ensuring consistent browser versions across deployments.
vs alternatives: Simpler than Kubernetes-native deployments (single docker-compose.yml); reproducible across environments vs local Python setup; faster than VM-based deployments due to container overhead.
Implements resilient error handling throughout the system with exponential backoff retry logic for transient failures (network timeouts, API rate limits, temporary service unavailability). Playwright scraping includes retry logic for page load failures and element not found errors. AI API calls include retry logic for rate limit (429) and server error (5xx) responses. Failed tasks log detailed error traces for debugging and continue processing remaining tasks.
Unique: Implements exponential backoff retry logic at multiple levels (Playwright page loads, AI API calls, notification deliveries) with consistent error handling patterns across the codebase. Distinguishes between transient errors (retryable) and permanent errors (fail-fast), reducing unnecessary retries for unrecoverable failures.
vs alternatives: More resilient than no retry logic (handles transient failures); simpler than circuit breaker pattern (suitable for single-instance deployments); exponential backoff prevents thundering herd vs fixed-interval retries.
Provides health check endpoints (/api/health, /api/status/*) that report system status including API connectivity, configuration validity, last task execution time, and service uptime. The system monitors critical dependencies (OpenAI/Gemini API, Xianyu marketplace, notification services) and reports their availability. Status endpoint includes configuration summary, active task count, and system resource usage (memory, CPU).
Unique: Implements comprehensive health checks for all critical dependencies (AI APIs, Xianyu marketplace, notification services) in a single endpoint, providing a unified view of system health. Includes configuration validation checks that verify API keys are present and task definitions are valid.
vs alternatives: More comprehensive than simple liveness probes (checks dependencies, not just process); simpler than full observability stacks (Prometheus, Grafana); built-in vs external monitoring tools.
Routes AI-generated product recommendations to users through multiple notification channels (ntfy.sh, WeChat, Bark, Telegram, custom webhooks) configured in src/config.py. Each notification includes product details, AI reasoning, and action links. The system supports channel-specific formatting, retry logic for failed deliveries, and notification deduplication to avoid spamming users with duplicate matches.
Unique: Implements channel-agnostic notification abstraction with pluggable handlers for each platform, allowing new channels to be added without modifying core logic. Supports task-level notification routing (different tasks can use different channels) and deduplication based on product ID + task combination.
vs alternatives: More flexible than single-channel solutions (e.g., email-only); supports Chinese platforms (WeChat, Bark) natively; simpler than building separate integrations for each notification service.
Provides FastAPI-based REST endpoints (/api/tasks/*) for creating, reading, updating, and deleting monitoring tasks. Each task is persisted to config.json with metadata (keywords, price filters, cron schedule, prompt reference, notification channels). The system streams real-time execution logs via Server-Sent Events (SSE) at /api/logs/stream, allowing web UI to display live task progress. Task state includes execution history, last run timestamp, and error tracking.
Unique: Combines task CRUD operations with real-time SSE logging in a single FastAPI application, eliminating the need for separate logging infrastructure. Task configuration is stored in version-controlled JSON (config.json), allowing tasks to be tracked in Git while remaining dynamically updatable via API.
vs alternatives: Simpler than Celery/RQ for task management (no separate broker/worker); real-time logging via SSE is more efficient than polling; JSON persistence is more portable than database-dependent solutions.
Executes monitoring tasks on two schedules: (1) cron-based recurring execution (e.g., '0 9 * * *' for daily 9 AM checks) parsed and managed in spider_v2.py, and (2) real-time on-demand execution triggered via API or manual intervention. The system maintains a task queue, respects concurrent execution limits, and logs execution timestamps. Cron scheduling is implemented using APScheduler or similar, with task state persisted across restarts.
Unique: Integrates cron scheduling directly into the monitoring loop (spider_v2.py) rather than using external schedulers like cron or systemd timers, enabling dynamic task management via API without restarting the service. Supports both recurring (cron) and on-demand execution from the same task definition.
vs alternatives: More flexible than system cron (tasks can be updated via API); simpler than distributed schedulers like Celery Beat (no separate broker); supports both scheduled and on-demand execution in one system.
