Monitor WordPress Performance with WPStack TOP Load Monitor

WPStack TOP Load Monitor is a free WordPress plugin designed to provide developers and site administrators with deep insights into their website's performance. It offers real-time monitoring of requests, slow queries, memory usage, PHP errors, and plugin performance through live dashboards and smart insights.

• Core Monitoring: Captures request load, memory delta, query count, slow queries, duplicate queries, request context, and PHP errors.
• Live Visibility: Features a live admin-bar indicator for load time, query count, and memory, along with a real-time dashboard displaying metric cards, performance charts, recent requests, alerts, slow queries, errors, process breakdowns, and smart insights.
• Native Smart Insights: Builds a rolling baseline from recent snapshots to flag statistically unusual performance, detects N+1 query patterns, and generates focused recommendations for common WordPress data structures.
• Plugin Performance Attribution: Ranks plugins by their performance cost based on hook time, slow-query time, and duplicate-query signals.
• Optional AI Assistance: Integrates with NVIDIA or OpenRouter (via OpenAI-compatible API) for enhanced root-cause summaries, actionable optimization suggestions, and a contextual AI chat assistant. Data is only sent externally if an administrator explicitly configures a provider.
• Alerting and Developer Tooling: Provides configurable thresholds for various performance metrics, deduplicates alerts, and includes a REST API for accessing dashboard data, snapshots, and settings.

The plugin works entirely within WordPress without requiring Composer or external monitoring services. It is easy to install and activate, offering a clear, practical view of what impacts your WordPress site's performance.
